GPS Testing for Integration & Verification Applications
How do you ensure flexibility, controllability and repeatability within a Systems Development test environment?
Integration and Verification testing presents the system developer with a range of test challenges. Exploring the performance envelope of a design requires flexible control of a wide range of parameters. Comparative testing used during regression testing or vendor evaluation requires the ability to exactly repeat a predetermined set of test conditions.
A constellation simulator provides levels of control and repeatability that can never be achieved using live-sky testing. A wide variety of parameters can be readily altered simulating control, space or user segment variables. Factors such as vehicle motion, satellite obscuration, atmospheric propagation, orbital constants and the navigation message are all under real-time user control making what-if trials easy when using a simulator.
User actions are recorded for subsequent playback making exact repetition of a test scenario a simple affair. Many receivers can be subjected to identical tests in the lab at the convenience of the user. Tests can be exactly repeated after a pause of weeks or months to confirm that development work has successfully addressed issues without affecting legacy performance.
