System and method for testing real world A-GNSS performance of a device

A test device-implemented method for testing A-GNSS performance of a user equipment, the method including:

• capturing radio frequency signals from GNSS constellation satellites while following a route and logging correlated position truth data along the route from a GNSS tracker;
• replaying to a device under test (abbreviated DUT) the captured radio frequency signals while conducting an A-GNSS session with the DUT, including supplying to the DUT assistive position data generated from the correlated position truth data.

A test device-implemented method for testing a user equipment in a simulated A-GNSS environment, the method including:

• testing operational performance a device under test (abbreviated DUT) in laboratory by replaying to the DUT previously recorded GNSS signal spectrum captured during a drive along with supplying generated assistive position data that matches a vehicle trajectory captured during the drive.

A system for testing a user equipment in a simulated A-GNSS environment, the system including:

• a processor;
• code stored in memory coupled to the processor, which when executed on a processor:
• tests operational performance a device under test (abbreviated DUT) in laboratory by replaying to the DUT previously captured GNSS signal spectrum captured during a drive along with generated position assistive data that matches a vehicle trajectory captured during the drive.

An article of manufacture that includes non-transitory processor readable storage with processor executable code for testing A-GNSS performance of a user equipment, including:

• replaying to a device under test (abbreviated DUT) a recorded GNSS signal spectrum previously captured during a drive, which is correlated with position truth data that represents a true position of a GNSS receiver that captured the GNSS signal during the drive;
• and
• performing an A-GNSS session with DUT during the replaying, including generating assistive position data from the position truth data correlated with the replaying.
