Abstract
A mobile tracking and positioning system includes a plurality of mobile transmit and receive stations that track a mobile target which emits a radio signal in response to the occurrence of a tracking effort initiation event. The tracking stations have a GPS receiver or like means for determining their position, a radio direction finder responsive to the radio signal that determines the vector to the mobile target, a two-way communications system and a computer. The mobile transmit and receive stations exchange their position and direction to target information via the two-way communications systems, enabling the stations to triangulate the location of the target with their computers.
