The VIAVI GC-130 GPS Antenna Coupler provides >20 dB of antenna isolation, ensuring outside GPS signals are not seen by the aircraft’s GPS receiver when simulating a user defined GPS signal. The coupler mounts directly over the aircraft’s GPS antenna.

The GC-130 is designed for use with the VIAVI GPSG-1000 GPS Simulator when the supplied antenna coupler is too small to accommodate the GPS antenna of the system under test.

Benefits: 

• Reliable GPS simulation in hangars and other low coverage areas
• When used with the GPSG-1000 GPS Simulator:
• Almanac and TOD update when no outside GPS signal is available
• Sensitivity testing of the GPS system
• Dynamic GPS simulation to simulate aircraft movement for testing of other aircraft systems
• Determine latency of the GPS and transponder systems

Key Features:

• Provides >20 dB of antenna isolation
• <1 dB repeatability
• Supports GPS antennas up to 14 inches in diameter
• Rugged design for ramp use

Included in kit:

• GC-130 GPS Antenna Coupler
• Rigid transit case
• Coax cable, 20 ft. TNC
