Significant technological developments, particularly in cyber warfare, electromagnetic spectrum operations (EMSO), and precision fires, are fast becoming more accessible to opponents, thereby threatening to change the delicate landscape of global security and power dynamics.

According to Comtech’s Chief Strategy Officer and President of the Company’s Satellite Network Technologies business, Daniel Gizinski, today’s threat landscape looks wildly different from five to 10 years ago.

“There’s been a dramatic adjustment, both in terms of the capabilities and how and where they’re being deployed,” he explained.

“We’ve seen some pretty significant developments as a result of innovations and change, and over the last several years, we’ve had the opportunity to look at very different levels of what’s possible and what can be done. And from a product development and program fielding perspective, this change has put a lot of emphasis on how we design and develop products that can last over a long-term period in the field,” he continued to describe.

According to Daniel, the pivot towards strategic competition presents an “enormous challenge” to the US Department of Defense (DoD) and its international partners as they look to build and design products capable of being fielded for the next 10 to 25 years.

To support the warfighter both today and in the future, Comtech continues to focus on upgrading legacy systems as well as the development of emerging, next-generation technologies.

“The net result of this change has been a shift away from the development of bigger, more expensive, more hardened systems including advanced wideband waveforms and satellites capable of tolerating levels of spectral interference towards enormous investment in building out resilience in connectivity,” Daniel explained.

“Resilience on the battlefield lies in the diversity of multiple networks capable of providing the necessary levels of connectivity to route traffic via the best available network. Ultimately, the goal isn’t necessarily to keep a network running at all costs—it’s to keep data getting to the right place at all costs. And there are sometimes more efficient ways to do that, and you must bake in that headroom and that ability to adapt via software updates to maintain pace with a rapidly changing threat,” he added.

Uniquely Positioned

Consequently, Comtech continues to focus efforts on a series of technology areas of interest to support DoD and international partners.

Focus areas include Assured Communications and EMSO, with Daniel explaining how the company remains “hyper-focused” on the transition away from heavily stove-piped satellite systems towards digital satellite ground infrastructure and other capabilities that allow the warfighter to rapidly reconstruct networks based on the requirements of any given day.

Similar sentiments were shared by Comtech’s Executive Vice President of Business Development and Sales, Roly Rigual, who explained how Assured Communications can support operations against near-peer adversaries today and in the future.

“It’s been a long time since the major powers have had to ‘fight to get to the fight’ so assured and protected communications are more important today than ever,” Roly explained, highlighting the proliferation of multi-orbit (LEO, MEO, and GEO) constellations.

“It’s just starting, but there’s a lot of technology that still needs to be developed and deployed alongside the relevant standards supported by the ground infrastructure. I believe Comtech is in a very good position to help the customer solve these challenges,” he said.

In terms of EMSO, Comtech has focused on developing new understandings and techniques over the past decade, particularly relating to improved coordination of electronic attacks and electronic support through communications.

Dual Use Expertise

As it continues to support DoD and international partners, Comtech benefits from expertise in both commercial and defense markets.

“As a company that’s got its roots in dual-use technology development, we design a lot of cutting-edge commercial technologies with a unique set of abilities and capabilities to develop defense articles,” Daniel explained.

“I wouldn’t necessarily say one is universally ahead of the other, but having a foot in both camps allows us to take clever commercial innovations and bring them to the defense market and vice versa.”

Daniel highlighted satellite and troposcatter communication solutions as two of the most relevant dual-use capabilities that, when stitched together, can offer DoD and international partners significant value across a battlespace.

Specific Comtech successes include the US Army’s Enterprise Digital Intermediate Frequency Modem (EDIM) program, which has its roots in commercially developed technology. Awarded a contract in October 2023, Comtech is on track to deliver an initial tranche of systems to the army in the coming months.

Elsewhere, Comtech continues to support a resurgence in Troposcatter technologies across the US Army, Marine Corps, and international partners.

“Troposcatter was viewed as legacy technology-heavy, expensive, and hard to deploy. But it’s been fun to see the look of realization and appreciation that sets in with certain customers when they realize the art of the possible with modern solutions,” Daniel said.

Furthermore, Comtech is in the process of rolling out a next-generation of satellite modems capable of supporting exquisite platforms such as combat air aircraft.

