Viasat terminals – ground-breaking connectivity experience

At 45,000 feet, it is critical for aircraft to have connectivity. Viasat’s dual-band terminals continuously navigates between Ku- and Ka-band networks, delivering an industry leading SATCOM experience.

  • High-speed data rates and streaming video to everyone on board
  • Delivery of HD video streams off the aircraft 
  • Real-time transfer of aircraft operational data

GAT-5530 terminal

Our second-generation Ku/Ka-band terminal’s flexible architecture allows for operating over multiple networks and third-party modems. Enabling access across the full ITU Ka-band spectrum, the GAT-5530 multi-band, multi-network, multi-orbital terminal delivers the fastest data speeds while supporting multiple aircraft sensors.

The GAT-5530 terminal features the following details:

  • Antenna Type: Medium profile, waveguide horn array; fuselage mount
  • Equivalent Circular Diameter: 15 in.; 38 cm
  • Terminal Weight: 190.6 lb.; 86.45 kg
  • Terminal Power: 645 W

Dual-band solution

Our most recent dual-band solution is comprised of two independent 12 in. parabolic antennas, one operating over Ku-band and the other over Ka-band,  to create a low SWaP dual-band solution. Perfect for an aircraft with an existing Ku terminal that is looking to amplify its connectivity or for a smaller aircraft requiring seamless connectivity across dual networks.


Our dual-band antenna solution features the following details:

  • Antenna Type: Parabolic reflector; tail mount
  • Effective Size: 12 in.; 30.5 cm
  • Terminal Weight: 88.8 lb.; 40.3 kg
