1. A vehicle comprising an odometry system, the odometry system including:
a plurality of sensors; and
one or more controllers collectively programmed to execute the following instructions:
estimate odometry of the vehicle based on sensor data from the plurality of sensors, to produce a plurality of odometry estimates;
monitor integrity of one or more of the plurality of sensors;
correct sensor data from one or more of the plurality of sensors to provide corrected sensor data;
compensate the corrected sensor data to provide compensated data; and
use the compensated data to provide at least one of vehicle odometry, vehicle states, and time stamp information;
wherein the instruction to compensate the corrected sensor data further includes an instruction to adjust an external position origin of the vehicle provided by the one or more controllers to external users of the vehicle odometry.
