Record and replay in global navigation satellite system testing - EE Times

Record and replay in global navigation satellite system testing - EE Times

Customers at vehicle manufacturers and proving grounds need tests such as brake distance measurement to be accurate to 2cm. Before 2008, there were two options: live sky testing and simulation. Racelogic has always used live testing, which involves taking equipment out in vehicles on the road and around test tracks. This is useful for getting real world data, but the changing nature of satellite constellations means that no test can ever be repeated. The company’s development team also found constant testing in the field to be time and labor intensive. Therefore, for some tests we used an expensive artificial GPS simulator, which modeled the satellite signals modified with a user generated trajectory. However, the test engineers found that this didn’t sufficiently reproduce the real world environment. The results were not always a good indication of how their GPS products ...
