Abstract
Methods, systems, computer-readable media, and apparatuses for determining location are presented. One example method includes obtaining a route comprising an ordered set of waypoints; receiving an indication of traversal of the route beginning at a first waypoint and recording a time associated with the indication; determining location information and time information at a sampling rate; for each subsequent waypoint of the ordered set of waypoints: receiving a signal indicating arrival at a current waypoint of the ordered set of waypoints, determining a time and a ground truth associated with the signal, and determining error information associated with each determined location between the prior waypoint and the current waypoint; and providing the error information to a remote device.
