The GPSdome-SunStone Single Band OEM is a robust, small-sized and lightweight non-enclosed OEM, single-band, 2-element GNSS anti-jamming module that keeps navigation and autonomous operations running in GNSS-challenged environments.

  • Protects one GNSS band, selectable from GPS L1/Galileo E1, GPS L2, GPS L5 or GLONASS G1
  • Optional passthrough of up to two additional unprotected GNSS bands
  • Optional direct path to a second receiver (unprotected)
  • Software-defined, field-upgradeable anti-jamming algorithms with null steering
  • Real-time jamming detection, status and power-level monitoring via UART
  • Compatible with modern and legacy GNSS receivers with a physical RF input
  • Non-enclosed module for integration into your own platform or housing