“We recently received an award to bring some of the most advanced military jets into the overall network, so this is a pretty exciting growth opportunity and part of a new modem family we’re in the process of releasing over the next six or so months,” Daniel said.

Finally, Comtech remains dedicated to ensuring customers benefit from ‘Zero Trust Architecture’ as they move away from traditional network-centric infrastructures towards more data-centric models.

“One of the biggest challenges we see is bridging legacy and new networks together. I think everyone likes to imagine that we will flip a light switch and have zero trust architecture rolled out next year, but it’s going to be a 10-plus year roll-out process,” he concluded.

As the contemporary operating environment continues to change, so too must connectivity products and solutions over the long term to ensure the warfighter benefits from truly resilient communications.

Only increasing levels of investment and diverse inventories of products and concepts of operation will support those who need it most as they continue to observe uplifts in asymmetric warfare around the world.

When James Thomas was named Comtech’s Vice President of Government Affairs earlier this month, it marked “an exciting opportunity to help Comtech shape important policies that positively impact our customers and the world,” James explained.

Hiring James Thomas represents an important milestone for Comtech in the company’s growth trajectory. With Thomas now onboard, Comtech adds an experienced “voice in the room” at an important time, as the company’s breakthrough technologies are playing an increasingly pivotal role in connectivity solutions that are changing, saving, and improving lives across the globe.

“Navigating today’s political and policy environment is both challenging and fulfilling,” said James, who has worked most of his nearly 20-year career educating lawmakers and advocating for a wide range of policies in Washington, DC ranging from international trade issues to space and emerging satellite communications and sensor technologies that will be of particular benefit to Comtech as the company presses forward with core campaigns to transform technology, national security, and connectivity landscapes across the globe.

His vast expertise has been honed by a mix of experience in Congress, the Executive Branch during two Presidential administrations, the Department of Defense, and most recently in the private sector. Prior to joining Comtech, Thomas was the director of government affairs for national security programs at Leidos, fulfilling what he calls his trifecta of expertise in two branches of government and the corporate world.

“I’ve gained invaluable experience in the legislative and executive branches of government, as well as the private sector. I’m privileged to be in this role at Comtech, to be able to share with key decision makers in Washington the incredible breakthroughs and innovative work being done by our team,” James noted. “Technology trajectories today are creating an increasingly complex environment that call for equally sophisticated terrestrial and satellite-based solutions to make life safer for our communities, our warfighters, and the world.”

“With nearly two decades navigating the political and policy intricacies of Washington, James brings a vast array of experience to the Comtech team,” said John Ratigan, Interim CEO of Comtech. “We’re excited to welcome this Marine Corps veteran to share Comtech’s vision and secured communications capabilities with policymakers and government customers.”

Always Been About Service and Giving Back

James went to the University of Dayton in 2000 with the goal of becoming an attorney. His life’s gameplan changed in an instant on September 11, 2001, his sophomore year in college.

“I had an immediate calling to serve, so I put school on hold and joined the Marine Corps Reserves,” James recalls. “I was called up in 2003 and deployed to Iraq. When I returned to finish up my courses, it was a big election year, and a professor helped line me up with an internship with the Presidential campaign in Ohio, a major battleground state at the time.”

It was a taste of things to come suddenly put on hold, as Thomas was deployed to Iraq again in 2005. Shortly after his return home, James got a call from the White House with an offer for a job as a junior staffer. “It was an amazing experience,” James said. “But it wasn’t long before I joined the Commerce Department and started learning about the political process and understanding the impact legislators and committees have on the economy, business, and trade agreements. I was fascinated by it.”

In 2009, James joined the team supporting Congressman Duncan Hunter, a freshman legislator at the time and a fellow Marine and Iraq War veteran. Six years later, he jumped into the private sector with the National Defense Industrial Association, a trade group that counts Comtech as a member, where he was the chief representative before members of Congress and staff on policy matters impacting the defense industry.

His next stop was the Pentagon, where he served in several positions in the Department of Defense, most notably as a Senior Advisor to the Secretary and Undersecretary of the Air Force, and later as the Deputy Assistant Secretary of Defense for Senate Affairs. In this capacity, James was a senior advisor to the Secretary of Defense and Deputy Secretary of Defense, responsible for advocating the Department’s policies, strategies, and annual budget to the United States Congress as well as managing the Senate confirmation process for senior Department leadership positions to include the Secretary and Deputy Secretary of Defense.

