The GSS4100 GPS/SBAS Simulator is a complete, low-cost Single-Channel RF generator for testing satellite navigation equipment, especially in a manufacturing environment, in the laboratory or in the field. The GSS4100 generates either a GPS L1 C/A code signal or a Space Based Augmentation System (SBAS) signal (WAAS/EGNOS/MSAS). Standard IEEE-488 (GPIB) and USB interfaces provide the mechanism for integrating the GSS4100 into a user’s test environment. The GSS4100 also supports synchronization to other systems via its 1PPS / Trigger and Frequency Standard inputs and its 1PPS output.
