Abstract
Systems, methods, and devices for protecting against spoofing of Global Navigation Satellite System (GNSS) data are provided. An electronic device may include memory and one or more processors that execute instructions to cause operations to identify potential GNSS spoofing. The operations may include obtaining a first distance between a first GNSS receiver and a second GNSS receiver, obtaining first GNSS data indicating a first range measurement between a first GNSS satellite and the first GNSS receiver, obtaining second GNSS data indicating a second range measurement between the first GNSS satellite and the second GNSS receiver, and calculating a first expected range measurement between the second GNSS receiver and the first GNSS satellite based at least in part on the first distance and the first range measurement. Spoofing may be determined to have occurred based on a comparison between the first expected range measurement and the second range measurement.
