Abstract
A positioning and odometry system includes two or more vehicle beacons installed on an end of a vehicle and configured to communicate with one or more guideway beacons installed along a guideway. Processing circuitry is configured to communicate with the one or more vehicle beacons and perform at least one of: determine, before the processing circuitry enters a sleep state, a first vehicle position on the guideway; determine, after the processing circuitry wakes from the sleep state, a second vehicle position on the guideway; determine, after the processing circuitry wakes from the sleep state, any difference between the first vehicle position on the guideway and the second vehicle position on the guideway; determine a third vehicle position on the guideway using range measurements taken at configurable time intervals; and determine a vehicle speed where speed is measured as a change in the third vehicle position over time.
