Highly Integrated GPS Receiver Overcomes Jamming. Pinpoints Location

摘要

Handheld global positioning satellite (GPS) receivers are used by soldiers to find their way in strange lands, especially at night. GPS receivers are also used to find downed pilots and locate other strategic personnel. After the Gulf War, the U.S. Army announced it would install GPS in all armored vehicles to help minimize friendly fire incidents, which was a major source of casualties in Operation Desert Storm. Friendly fire incidents most often were caused by armored unit commanders who were lost in the featureless Iraqi desert or were out of position during ground attacks. It is clear from these experiences that the military would like to have GPS location capability on every person, vehicle and projectile. The projectiles do not stop at cruise missiles, but also include 155-mm Howitzers and 5-inch Navy deck guns with GPS guidance. These military GPS receivers must be able to receive the military version of the spread-spectrum code, and they must be antijamming receivers.
