General Test Set : Aeroflex-IFR GPS101-2

IFR Aeroflex GPS-101-2 Global Positioning Simulator with the RF Antenna Coupler

The GPS-101-2 Global Positioning Simulator provides for installation and functional bench testing of global positioning system (GPS) receivers.

The GPS-101-2 simulates one of many specific global positioning satellites. Selected specific satellite vehicle (SV) signals transmitted with selected navigation (NAV) data test patterns are used to verify the operational integrity of GPS receivers.
