GPS Networking’s Portable Re-Radiating Kit (PNRRKIT) is a re-radiating system that allows re-radiation of the GPS L1 signal indoors. The PNRRKIT consists of a re-radiating amplifier with a wall mount plug-in transformer that powers the entire system, and a passive L1 re-radiating antenna. The GPS L1 signal from the roof antenna is amplified and radiated indoors. Thus, if a receiver has line of sight with the re-radiating antenna, it can receive the GPS signal indoors up to 100 feet away.