James has countless career highlights but includes his work to help get the Senate onboard to pass legislation that would ultimately create the Space Force among his top accomplishments. “That was such a unique experience, having a small part in the creation of a military service branch. And now the Space Force is a beneficiary of our comprehensive satellite ground station technologies.”

Hitting the Ground Running

Fresh off a four-year stint with Leidos, where he managed government affairs through a company reorganization and leadership change, James is already hard at work in the nation’s capital generating awareness around Comtech’s accomplishments and future roadmaps.

“Over the next 90 days, the focus will be on thoroughly understanding the core competencies and capabilities of the company and deploying best practices for re-invigorating a Comtech political action committee (PAC) and government affairs function,” James outlined. “We will ensure that the key lawmakers know the capabilities that Comtech brings to important commercial and government markets – from bridging the digital divide to empowering emergency services and warfighters with unprecedented connectivity.”

James points to Comtech’s groundbreaking connectivity solutions and technologies as one of several key factors in his decision to join the company. “For me, it’s always been about service and giving back, and I’m looking forward thinking out of the box with the Comtech team and solving the problems and challenges out there – for communities and our armed forces.”

He sees it as an obligation to ensure there’s adequate funding to enable warfighters to do their job effectively and as safely as possible. “The battlefield is constantly adapting and changing, and Comtech is consistently demonstrating the ability to provide new innovations that deliver an edge to U.S. and allied forces,” James explained. “A top priority will be showcasing our success stories and evolving requirements with legislators and policymakers who are considering bills and appropriations at a time when there’s a lot of pressure on the defense budget.”

James Thomas lives in Northern Virginia, a short drive from the Washington, DC corridor that has had such an impact on his life and career. “Washington has afforded me some incredible opportunities, and I’m looking forward to my best one yet at Comtech. I’ll be gleaning important insights from teams across Comtech and representing our people and breakthroughs on the Hill, where ultimately the rubber meets the road when it comes to gaining visibility and funding for our customers, partners, and game-changing solutions.”

Operations in Contested/Congested Satellite Environments

Intro

In our increasingly interconnected world, satellite communications have become a cornerstone of modern communication networks, enabling global connectivity for everything from connecting rural communities to navigation and surveillance. However, according to US Space Command (August 31, 2023), as the demand for satellite bandwidth grows and more actors enter the space arena, the once-uncongested satellite environment is becoming increasingly contested. The contention poses significant challenges to traditional satellite communications systems, leading to exploration of alternative solutions. One such solution that has gained renewed attention is tropospheric scatter, or Troposcatter, communications.

Contested Satellite Environment

Satellite communication has long been favored for its ability to provide wide coverage and high bandwidth connectivity across vast distances. This advantage, however, according to the European Space Agency (April 21, 2022), has led to an overcrowded space environment. A similar finding by the Union of Concerned Scientists (January 1, 2023), indicates that governments, militaries,  and corporations,  are launching more satellites into orbit, resulting in increased competition for radio frequency (RF) spectrum and potential interference issues. Moreover, the emergence of anti-satellite technologies and rapid evolution of satellite-targeted cyber threats have raised concerns about the reliability and security of traditional satellite communications systems.

Understanding Troposcatter Communication

Troposcatter communications is a technology that leverages the scattering of radio waves in the Earth’s troposphere – the lower portion of the atmosphere – to establish communications links over distances  beyond the radio horizon or beyond line of site (BLOS). Today, modern Troposcatter technologies send signals towards the troposphere, where they interact with atmospheric particles and scatter in various directions. A receiver located within the scatter region can pick up the signal enabling robust, resilient, and secure communications between the transmitter and receiver.

