GPS/GNSS Simulation Systems for Military, Defense & Government Applications
Spirent military GPS solutions are used extensively for R&D at the extremes of GPS performance, accuracy and resilience. We can simulate classified codes as well as high dynamics and interference environments
GPS solutions within a Military, Defense and Government environment have several issues in common: they need to be robust, reliable and accurate. But with differing geographies and applications, testing requirements are diverse and GPS/GNSS receiver performance testing needs to take these differences into account.
GPS SIMULATION TESTING IN THE LAB
Testing in the lab with a GPS simulator will eliminate problems, reduce program cost and lead to quicker deployment. Within the controlled laboratory environment, a wide variety of testing is possible. Test configurations include the simulated GPS/GNSS signals, simulated inertial sensor data and jamming and interference sources.* Remote motion data and hardware-in-the-loop configurations can also be readily supported.
*Approvals may be required for some configurations.
GPS SIMULATION TEST PLATFORMS
Spirent’s comprehensive range of flexible, industry-leading GPS test systems support all current and modernized GPS signals, including P(Y)-code, SAASM, AES M-code and SDS M-code. As the test set-up is directly under user control, and repeatable, testing is more efficient and device performance can be readily characterized and optimized, including under extreme and error conditions.
Spirent has sought and acquired the approval of the GPS Wing for our approach and architecture for modernized GPS testing. Spirent has also provided on-going co-operation on test programs e.g. recent SVN-49 issue proving and testing.
