New optimal approach to Global Positioning System/Differential Global Positioning System integrity monitoring

Journal of Guidance, Control, and Dynamics, 1996
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 ...
