SYSTEM AND METHOD FOR TESTING REAL WORLD A-GNSS PERFORMANCE OF A DEVICE

摘要

The technology disclosed relates to implementing a novel-testing framework that combines playback of captured GNSS signals with real-time emulation of assisted global navigation satellite system telemetry (abbreviated A-GNSS) in a test session with a mobile device. In particular, it can be used for testing A-GNSS performance of communication devices, navigation systems, telematics and tracking applications.

主权项

1. A method for testing A-GNSS performance of a user equipment, the method 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 the DUT during the replaying, including generating assistive position data from the position truth data correlated with the replaying.
