|Rockwell Manpack Global Positioning System (GPS) Receiver
Model number: AN/PSN-8
Date manufactured: 1980
Item History: The Manpack was the first man-portable Global Positioning System (GPS) receiver. It was developed by Rockwell Collins (then the Collins Government Avionics Division of Rockwell International) as part of the GPS phase 2 preproduction contract and deployed during the GPS phase 3 initial production equipment contract. It is a one-channel set that weighs about 17 lbs. and was designed to be carried on a rucksack frame, backpack style. However, due to its weight, it was most often strapped to a truck or helicopter. Since it was a single channel GPS receiver, it was not able to track multiple GPS satellites simultaneously. To form the GPS position solution, the Manpack sequentially acquired and tracked four GPS satellites. A cryptographic code could be loaded into the set, thereby giving it the capability to provide Precise Positioning Service (PPS). Adaptations of the Manpack were used in early GPS missile integrations including Conventional Air Launched Cruise Missile (CALCM) and Standoff Land Attack Missile (SLAM).
