The General Dynamics SATCOM Technologies lightweight commercial 2.4-meter Trailer Mounted Satcom Terminal is designed for worldwide transmit and receive operation in C, X, Ku and Ka-band. This mobile terminal consists of a 2.4-meter tracking antenna mounted on a rugged chassis equipped with a generator and environmentally controlled rack enclosure. This configuration results in a low-weight tow package with superior features and high performance under wind-loading conditions. The accurate reflector surface provides exceptionally low sidelobe and cross-polarization performance well within INTELSAT and EUTELSAT requirements.

  • Full-featured auto-acquire tracking controller
  • Compact transit configuration for aircraft transit
  • Multiband antenna system with rapid interchange between C, X, Ku and Ku-band feeds
  • Motorized cable drive positioner
  • 38 RU Electronics Enclosure Unit (EEU)
  • 7.5 kW generator and 3 kW UPS

 

Product Details

Features

The interchangeable feeds are palletized for quick, easy removal and replacement, allowing the end-user to effectively change frequency bands in the field within minutes. HPAs can be boom mounted for minimal WG losses per the customer’s requirements. The onboard generator provides power to the UPS, ECU, and all the rack-mounted equipment located in the 38 rack-unit electronics enclosure. The entire terminal can be controlled through the M&C system as part of the 323T tracking controller (optional). The commercial 323T ACU provides auto-acquisition and several optional tracking algorithms including adaptive tracking in high winds.

  • Single offset carbon-fiber reflector
  • High performance
    • Low sidelobes, high EIRP capability, compliant under operational wind conditions
  • Stow/deployment
    • Low profile, stow position on vehicle, precision alignment, automatic deploy and stow
  • INTELSAT type approved for C/Ku-band, EUTELSAT compliant
  • Safety equipment, brakes, lights, pintle hitch

Options

  • Reflector (single or three-piece segmented)
  • Finishes (white or per customer spec)
  • Integration (various TWT/amplifier mounting arrangements)
  • Anti-icing
  • Troposcatter capable
