Satellite Communications Modems

satTRAC Modems provide RF conversion and modem processing for TT&C and Payload links with support for all commonly used frequencies and waveforms.

satTRAC Modems offer extensive configurability, resiliency, and security; they are compatibility tested with most GEO spacecraft buses and LEO smallsat radios.

An ethernet-attached RF digitizer connects to the modem’s software application running on commercial servers.

  • Digitizer technology conditions, filters, downconverts, samples, and decimates to a digitized IF over Ethernet
  • The modem’s intelligence is the satTRAC App software that performs all demodulation, modulation, and ranging computations
  • TRL 9, proven in both factory compatibility tests and on-orbit operations
  • 5 Mbps Commanding Uplink
    10 Mbps Telemetry Downlink
    180 Mbps Payload Downlink
  • Server or Cloud Hosted
  • Custom Configurations
