A method of providing a vehicle monitoring system for ensuring accurate vehicle
milleage readings. A comparison is made between velocity measurements from several
sources to detect unauthorized modifications made to a vehicle in an effort to
ensure accurate vehicle odometer readings. The vehicle velocity measured on-board
is compared with vehicle velocity data signals received from a remote satellite
system in light of an allowable tolerance. The system will detect changes in the
vehicle such as tire size or tampering with the vehicles on-board measurement devices.
The system may communicate out of tolerance conditions to the vehicle operator
and the fleet manager.
