Spectra Group Launches New Troposcatter on the Move (TOTM) Capability at SOF Week

Friday, May 2nd, 2025

Spectra Group, a specialist provider of secure voice, data and satellite communications systems, has developed in partnership with BATS Wireless antennas a new capability enhancement for Comtech Telecommunications Corp. (Comtech) Troposcatter 10-Watt Compact Over-the-Horizon Mobile Expeditionary Terminals (COMET) called Troposcatter on the Move (TOTM). Since 2024, Spectra Group has global distribution rights for Comtech’s Troposcatter Family of Systems (less the USA, Canada and Mexico which Comtech retains). They have been working in partnership with Comtech and BATS Wireless antennas throughout 2024 to develop the TOTM concept, for which, as the systems integrator Spectra Group has full distribution rights. Spectra Group are launching this new TOTM capability at SOF Week and will be showcasing this and their other strategic communication capabilities in Booth #1805.

The use of the troposphere for communications is not new, but in the past, it was constrained by large dishes and significant power that was not suitable for modern manoeuvre warfare. Comtech’s COMET system revolutionised this capability making it small, lightweight and portable. The COMET system is ideal for providing a secure big data network for deployed headquarters from divisional down to company level or below because it is small, lightweight and due to its low power and directional nature it is also extremely difficult to detect and deny. Critically, it is also satellite independent, can work in a GPS/GNSS denied environment and is proven in the polar regions making it ideal for use during global peer-on-peer conflict and when multi-domain integration is required. However, in the past it did need to be static.

Comtech and Spectra Group recognised the need for increased manoeuvre and large network data on the move, and so, working together with BATS wireless proved the concept of TOTM. Subsequently, Spectra Group working in partnership with BATS Wireless has produced a fully integrated TOTM solution that combines Comtech’s COMET troposcatter with BATS Electronically Steered Antennas (ESAs) into a single fully integrated terminal to deliver an industry first capability. Extensive sea trials successfully tested and validated TOTM scenarios by simulating island hopping in the Florida Keys, Florida Panhandle and off the coast of California. The tests involved ship to shore and ship to ship scenarios proving the concept of TOTM by demonstrating systems tracking and communicating with other nodes while on the move using GPS, but also showcasing the potential for advanced mobile connectivity in challenging environments without reliance on GPS.

TOTM enhances the utility and operational effectiveness of COMET in a littoral manoeuvre context, especially in contested, GPS or satellite denied environments. Its mobility and capacity delivers band- widths of up to 210 Mbps and ranges in excess of 100 Km to support a wide range of mobile applications such as Ship to Ship or Ship to Shore communications, Beyond Line of Sight strategic communications or Wide Area Networks, secure data links for autonomous sensors, control of remote vessels, Intelligence Surveillance and Reconnaissance (ISR) and any other application that requires big data delivered to the front line. The TOTM solution can also be utilized with land vehicles for efficient “at the pause” applications, enabling users to quickly establish Troposcatter communications without having to set up and align antennas, allowing rapid data transmission from positions of opportunity.

Simon Davies, CEO of Spectra Group said: “We pride ourselves at Spectra Group on being able to work in partnership with industry leaders to push the boundaries of what can be achieved using the latest technology to meet the demands of regular and specialist forces in the ever-evolving battlespace.

Our trials have successfully proved the Troposcatter on the Move capability which is a significant enhancement to the existing Troposcatter COMETs utility, especially in the littoral manoeuvre space, and superbly complements the Troposcatter Family of Systems and our award-winning SlingShotTM radio and new GENSS platform which also enables BLOS and COTM for troops deployed in austere locations globally.”

Spectra Group Train Armed Forces of the Philippines (AFP) to Use Troposcatter MTTS

Sunday, March 23rd, 2025

Spectra Group (UK) Ltd, a specialist provider of secure voice, data and satellite communications systems, has been supporting the Armed Forces of the Philippines (AFP) to enhance their strategic communications expertise, particularly by maximising the capabilities and hence benefits of using Comtech’s Troposcatter Modular Transportable Transmission System (MTTS).

Spectra Group acquired the global distribution rights for Comtech’s Troposcatter Family of Systems (less USA, Canada and Mexico which is retained by Comtech) in 2024 and late last year Spectra Group also announced opening their Australia office to better support the Asia region.

