GPS/SBAS Signal Generator GSS4100 Typical applications include GPS and Wireless Location Features production test ATE, fault analysis, parametric evaluation, The GSS4100 GPS/SBAS Simulator is a complete, low-cost and prototype transmitters. Single-Channel RF generator for testing satellite navigation equipment, especially in a manufacturing environment, in Highlights the laboratory or in the field. � Supports both GPS and SBAS signals in a single package The GSS4100 generates either a GPS L1 C/A code signal or � Full control over signal content and dynamics a Space Based Augmentation System (SBAS) signal � Integrated ATE and stand-alone instrument modes (WAAS/EGNOS/MSAS). � Fully user-definable data messages using SimCHAN Standard IEEE-488 (GPIB) and USB interfaces provide the software mechanism for integrating the GSS4100 into a user’s test � Stable and accurate all-digital FPGA architecture environment. The GSS4100 also supports synchronization � Industry-standard GPIB to other systems via its 1PPS / Trigger and Frequency (compatible with STR4775 product) Standard inputs and its 1PPS output. � Low cost � Rack mount kit available Control is provided over all aspects of the signal generated, including PRN, power level, Doppler, time of the simulation and signal/message content. This capability is accessed either in a stand-alone interactive mode, using the ® ® supplied SimCHAN software for Microsoft Windows via Spirent USB, or in a fully integrated ATE mode via the documented Communications GPIB control interface.
