1. A computer-implemented method of mitigating global positioning system (GPS) inaccuracy, the method comprising:
identifying a required level of location accuracy for an activity of an autonomous system;
determining, according to GPS coordinates, a location of the autonomous system;
determining, according to a knowledge base created by continuous historical machine learning, whether GPS location accuracy at the location of the autonomous systems meets the required level of location accuracy for the activity of the autonomous system;
responsive to a determination that the GPS location accuracy at the location of the autonomous system does not meet the required level of location accuracy for the activity of the autonomous system, handing off location determination function to an installed infrastructure within a defined proximity of the autonomous system, wherein the installed infrastructure is configured to provide the required level of location accuracy for the activity of the autonomous system; and
instructing the autonomous system to perform the activity according to location information provided by the installed infrastructure.
