Abstract: Techniques disclosed herein are directed to detect the presence of false, incorrect, or spoofed Global Navigation Satellite Systems (GNSS) signals. Embodiments may comprise receiving, at a mobile device, a global navigation satellite system (GNSS) signal via a GNSS antenna of the mobile device; determining first movement data based on the GNSS signal; determining second movement data based on data from one or more motion sensors of the mobile device, wherein the first movement data and the second movement data each comprise respective movement-related information regarding the mobile device during a time period; and providing an indication that GNSS error is occurring based on a determination that a difference between first movement data and the second movement data exceeds a threshold.
