Abstract
A method and system for providing repeatable GPS performance testing of a communication device are provided. Navigation data is complied over a drive route. The navigation data is used as an input to a GPS simulator to duplicate in a laboratory setting the GPS signals present at the GPS receiver during a travel along the drive route. Performance data of a baseline unit can be obtained for benchmarking the performance of a communication device being tested. A device under test can also be exposed to simulated GPS signals and to both simulated GPS signals and other radio frequency signals, such as telephone network signals present along the drive route.
