SATCOM On-The-Move Model 17-17A Airborne Terminals

General Dynamics’ SATCOM-on-the-Move (SOTM) Model 17-17A series terminals provide proven, high data rate, reliable X or Ku satellite communications while on-the-move. Leveraging a combination of integral tracking receiver, gyro stabilization, and inertial measurement unit, SOTM terminals provide vital access to voice, video and data in areas where terrestrial communication systems such as cellular, cable and radio have been damaged, overwhelmed or simply don’t exist. And while these terminals are sensitive enough to accurately receive satellite communications, they are also rugged enough to perform in the most challenging environments.

  • Reliable high data rate satellite communications while on-the-move
  • Interchangeable X and KU band payloads
  • Modem Agnostic
  • Lightweight and rugged to withstand the harshest environment

 

Features

SOTM terminals are available in a variety of sizes and configurations and have a long history of proven, reliable performance on aircraft, ships, fast boats and a variety of wheeled and tracked vehicles including HMMWV, Bradley and Stryker. The Model 17-17A series are designed specifically for airborne applications and share a common technology base, components and user interface with other products in the SOTM family (Models 20, 24 and 30).

  • Reliable high data rate satellite communications
  • Superior link availability and performance over a wide range of operational conditions
  • Interchangeable RF payloads provide maximum operational flexibility, including Ku, and X-Band
  • Leverages a wide range of commercially available modem systems
  • Modular design enhances maintainability and minimizes life cycle cost
  • Lightweight, low profile design with all RF Components on Elevation Payload for high efficiency RF Tx/Rx.
  • Antenna includes the antenna positioner, servo controller, tracking receiver, block up and down-converters and high efficiency solid state power amplifier all contained on the pedestal with only interface for Power, Ethernet and L-Band Tx/Rx interface to Modem.
