Operate on the full ITU Ka-band spectrum to increase data rates to and from the aircraft

With a strong history of outfitting industry leading Ku-band terminals to a wide variety of aircraft, we are proud to deliver the next generation of Ka-band SATCOM terminals that operate over military and commercial networks. These mature terminals provide key communications for critical missions, including:

  • Real-time ISR with sensor & data streaming from the aircraft in theater to command authorities beyond the horizon
  • Search and rescue (SAR) missions for live “eye-in-the-sky” support
  • Anti-piracy and maritime interdiction
  • Enroute command and control (C2) and VIP transport communications


Mission-ready Ka-band terminals with network flexibility

Viasat Ka-band terminals are comprised of a small Ka-band antenna, our next-generation modem, and an antenna control unit integrated into the existing aircraft’s network. They are designed for flexible operation across both military, commercial, and Viasat’s constellation of high-capacity Ka-band satellites.

Elevate terminal capabilities with Viasat mobile service

Pair our Best Available Network (BAN) with our Ka airborne terminals to enable aircraft of all sizes to stay connected no matter where their mission takes them.  From a single platform to simultaneous operations (SIMOPS), Viasat is able to set-up service globally with enough capacity to serve multiple platforms in a region. In addition, Viasat offers the ability to tailor and customize your plan based on mission requirements. With a Viasat Ka-band terminal and our high-capacity SATCOM service, warfighters can stay connected, from base to objective.