Advantages in Contested Environments

 Comtech’s next generation Troposcatter Family of Systems offer several advantages in contested satellite environments:

1. Resistance to Jamming: Unlike traditional satellite signals that can be vulnerable to jamming or interference, Troposcatter signals are more resistant due to their reliance on atmospheric scattering. Attempts to jam a Troposcatter link would require jamming a significant portion of the Earth’s atmosphere, making such efforts impractical.
2. Reduced Susceptibility to Cyberattacks: Troposcatter connections provide a smaller attack surface than broad area satellite beams, increasing the difficulty, cost, and complexity of launching a successful cyberattack. This inherent security advantage makes Troposcatter an attractive option for transmitting sensitive information.
3. Distributed Architecture: Troposcatter technologies are designed with distributed architecture, enabling multiple relay stations to create a network that can adapt to changing conditions. This flexibility is particularly valuable in contested environments where fixed satellite infrastructure might be compromised.
4. Lower Latency: Modern Troposcatter systems offer lower latency compared to satellite communications, as the signal does not have to travel all the way to space and back. This can be crucial for real-time applications like video conferencing or remote-control critical systems.
5. Spectrum Efficiency: As spectrum becomes a limited resource in contested environments, Troposcatter can make more efficient use of available frequency bands, potentially mitigating spectrum congestion.

According to the National Defense Science and Technology Strategy (May 9, 2023), the DoD is focused on the optimization of the joint mission; creating and fielding capabilities at speed and scale; and ensuring the foundations for research and development.

As a trusted partner of the DoD, Comtech is evolving its strategic roadmap as the company looks to lead the way in providing smart networks, future communications, and new insights for the DoD. With a rich heritage in building exquisite and advanced hardware, Comtech is now focused on providing the DoD and coalition partners with added value through integrating software and solutions to exploit emerging capabilities.

According to Comtech’s Chief Strategy Officer, Daniel Gizinski, the company’s history in design and manufacturing provides the necessary building blocks required to offer the DoD turnkey solutions and services.

Comtech is also witnessing an evolution in its relationship with the DoD, which is pivoting away from a focus on product procurement to becoming an early adopter of technology through an increased focus on collaboration with strategic partners across the private sector.

“We see a lot more emphasis on Research Development Testing and Evaluation (RDT&E) associated with new capabilities, which is enormous. And especially within the US DoD, a huge focus on procuring services, rather than developing capabilities,” said Daniel. “I think that was always a struggle for the DoD in years past where there would be a great commercial offering available, but they focused instead on inventing a similar capability via a program of record.”

“We’ve seen a lot of flexibility in their ability to go out and discuss with industry, establish partners and then secure capability by employing consumption-based, ‘as-a-service’ business models. That’s driven a much closer set of relationships as our customers can be more open about what their needs are and more attuned to some of the advancements that we’re seeing in the commercial world,” Daniel said while highlighting dual-use technologies.

Converging technology

With over 50 years of proven technology leadership across cellular, terrestrial, and space-based technologies, Comtech is uniquely positioned to support the strategic all-domain command and control needs of the US DoD, Daniel believes.

“Ultimately, a majority of our future roadmap for Comtech’s defense solutions is directly in line with some of the core initiatives that are laid out under Combined Joint All Domain Command and Control (CJADC2) umbrella, so it’s helpful to have a broad array of expertise in wireless, terrestrial and satellite communications,” said Daniel.

Daniel went on to discuss a key challenge for the implementation of CJADC2—communications systems that were not designed to be interoperable. As Daniel shares, hundreds of different stovepipe systems that were never designed to interoperate with each other is a hurdle, but as he believes, integrating upgrades to existing systems and applying commercial best practices can address this challenge.

“It’s a hard problem but it’s one that has been solved particularly well in the private sector already,” said Daniel. “Comtech is able to bring a lot of the focus and lessons learned from its experience in commercial integration to support CJADC2 initiatives.”.

One capability in Comtech’s future roadmap is the company’s ‘Insights at the Edge’ concept, which is designed to fuse SATCOM capabilities with geospatial intelligence. Comtech’s Insights at the Edge offering will ensure multi-dimensional and powerful new actionable intelligence is delivered to those who need it most through the ‘convergence’ of multi-orbit, multi-frequency and multi-modality capabilities, Daniel said.

“These and other compelling modalities have made rapid access to intelligence a new reality for the end user, creating patterns which can be generated when people, places and activities are correlated together,” he said.

Comtech is also focused on ensuring communications networks remain protected against cyber-attacks with Daniel explaining how cyber has become progressively more important over the last couple of years.

