Abstract
A system for determining location of an object including a Master Unit having an RF transceiver and adapted to measure distance to a Tag. The Master Unit has a first input from which it can derive its current position, transmits instructions to the Tag for movement in a predetermined direction, measures distance to the Tag after the movement in the predetermined direction, and determines position of the Tag after the movement in the predetermined direction. The Tag and Master Unit can include a compass, a pedometer, an accelerometer, a solid-state gyroscope, an altimeter inputs for determining its current position by the Master Unit. The Master Unit can optionally include a GPS receiver. The Tag movement does not have to follow the Master Unit's direction, but the Master Unit will still be able to determine the Tag location(s). The roles of the Master Unit and Tag can be reversed.
