Abstract
A test system for performing over the air testing on a device under test (DUT) with satellite navigation system capability is provided. The test system may include a test host, a satellite navigation system emulator, a test chamber in which the DUT may be placed during testing, and test antennas mounted inside the test chamber. The satellite navigation system emulator may receive ephemeris and almanac data and may generate corresponding simulated test signals to be transmitted to the DUT via the test antennas. The test antennas may be mounted on fixed or rotatable ring-shaped antenna mounting structures configured to emulate respective orbital planes in a given satellite constellation that is currently being characterized. The DUT may also be rotated during testing to emulate user movement.
