COMSAT’s Thales MissionLink™ Terminal key DoD component
COMSAT has outlined their plans for the Thales MissionLINK terminal as an integral piece of the Department of Defense’s (DoD) network modernization architecture for vehicular and dis-mounted units in a Communications-On-The-Move (COTM) environment.
Iridium Certus presents DoD users with a unique capability to reach any number of their devices, platforms or personnel globally and simultaneously through one resilient, secure IP network.
Use cases for global broadcast services, netted user groups, tactical radio augmentation, machine-to-machine/IoT, C2 and C4ISR applications abound, asbIridium Certus is increasingly being recognized as an integral piece of the DoD architecture, as opposed to being a purely commercial augmentation.
Iridium Certus user terminals sign onto the network via a gateway located in the U.S. where all data and voice traffic lands and is seamlessly handed off to terrestrial circuits.
Depending on the user terminal’s location and average number of cross-linked satellite hops, the latency in any given connectivity session is as low as 100 milliseconds round trip, which is a substantial improvement when compared to geostationary systems.
This opens Iridium Certus up to a range of latency dependent enterprise applications like video conferencing and secure voice calls.
Leveraging Thales’ pedigree in “tacsat” and data link comms systems, their Iridium Certus Thales MissionLINK terminal enables the capability to create network level system interfaces to a number of existing DoD standards, building a secure SATCOM node into vehicular and dismounted comms kits.
COMSAT points out that beyond network performance differentiators, Iridium Certus’ RF links present a very low probability of intercept due to rapid data path transition between multiple cross-linked satellites that make up the Iridium NEXT LEO constellation.
This rapid path transition also presents strong benefits in terms of network resiliency as connections can be routed around any one satellite anomaly, something that simply isn’t feasible in a traditional geostationary or bent pipe network architecture.
ViaSat-2 satellite comms now available for government, defense and military use
Viasat Inc. (Nasdaq: VSAT) has announced the availability of ViaSat-2 satellite communications (SATCOM) service for government, defense and military applications.
The service leverages the advanced communications satellite, ViaSat-2, along with innovations in ground networking technologies, that will deliver significant performance advantages over any other commercial or U.S. Department of Defence (DoD)
In early March 2018, Viasat conducted a ViaSat-2 SATCOM system demonstration — attended by representatives from the U.S. armed forces — and showed a number of cloud-based government applications.
The speeds on the ViaSat-2 satellite system demonstrated the industry’s fastest broadband connections, exceeding 100 Mbps during the demonstration day.
The ViaSat-2 SATCOM system has the ability to:
• Transmit bandwidth-intensive, media-rich cloud applications: Fast data rates and more satellite capacity will enable 4K and HD video streaming to thousands of electronic devices simultaneously for greater operational capabilities at the tactical edge
• Conduct more simultaneous operations: Abundant capacity will enable warfighters to capture and send Intelligence, Surveillance, and Reconnaissance (ISR) sensor data; transmit live two-way video conferencing and Voice over Internet Protocol (VoIP) calls; as well as conduct Command and Control (C2) and Situational Awareness (SA) communications as prioritized traffic to many more platforms in a region
• Continue operating through an electromagnetic, terrestrial or cyber-attack: Resiliency is provided through the ViaSat-2 system’s exceptional anti-interferer performance, Viasat’s unique Satellite Access Node (SAN) gateway diversity, seamless satellite switching and assured pattern re-routing to operate through gateway failures, and through Viasat’s Active Cyber Defense, which automatically detects, mitigates and attributes Distributed Denial-of-Service (DDoS) attacks against the network’s infrastructure. The resilient nature of the Viasat network will enable mission-critical communication packets to be protected and distributed safely, even in highly contested combat environments
• Provide assured communications: Viasat’s Best Available Network concept provides a global, redundant system for military to access Viasat’s global Ku-band networks, its more advanced Ka-band networks, as well as the Wideband Global SATCOM (WGS) system. The Best Available Network allows terminals to roam across multiple networks to maximize resilience and collaboration for ground fixed, transportable, mobile, maritime and airborne platforms
The ViaSat-2 satellite system validates the performance advantages and capabilities of Viasat’s commercial SATCOM system today with a glimpse into the Company’s ViaSat-3 SATCOM system capabilities.
Viasat’s SATCOM network delivers more bandwidth and better resilience, redundancy and active cyber protection required to maximize operational performance in the contested environments military operations face during combat.
Ken Peterman, President, Government Systems, Viasat, said the company is proudly demonstrating emerging U.S. government concept of operations requiring bandwidth-intensive, cloud-connected military applications with our latest high-throughput commercial satellite, ViaSat-2.
He added that the innovations in the new ViaSat-2 satellite and network show that Viasat can dramatically improve operational capabilities for military missions. This SATCOM system is the first in the company’s series of ultra-high-capacity global satellite networks, which will enable superior reach, readiness, and resiliency for global military forces.

GATR’s TRAC antenna is positioned for widespread use
The Department of Defense (DoD) now has access to a portable antenna with tracking capability that can be deployed in places where these capabilities have been traditionally limited.
With support from the U.S. Air Force (USAF) Small Business Innovation Research/Small Business Technology Transfer Program and the Air Force Research Laboratory, Alabama-based GATR Technologies developed a version of its inflatable antenna that can follow moving targets.
Also known as GATR TRAC, the new antenna is relatively lightweight and has a low-stowage volume so it can be easily transported then quickly assembled.
Tracking antennas are used to communicate with satellites in non-geostationary orbits, as well as with other moving objects such
However, legacy systems require a rigid dish with heavy-duty structural support making them difficult to use in many situations.
GATR, which was acquired by Cubic Corp. in 2016, has already begun selling the new product to military and commercial customers.
Early SBIR/STTR support from multiple organizations — including the U.S. Air Force and Missile Defense Agency (MDA) — originally helped GATR to develop 1.2 meter, 2.4 meter, and 4.0 meter inflatable antennas to be anchored to the ground and fixed on communications satellites in geostationary orbit. The company has sold hundreds of these to the DoD.
With more recent support from the Air Force SBIR/STTR Commercialization Readiness Program and AFRL, the concept was refined to create the 2.4 meter GATR TRAC that features mechanical and electrical components in a ruggedized base with support arms that allow the antenna to track satellites moving across the sky.
To develop an inflatable tracking antenna, the company had to overcome the challenge of grasping a large flexible ball-shaped radome and pointing it accurately under varying weather conditions.
The design evolution included improving reliability, creating a simple user interface, and upgrading assembly and disassembly procedures.
GATR TRAC has been demonstrated to reliably track satellites in LEO and produce usable imagery as part of a deployable ground station. The unit also has the ability to track satellites in other types of orbits.
The product packs into four cases that can be checked as airline luggage or shipped by traditional package delivery services, which lowers its cost of use while providing greater overall flexibility to mission planning. Assembly takes approximately 30 minutes.
The company has already logged more than $2.2 million in sales of the new tracking antenna to the military, as well as a commercial customer that supports the DoD. With hundreds of projected smallsats in LEO that will require tracking antennas, GATR TRAC is also well positioned for a potential boom in demand.
GATR’s recent successes — from its acquisition by Cubic to sales of its latest portable tracking antenna — are a critical benchmark for participants in the Air Force SBIR/STTR Program.
This type of commercialization helps to bring down costs and get technology to the warfighter while spurring the economy through small business growth.
Peter Ricci, an engineer with AFRL’s Information Directorate, said that the GATR TRAC system is a significant step forward over traditional satellite communication systems available today. It affords the user the ability to easily transport and set the system up in remote areas where it once was logistically impossible.
