Viasat terminals– One SATCOM system for every mission & application

Whether sailors are communicating with family back home or relaying tactical information within the fleet, Viasat’s maritime terminals and high-capacity satellite service delivers exceptional connectivity at sea.  With Viasat, ships no longer need two separate networks for mission-critical communications and personal/MWR communications. Now ships can leverage the same high-capacity network for both applications through the ability to partition and secure the transfer of data.

Maritime SATCOM terminals

Viasat has a range of maritime terminals available for vessels small to large, including the new Global Maritime Terminal-6524 (GMT-6524) and Global Maritime Terminal-6514 (GMT-6514) -  Ku/Ka multi-band terminals with electronic band select that can operate in both single or dual antenna configurations.

One network with game-changing capabilities

When Viasat terminals are paired with our Hybrid Adaptive Network (HAN), ships of any size can remain securely connected around the globe. Our industry-leading data rates support multiple simultaneous ship sensors and amplify maritime missions & applications, including:

  • Search and Rescue (SAR)
  • Autonomous or Unmanned Surface Vessels
  • Maritime interdiction
  • C4ISR
  • Morale, Welfare & Recreation (MWR)