“Cyber has really been brought to the front of mind by some of the recent events we have seen. It can’t be added as an overlay after the fact, so it needs to be designed at the front end of a solution’s lifecycle,” said Daniel. “This is something we’re really focused on at Comtech—ensuring our solutions are designed to be cyber secure today, but also enabling those solutions to easily adapt, update and grow with a changing landscape.”

“It’s interesting to see just how long military customers leave equipment in the field and continue to have it operate well into the future. The cyber landscape that you see today is totally different to what we saw 10 years ago, so the importance of software-defined and field upgradeable cyber security is absolutely critical in giving customers the ability to stay current with modern threats without the need to send hardware back – because logistically, they can’t afford to.”

Comtech is also exploring Artificial Intelligence/Machine Learning (AI/ML) cyber related services for DoD customers which Daniel believes will be crucial in supporting the needs of CJADC2 moving forward, particularly at the tactical edge where risk of cognitive overload can be high.

“AI/ML capability becomes a really interesting opportunity where, for each advancement in automation, cyber-attacks and threat vectors, there’s a corresponding need for cyber defenses to incorporate AI/ML to automatically adapt capability to a changing landscape,” said Daniel. “We see that as an interesting challenge for satellite systems fielded 10-20 years ago which don’t necessarily have the compute power or other capabilities that you might want to have based on what we understand today. So we’re finding ways to partner with AI/ML leaders to field integrated solutions in the short term as we build this into our portfolio.”

Supporting Ukraine

Finally, Daniel described how the DoD’s ongoing support of the Ukrainian Armed Forces (UAF) continued to highlight the importance of rapid prototyping and fielding of technologies.

The desire of the UAF to field “70% capable, fit-for-purpose” technologies had “turned on its head” conventional wisdom regarding what warfighting technology should look like today, he said.

“This kind of approach makes it more affordable to field technology without going through an extensive qualification process which a lot of larger governments tend to wrap around any new equipment they want to field,” said Daniel.

“That kind of entrepreneurial approach is definitely something that we’ve adopted at Comtech,” said Daniel “So we’re looking to cut out as much of that non-value add process and get capabilities fielded that can be evaluated by end users and evolve over time to meet emerging needs in the field.”

Ultimately, according to Daniel, Comtech is leveraging its differentiated expertise across global commercial and government markets, unique culture of innovation, and close collaboration with DoD customers to not only solve their toughest challenges today, but also address those over the horizon.

Comtech’s extensive portfolio of defense and security technologies, systems, and services are designed to deliver the integrated smart networking capabilities needed to enhance CJADC2 operations. Comtech has extensive experience developing and deploying customized, interoperable, robust, and resilient systems and services for all branches of the U.S. Department of Defense, as well as coalition forces.

Imagine the challenge of setting up communication links in areas, where tall buildings, bridges, mountains, and various structures obstruct direct line-of-sight between transmitting and receiving stations. Traditionally, long-distance communication systems known as Troposcatter transmission were used in remote and harsh environments. But now, thanks to advancements in smaller next generation Troposcatter technologies, like those developed by Comtech, this technology can be applied for shorter distance communication links in a wide range of scenarios.

In environments, distances ranging from 1 to 10 kilometers often require communication over Obstructed Line-of-Sight (OLOS) links. The cityscape, battlefield, disaster scenario, and rural communities are filled with buildings, vegetation, vehicles, signs, and power cables that reflect radio signals, causing them to take multiple and unpredictable paths to reach their destination.

These geographic challenges presented a new opportunity for innovation, and Comtech saw it in the troposphere, the lowest portion of the atmosphere located about 8 to 15 kilometers above the Earth’s surface. Comtech’s Troposcatter Family of Systems (FoS) enable communications beyond the horizon. Radio signals travel through this layer of the atmosphere through forward scatter, where irregularities in the atmosphere’s refractive index create multiple radio paths, known as multipath transmission.

Dealing with multipath transmission can be challenging due to transmission delays over different signal paths and something called Short-term fading. This phenomenon results in rapid and deep changes in the signal level, making it tricky to maintain stable connection, especially when signals traverse over short time intervals (millisecond periods) with changes as significant as 40dB.

