GPS101 Signal Generator

Product Name: GPS Signal Generator

Brand: Aeroflex USA

Frequency Range: 1575.42 MHz

The IFR GPS-101 positioning system simulator offers **and continuous testing for positioning systems (GPS). The GPS-101 simulates a positioning satellite and generates a specific satellite vehicle (SV) and navigation data model to conduct this test. Along with remote loading of GPS almanac information and RF level/frequency control, the GPS-101 provides a portable testing solution for verifying GPS systems.

Basic Functions:

Verify the functioning of the installed satellite positioning system (GPS)

Quickly verify the GPS receiver's operational integrity

Optional Satellite Loader (SV) and Navigation (NAV) Data

The RF level is adjustable from -85dBm to -145dBm, with a 1dB step adjustment.

Doppler frequency shift control allows the operator to select a carrier frequency shift of approximately ±4kHz.

Utilize real-time clock to store GPS satellite almanac

Directly or via an antenna coupler connected to the receiver
