Title:
SPOOFING DETECTION AND REJECTION
Document Type and Number:
WIPO Patent Application WO/2019/168571
Kind Code:
A3
Abstract:
Systems and methods for performing spoofing detection and rejection including receiving (602), at a Global Navigation Satellite System (GNSS) device having an antenna, a set of signals, identifying (604) a questionable signal in the set of signals, and in accordance with a determination that the set of signals includes a subset of valid GNSS satellite signals (620), where the subset satisfies a minimum number of valid GNSS satellite signals and does not include the questionable signal, calculating an approximate position of the GNSS device based on the subset of valid GNSS satellite signals.