Comtech’s next generation Troposcatter FoS addresses the complexities of OLOS environments by combining multipath signals and mitigating short-term fading using diversity combining receivers. This unique configuration, known as the diversity system, allows Comtech to combine two or more independent signals received from various transmission paths. By doing so they increase the signal-to-noise ratio (SNR), resulting in a more reliable and stable SNR. This means a reduced likelihood of the combined signals’ quality falling below the minimum threshold needed for proper reception. The System also compensates for the time delays that signals experience while taking different independent paths between transmitting and receiving stations.

As the leading provider of Troposcatter systems, Comtech’s next generation Troposcatter FoS allow military operators and other end users to deliver vital information hundreds of miles over the horizon, or beyond-line-of-sight (BLOS), by bouncing microwave radio signals off the upper layers of the troposphere. Today, Comtech’s next generation Troposcatter FoS are delivering performance enhancements that represent a one-thousand-fold increase over former generations of Troposcatter systems.

Comtech’s portfolio of defense and security technologies, including the company’s Troposcatter FoS, are uniquely positioned to deliver capabilities that will enhance Combined Joint All Domain Command and Control (CJADC2) operations.

Comtech’s Troposcatter Family of Systems (FoS) has proven to be a robust and flexible platform to effectively deliver Beyond-Line-of-Sight (BLOS) high capacity, backhaul, communications in a wide range of environments. The Troposcatter FoS consists of multiple terminals that range in size from large scale transit case based transportable systems to small form-factor systems that can be easily flown anywhere in the world in airline checkable cases. Larger terminals in the Tropscatter FoS are currently deployed in widespread geographic locations to provide 50 to 100 Mbps of throughput at BLOS distances in excess of 100 plus nautical miles. For shorter distance requirements, the smallest terminal in the Troposcatter FoS can be paired with Active Electronically Steered Array (AESA) antennas.

In a recent demonstration, Comtech and Spectra Group proved that our Troposcatter Family of Systems (FoS) can provide effective Communications-On-the-Move (COTM) capabilities at ranges and throughput values typically associated with fixed emplacement communications systems. This demonstration illustrated that Comtech’s Troposcatter FoS can now be paired with advanced antenna systems that provide automatic pointing and tracking capabilities that enable fixed-to-mobile platform and mobile-to-mobile platform communications.

AESA antennas utilize beamforming and software-based electronic steering to give our systems the ability to find and track each other whether the systems are stationary or moving. Pairing the smaller terminals with AESA antennas significantly reduces the moving parts of the system, lowers power consumption compared to mechanical tracking systems, and eliminates the need for human intervention for antenna pointing and link acquisition. The small size and weight of the terminal and AESA combination allows the system to be easily integrated into land vehicles and installed in cramped quarters aboard sea-faring vessels; all while providing multi-MBPS throughput out to distances of 70 miles or more. Comtech has showed that this type of system could provide 87 Mbps of throughput at 40 miles in Sea State 4 conditions. Through multiple successful Troposcatter FoS capabilities demonstrations, Comtech and Spectra Group have been able to show the value of On-the-Move, Over-the-Horizon communications for commercial and government customers operations across a wide range of land and maritime environments to illustrate the benefits of bringing high-capacity communications to the tactical edge. Regardless of ground obstructions or sea states, the Comtech Troposcatter COTM member of the FoS can be counted on to extend critical voice, video, and data services to forward mobile elements with throughput values typically associated with fixed terminals.

Radio frequency relay link systems were invented in the late 1800s, and later adopted by militaries during World War II (WWII) to strategically communicate mission plans through audio messages. While the technology dates to WWII, military branches continue to rely on multiple LOS systems to relay critical information during missions. Today, relay links are limited in their ability to reliably deliver critical information when it’s needed most—whether it’s on a battlefield or during a natural disaster.

Comtech’s Troposcatter FoS can deliver reliable communications regardless of terrain geographic obstacles. Comtech’s smallest form factor Troposcatter solution, is optimized for enhanced, assured, lower power, all domain communications up to 60 kilometers.

Comtech’s portfolio of defense and security technologies, including the company’s Troposcatter FoS, are uniquely positioned to deliver capabilities that will enhance Combined Joint All Domain Command and Control (CJADC2) operations.
