Abstract
A proximity detection system for determining the distance between a vehicle and a navigation beacon by resolving the altitude angle between the beacon and the vehicle and determining the distance between them. The system then defines an optimum distance between the beacon and the vehicle and compares the determined distance and the optimum distance to establish any difference between them.
