Remote Sensing Systems

Tracking Antennas for LEO, MEO, and GEO from UHF to Ka-band

Viasat Antenna Systems designs, integrates, and delivers high-performance "RF to Archive" tracking antenna systems for the remote sensing, telemetry, data link, satellite TT&C, and satellite communications markets. Our ground systems support LEO, MEO, and GEO satellites from UHF to Ka-band. Spanning the globe from pole-to-pole, we have delivered over 150 commercial remote sensing antennas and upgrades in more locations than any other major manufacturer.

  • L-, S-, X-, Ku-, Ka- and multi-band data
  • High efficiency dual shaped reflectors for optimum G/T
  • Sizes from 3m to 13.56m that are used in both fixed and mobile remote sensing applications
  • Dual drive motors in each axis on all systems for reliability and backlash elimination
  • Synthesized up- and downconverters for full frequency band coverage
  • Full station automation using both UNIX and Windows platforms
  • Automated scheduler, with priority contention resolution for planning satellite pass data reception

 Viasat is ideally suited to provide a system tailored to meet specific customer requirements. 

  • High surface accuracy of reflectors enables for VLBI applications and superior remote sensing performance
  • S-band transmit capability for satellite uplink commands
  • High dynamics Elevation/Azimuth/Tilt, Elevation/Azimuth/Train and X/Y pedestals
  • Digitally implemented servo controls with optimal state model filtering for the ultimate in tracking accuracy
  • Low and high data rate demodulators and bit synchronizers (6-320 Mb/s), provide data reception capability for all known remote-sensing satellites
  • Built-in automated system tests for system troubleshooting and confidence
  • Fiber-optic interconnects available for systems where the control room and antenna are positioned distant to one another
