In early March Viasat demonstrated the capabilities of its ViaSat-2 satellite communications (SATCOM) system, showcasing its reach, readiness and resilience.

Announcing the availability of what the company terms “the world’s most advanced communications satellite” for government, security and military applications, Viasat believes that, combined with innovative ground networking technologies, the new service will deliver significant performance advantages over any other commercial or DoD SATCOM system. Speeds achieved during the demonstration exceeded 100 Mbps as a number of cloud-based government applications were trialled.

System capabilities bringing greater operational flexibility at the tactical edge include:
• Transmission of bandwidth-intensive, media-rich cloud applications: fast data rates and greater capacity will enable simultaneous streaming of 4K and HD video to thousands of users;
• Increased number of simultaneous operations: operators can capture and transmit ISR sensor data; transmit live two-way video conferencing and VoIP calls; conduct C2 and situational awareness communications as prioritised traffic to many more platforms than hitherto;
• Increased reliability: the resilient nature of the Viasat network will enable mission-critical communication packets to be protected and distributed safely, even in highly contested environments; unique gateway diversity, seamless satellite switching and assured pattern re-routing allow for operation through gateway failures and Viasat’s Active Cyber Defense automatically detects, mitigates and attributes Distributed Denial-of-Service attacks;
• Assurance: Viasat’s Best Available Network feature provides a global redundant system so that assured communications can be achieved. It allows terminals to roam across multiple networks, maximising resilience and collaboration for ground fixed, transportable, mobile, maritime and amphibious platforms.

“We are proudly demonstrating emerging US government concept of operations requiring bandwidth-intensive, cloud-connected military applications with our latest high-throughput commercial satellite, ViaSat-2. The innovations in the new ViaSat-2 satellite and network show that we can dramatically improve operational capabilities for military missions. This satcom system is the first in our series of ultra-high-capacity global satellite networks, which will enable superior reach, readiness, and resiliency for global military forces,” commented Viasat’s President, Government Systems, Ken Peterman.

ViaSat-2 gives operators a glimpse into the capabilities of the company’s next generation SATCOM system, unsurprisingly named Viasat-3.
