Multi-mode position location method
First Claim
1. A multi-mode position location method for a detection device comprising the steps of:
- first determining by a processor whether a Global Positioning System (GPS) position of the detection device is valid;
first providing by the processor a differential corrected GPS position of the detection device to a master control station;
second determining by the processor whether a multilateration system position of the detection device is valid, if the GPS position is not valid; and
second providing by the processor a multilateration system position of the detection device to the master control station, if the multilateration system position is valid.

Abstract
A multi-mode position location method detects the location of movable detection devices which are attached to movable carriers in a simulated battlefield. The multi-mode position location method employs three modes of position location of the detection devices. The first mode is a Global Positioning System (GPS) differentially corrected position of the detection device. The second mode is a multilateration determined position of the detection device. The third mode is an autonomously determined GPS position of the detection device. The autonomously determined position is determined without any differential GPS corrections. The most accurately determined position of the detection device may be used for area weapons effects simulation and carrier tracking by transmitting the carrier'"'"'s position to a master control station.
