Spirent STR4500 Multi-channel GPS Simulator Tube. Spectracom''s GPS Signal Generators are designed for high throughput production and manufacturing testing of GPS satellite signal receivers and their integration. The refraction is tantamount to a delay in the arrival of a GPS satellite's signal. SatGen v3 provides accurate and repeatable RF signals and is up to 3 times faster than previous versions. The CLAW simulator operates as a fully stand-alone simulator with multipath simulation capability, external real-time NMEA to GPS-RF transcoding capability, sub 5-ns UTC time-encoding accuracy. "Integrated Global Positioning System and Inertial Navigation Unit (GPS/INU) Simulator for Enhanced Traffic Safety," is a project awarded to Ohio State University to integrate different simulation models to accurately study the relationship between vehicle dynamics and roadway geometry. Having complete control over GPS signal generation is the only way to have confidence in your hardware and software's ability to perform - under any condition. Abstract: The development of the GPS (Global Positioning System) signal simulator involving to a number of key technologies, in which the generation of navigation message has important significance. The MATLAB signal simulation. I am in need of a GPS Simulator for use in a underground location where a GPS signal is required for the device to work.
