1. A method for detecting Global Navigation Satellite System (GNSS) error, comprising:
receiving, at a mobile device, one or more global navigation satellite system (GNSS) signals via a GNSS antenna of the mobile device;
determining first movement data based on the one or more GNSS signals;
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 a GNSS error occurs based on a determination that a difference between the first movement data and the second movement data exceeds a threshold, wherein the first movement data, the second movement data, or both, comprise data indicative of an acceleration of the mobile device, a velocity of the mobile device, a rotation of the mobile device, or a combination thereof.
