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 military vehicles including HMMWV, Bradley and Stryker. The Model 17-17A series are configured to enable an aircraft integrator, with certified radome equipment, to install, test and qualify the terminal for airborne use. While certain users have operated the terminal on-board a variety of government aircraft platforms, the M17-17A series design is not by itself designed to meet stringent DO-160 airworthiness requirements.

This series of terminals shares a common technology base, components and user interface with the ground-centric 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.
