1. A method, comprising:
obtaining, by a process, a first location of an object from a primary location determination hardware system;
obtaining, by the process, a second location of the object from a secondary location determination hardware system;
determining, by the process, a distance difference between the first location and the second location;
determining, by the process, whether the distance difference between the first location and the second location is acceptable based on a threshold distance; and
initiating, by the process, one or more mitigation actions in response to the distance difference between the first location and the second location being unacceptable, wherein one of the one or more mitigation actions comprises switching from utilization of the primary location determination hardware system to the secondary location determination hardware system for geolocation of the object.
