Global Positioning System (GPS) was developed by the US Department of Defense to provide all-weather round-the-clock navigation capabilities for military ground, sea, and air forces. Since its implementation, GPS has also become an integral asset in numerous civilian applications and industries around the globe, including recreational used (e.g., boating, aircraft, hiking), corporate vehicle fleet tracking, and surveying. GPS employs 24 spacecraft in 20,200 km circular orbits inclined at 55 degrees. These vehicles are placed in 6 orbit planes with four operational satellites in each plane.
The first eleven spacecraft (GPS Block 1) were used to demonstrate the feasibility of the GPS system. Keyword(s) : #Planet, #Satellite, #Telecommunications, This is OUTSIDE of a Space Revue. Last modified: 05/07/2015 @ 14h00
