Calculation accuracy of the spatial parameter signal with improved robust in the local navigation satellite system or global navigation satellite system .

摘要

PROBLEM TO BE SOLVED: To provide operation of an accuracy parameter of spatial signals in robust detection to be satisfactorily and simultaneously executed by classical approach.;SOLUTION: A method for operating the accuracy parameter of spatial signals includes at least one of a step (S10) for measuring an error vector of an individual spatial signal, a step (S12) for mapping the error vector of the individual spatial signal in a service area, a step (S14) for stacking empirical sample sets, a step (S16) for processing an estimated density function of the stacked sample sets, a step (S18) for individually over-bounding density functions in Galileo over-bound detection or in a pair over-bound detection having excess mass, and a step (S20) for selecting the worst case caused by a predetermined requirement.;COPYRIGHT: (C)2012,JPO&INPIT
