Spirent GSS7735 Multi-channel GPS l1/l2 Production teSt SiMulation The Spirent GSS7735 is designed specifically for testing dual-frequency GPS equipment and sensors in manufacturing environments. The GSS7735 is a self contained unit and does not require a separate PC controller. The GSS7735 is a highly accurate, stable generator capable of Key Features exceptional fidelity and resolution. ¢ 4 channel simulation at GPS L1 and L2 . GPS L1 supports C/A and P Code The GSS7735 signal generator is controlled via an embedded controller . GPS L2 supports P Code running a flexible control package with interface via the touch sensitive screen or external keyboard (supplied). This package includes easy ¢ Embedded controller scenario definition for a single static position. ¢ User-defined variables The 4 channel GSS7735 provides a complete simulated RF environment for . Date/time production testing GPS receivers and/or sensors with the ability to create a . Position (fixed) 3-dimensional position solution. . Duration . Satellite power levels This means that users can test not only sensitivity but also parameters ¢ Nominal and high (+50dB) RF power levels such as time-to-fix and positioning accuracy. TM The GSS7735 may be operated remotely via Spirent’s SimREMOTE ¢ Simple utility provided for annual calibration capability allowing control over scenario selection, start, stop and signal power levels via Ethernet TCP/IP. Remote operation over IEEE-488 is ¢ Rack mountable also available.
