Features

Key to the performance of any SOTM product is the availability to maintain the link during dynamic platform motion. General Dynamics SOTM products provide world-class “on satellite” tracking accuracy via combination of integral tracking receiver, gyro stabilization, and inertial measurement unit.

General Dynamics’ Model 24-30 series terminals provide high data rate, reliable Ku, or Ka Mil and Commercial band satellite communications while on-the-move over a wide range of operational conditions, and can be ordered with an Inertial Measurement Unit. The modular design of the terminal allows it to be customized to meet specific customer requirements.

  • 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, Ka MIL and Ka Commercial
  • The RF payload interchange can be accomplished in less than 15 minutes after radome is removed.
  • 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 interface for Power, Ethernet and L-Band Tx/Rx interface to Modem
