The global positioning system (GPS) was developed by the US Department of Defense in the early 1970s to serve military navigational requirements. The first satellite was launched in 1978 and the system was declared operational in 1995. It is based on a network of at least 24 satellites (with room for six further satellites) orbiting the Earth in nearly

Summary: The problems of global positioning system (GPS) and differential GPS (DGPS) integrity monitoring are addressed. Receiver-autonomous and station-based integrity monitoring algorithms are discussed. Integrity monitoring consists of two functions: detection of the fact that a satellite channel produced wrong data and isolation or identification ...
