As demand for precision GPS receivers continues to grow through a number of industries and applications, increased attention to focused GPS receiver test can land you ahead of the competition.
For each of the many steps that a GPS receiver must go through in order to accurately provide position and timing information, errors are introduced. By testing each step in an isolated fashion and with controlled introduction of signal impairments, you can target your troubleshooting and invest in areas of the design that will offer the greatest returns. While a drive test may allow you the most realistic reproduction of the environment the GPS receiver will be found in, it offers little information about the specific impairments present in the signal or what you can do to improve your design.
With a GPS Simulator, you have full control over signal power levels, Doppler shifts, ephemeris errors, multi-path fading, ionospheric effects, and many other impairments found in real-world GPS signals. By simulating a GPS signal, you can introduce each of these impairments individually or in scenario-specific combinations for the targeted troubleshooting needed to truly improve your design.
