SPIRENT GSS4100 GPA/SBAS signal generator | Spolen

Brand: SPIRENT

The GSS4100 GPS/SBAS simulator is a comprehensive low-cost single channel RF generator for testing satellite navigation equipment in manufacturing, laboratory and field environments.
GSS4100 can generate GPS L1 C/A code signal or space augmentation system (SBAS) based signal (WAAS/EGNOS/MSAS).
The standard IEEE-488 (GPIB) and USB interface provide a mechanism to integrate the GSS4100 into the user test environment. GSS4100 also supports synchronization with other systems through its 1PPS/trigger, frequency standard input and 1PPS output.
The GSS4100 provides control over all aspects of the generated signal, including PRN, power level, Doppler, analog time, and signal/message content. This function can be called in an independent interactive mode by using SimCHAN software provided randomly for Microsoft Windows operating system, or in a fully integrated ATE mode through GPIB control interface.
Typical applications include GPS and wireless positioning production test ATE, error analysis, parameter evaluation and prototype transmitter.