Tropospheric scatter is a communications capability that uses the Troposphere (up to about 13km altitude) to provide high bandwidth communications. It is satellite independent and works in a GPS/GNSS denied environment, so is suitable for use in a Peer-on-Peer conflict/Multi Domain Integration. Troposcatter inherently has very low latency and can provide huge bandwidth, potentially enabling analysis and manipulation of large data, which combined with its low operating cost makes it suitable for strategic down to tactical headquarters. Troposcatter MTTS is the most flexible, rapidly deployable, modular transit case troposcatter system available for when the operational situation demands high power, typically 500W. Key benefits for the AFP include rapid deployability, exceptional mobility and robust performance in challenging environments, enabling critical voice, data, and video communications in situations where traditional infrastructure is unavailable.

Throughout March, Spectra Group has been providing a comprehensive familiarisation and training package to the AFP to ensure that they are not only able to unlock the full capability of their MTTS Troposcatter systems but also embed indigenous knowledge and expertise to maintain the capability for the future.

Shaun Barry, Business Development Manager at Spectra Group said: “We have been working hard over the last couple of years to develop opportunities in the Asia region and this training programme is a good example where we are directly supporting our customers to not only get the best from their equipment now but also sustain that capability into the future. The region is extremely geographically complex which presents multiple strategic communication challenges for security forces and Spectra Group has have a number of superb systems including Troposcatter, SlingShot and soon GENSS that provide the perfect solution to these challenges.”

Airbus U.S Space & Defense and Aerostar Expand Their Existing Collaboration with Contributions from Persistent Systems

Sunday, March 16th, 2025

Today, Airbus U.S. Space & Defense and Aerostar announced an expansion of their Cooperative Research and Development Agreement (CRADA) to include additional capabilities from Persistent Systems, LLC (“Persistent”).

This expansion culminated in the launch of a second joint Internal Research and Development (IRAD) stratospheric test flight that will enable continued testing of hardened communications systems. These can be used to support ISR sensor collection and network extension missions from the stratosphere, which both companies are working to operationalize. Aerostar offers a series of stratospheric High Altitude Balloon Systems and Airbus is leading the field of stratospheric fixed wing systems with its Zephyr HAPS (High Altitude Pseudo Satellite / High Altitude Platform Station).

Launched Feb. 6, 2025, from Sioux Falls, S.D., IRAD Flight HBAL717 is currently operating over the Pacific Ocean. This flight includes an Aerostar Thunderhead Stratospheric Balloon system, satellite communication terminals hardened by Airbus U.S. engineers, and Persistent’s networking system and over-the-horizon Cloud Relay™ technology.

“Each of our companies brings something special to the table and we’re united in the quest to operationalize the stratosphere in a complimentary fashion,” said Fabian Kluessendorf, Airbus U.S. UAS Engineering Director. “Ultimately, the goal of this flight is to test the integration, encryption, backhaul, and routing of ISR traffic to government cloud systems from anywhere on the globe. On top of this it will pave the way for trusted payload-automation using onboard AI/ML capabilities. Our technology will be tested and qualified for operations through a long-duration stratospheric flight.”

Prior to the flight, a cross functional team of engineers from all three companies worked together to rapidly prototype variants of their hardware for future stratospheric balloon or fixed-wing flights.

“Stratospheric platforms are the most cost-effective, long-duration, persistent flight vehicles in service today. Aerostar continues to invest R&D dollars into integrating warfighter-relevant end-to-end solutions for resilient communications and ISR collection in critical, contested theaters,” said Russ Van Der Werff, Aerostar’s VP of Stratospheric Solutions.

“Persistent Systems is proud to partner with Airbus and Aerostar to integrate, test, and deploy advanced network solutions in support of the Warfighter. By leveraging both our Cloud Relay technology and Wave Relay® mobile ad hoc network (MANET), our government end-users will gain enhanced ISR and network-extension capabilities,” said Tom Jennings, Director of Business Development at Persistent Systems. “The swift and effective collaboration between Airbus, Aerostar, and Persistent Systems underscores the commitment and agility of all stakeholders, and we are look forward to continued partnership and innovation.”
