The GPS Indoor Testing Solution (GPS-ITS) comes with everything you need to build a complete re-radiating system that can re-radiate the GPS L1 signal indoors. The GPS L1 signal received by the roof antenna is amplified and re-radiated to GPS receivers indoors, eliminating the need to attach receivers directly to the roof antenna. The GPS-ITS consists of an active roof antenna, a passive re-radiating antenna, a roof antenna mount (L1RAMB), a re-radiating amplifier mount (WRUMT), 50ft of LMR400 cable, and a variable gain re-radiating amplifier (NVGLCDLA30RPDC) with an external power supply that powers the entire system. With 50ft of LMR400 low loss coax cable connecting the roof antenna to the re-radiating amplifier, the GPS-ITS will transmit the GPS signal indoors to receivers up to 200 feet away. In the standard Networked (Externally Powered) configuration, the re-radiating amplifier output (J1) is DC Blocked.

Use Cases

  • Re-radiates the L1 signal indoors for GPS product testing.
  • Saves time and money by keeping aircraft hangared during navigation system maintenance.
