SATCOM On-The-Move Model 20-24M Terminal
The M20-24M SATCOM On-The-Move Antenna was specifically designed for ground vehicle command, control and communications (C3) missions where beyond line of sight (BLOS) SATCOM capabilities are mission critical. Key to the performance of any SOTM product is the ability to maintain the link during dynamic platform motion. SATCOM On-The-Move products provide world class “on satellite” tracking accuracy via a combination of integrated tracking receiver and high-bandwidth line-of-sight stabilization.
Reliable high data rate satellite communications while on-the-move
Interchangeable KU and KA band payloads
Modem Agnostic
Lightweight and rugged to withstand the harshest environments
Features
Key to the performance of any SOTM product is the ability to maintain the link during dynamic platform motion. SATCOM-on-the-Move products provide world- class “on satellite” tracking accuracy via a combination of integrated tracking receiver and high-bandwidth line-of-sight stabilization. The modular design of the terminal leverages a common gimbal with band-swappable certified RF payloads enabling frequency band changeover within 5 minutes.
- Reliable high data rate satellite communications
- Superior link availability and performance over a wide range of operational conditions
- RF bands provide maximum operational flexibility, including Ku and Ka MIL 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 houses the antenna positioner, servo controller, tracking receiver, and complete suite of RF components
- Antenna interface includes +28VDC power, data (Ethernet), navigation, and L-Band Tx/Rx (To Modem)
