METHOD FOR RESETTING ERROR IN LOCATION MEASUREMENT AFTER CYCLE SLIP IN GPS SATELLITE RADIO WAVE

摘要

PROBLEM TO BE SOLVED: To provide a method for resetting errors in location measurements after the occurrence of cycle slips due to radio disturbance of GPS satellites.;SOLUTION: In the method for resetting errors in location measurements, (a) the location (Xe, Ye, Ze) of a mobile station is estimated after the occurrence of cycle slips, (b) the location (Xc, Yc, Zc) of the mobile station is obtained by hypothetical ambiguities, (c) the hypothetical ambiguities are taken as estimated ambiguities when the obtained location (Xc, Yc, Zc) lies within a previously set range to the location (Xe, Ye, Ze) of the mobile station, and (d) the estimated ambiguities are verified by the processing (c) at a following time to obtain definite ambiguities.;COPYRIGHT: (C)2003,JPO
