GSG-54 8-channel GPS Simulator
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 GPS Signal Simulator provides a wide-range of capabilities for in-line production testing, including navigational fix and position testing, while offering ease-of-operation and extremely fast test cycles. It also benefits 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 configure scenarios on-the-fly 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 define the scenario through a set of predefined antenna and atmospheric models, as well as trajectories and events.

Flexibility
GSG-54 Simulator 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 her own trajectories in NMEA standard format. The user can upload her own ephemeris data in standard RINEX format or re-use the default data for any time periods. The 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 GPS Simulator 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 fit for a wide-variety of test cases including:

Test of simulated movements (user trajectories).
Test of receivers’ sensitivity to loss of satellites, multi-path, and atmospheric conditions.
Fast production test of connectivity and sensitivity (conducted or over-the-air).
Production test of positioning receivers accuracy.
Test of timing receiver accuracy.
Test of receivers’ dynamic range.
