【Descriptions】
The GIH4 serial GPS/GNSS Repeater kit is a far forward gps signal amplifier unit. It is a GPS booster for hangard. GPS and GNSS signal inside hangar. This is one of the indoor GPS coverage solutions from GEMS-Navigation.
The structure of an aircraft hangar can block the ingress of GNSS signals, making it impossible to test on-board navigation equipment without pushing the aircraft outside where it has a view of the sky. GIH4 is GNSS Inside Hangar repeater. GIH4 repeater system overcomes this physical barrier by transferring the outdoor signals to the interior of the hangar, which means all maintenance work can be carried out indoors. The GIH4 supports four antennas, each antenna can cover a radius of 25 meters, so a GIH4 system can do GNSS coverage for four areas at the same time.

The GIH4 solution supports Global Navigation Satellite Systems (GNSS) including Beidou,GPS,Glonass & Galileo.
High efficiency directional indoor re-transmitting antenna suitable for:
*Aircraft hangars;
*Border surveillance;
*Military bunkers.
