发明名称 Integrity monitoring in a position location system utilizing knowledge of local topography
摘要 A system for and method of deriving a position estimate of a receiver from a plurality of parameter measurements is provided. Each measurement is derived from a correlation function, which in turn is derived by correlating a signal received at the receiver with an identification code uniquely identifying a transmitter visible to the receiver. A plurality of position estimates are derived, each from a different subset of the plurality of measurements. Based on local topography, one of the position estimates is selected as the best estimate of the position of the receiver.
