I SO 9 0 0 1 GSG-54 GPS 8-channel Simulator • Versatile 8-channel GPS signal generator with pre-confi gured test scenarios • Easy-to-use and intuitive • Fully operational via front-panel • Multiple interfaces for remote control • Stand-alone, compact and portable bench-top chassis • 3GPP A-GPS Standards-based testing • Affordable and powerful The GSG-54 is a GPS Constellation Simulator that expands on the features available with the GSG-L1 one-channel GPS signal generator without the complexity and cost of other multi-channel GPS simulators. The GSG-54 provides a wide-range of capabilities for in-line production testing, including navigational fi x and position testing, while offering ease-of-operation and extremely fast test cycles. It also benefi ts engineering and development organizations for integrating GPS receivers into their devices. Easy to Use The easy-to-use GSG-54 is an 8-channel GPS constellation simulator. The user can confi gure scenarios on-the-fl y without the need for external PC and without pre-compilation phase. Using the front panel the user can swiftly modify parameters such as user position and time and can defi ne the scenario through a set of predefi ned antenna and atmospheric models, as well as trajectories and events. Flexibility GSG-54 comes with built-in support for multipath simulation and a set of trajectories (static, circles, rectangular according to 3GPP TS 25.171) and allows the user to upload their own trajectories in NMEA standard format. The user can upload their own ephemeris data in standard RINEX format or re-use the default data for any time periods. GSG-54 can be controlled via a network connection over Ethernet. A USB and GPIB interface is also available. Suitable for Testing Timing Receivers Besides the variety of built-in navigation/positioning tests, the GSG-54 is also suited for accurate testing of timing GPS-receivers. The GSG-54 can be equipped with an ultra-high-stability OCXO timebase for precision timing of the satellite data, and to emulate the actual atomic clocks in the satellites, there is an input for external synchronization from a 10 MHz reference from e.g. a Cesium or Rubidium clock. A built-in 1-pps output, which is synchronized to the generated satellite data, allows comparison with the 1-pps signal from the timing receiver under test. The Affordable Test Solution The GSG-54 is a perfect fi t for a wide-variety of test cases including: „hƒnTest of simulated movements (user trajectories). „hƒnTest of receivers’ sensitivity to loss of satellites, multi-path, and atmospheric conditions. „hƒnFast production test of connectivity and sensitivity (conducted or over-the-air). „hƒnProduction test of positioning receivers accuracy. „hƒnTest of timing receiver accuracy. „hƒnTest of receivers’ dynamic range.
