Claim 10:
11. A tangible non-transitory computer readable storage media impressed with computer program instructions that, when executed, test an autonomous vehicle, including
shielding a Global Navigation Satellite System (abbreviated GNSS) receiving antenna of the autonomous vehicle from ambient GNSS signals while the autonomous vehicle is under test and supplanting the ambient GNSS signals with simulated GNSS signals;
using a GNSS signal generating system,
receiving the ambient GNSS signals using an antenna of the GNSS signal generating system and determining a location and acceleration of the autonomous vehicle from the ambient GNSS signals;
accessing a model of an augmented environment that includes at least multi-pathing and obscuration of the ambient GNSS signals along a test path, based on the location determined from the GNSS signals;
generating the simulated GNSS signals to feed to the autonomous vehicle, in real time, simulating at least one constellation of GNSS satellite sources modified according to the augmented environment, based on the location determined from the GNSS signals; and
feeding the simulated GNSS signals to a receiver in the autonomous vehicle, thereby supplanting ambient GNSS as the autonomous vehicle travels along the test path.
