THIS REPORT EXAMINES THE FEASIBILITY AND IDENTIFIES POTENTIAL PROBLEM AREAS OF TWO DIFFERENT AUTOMATED VEHICLE LOCATION SYSTEMS.

Abstract

IT WAS FOUND THAT THE CONCEPT OF HYBRID DEAD RECKONING, USING INERTIAL COMPONENTS, IS TECHNICALLY FEASIBLE BUT THAT THE ANNUAL MAINTENANCE COSTS OF CURRENTLY AVAILABLE DIRECTIONAL GYROSCOPES PRECLUDE ITS USE BY THE TRUCKING INDUSTRY. THE OTHER SYSTEM TESTED, HYPERBOLIC GRID LOCATION, USES PHASE-LOCKED SIGNALS FROM COMMERICAL AM (AMPLITUDE MODULATION) BROADCASTING STATIONS. FOR VEHICLE LOCATION PURPOSES, THIS WAS FOUND TO BE TECHNICALLY SOUND, AND IMPLEMENTATION COSTS ARE WITHIN THE BOUNDS ESTABLISHED FOR THE CARGO SECURITY SYSTEM.
