Abstract

Abstract: Integrity is an important indicator of the reliability of satellite navigation systems. Improving the integrity service is an important part of BDS global navigation system construction.This paper presents a SISA (signal in space accuracy) calculation algorithm with variance conversion prediction based on apriori precision adjustment, and the performance of the SISA for error envelopment is evaluated based on the real data of new generation BeiDou navigation system.SISA_oe is verified by the precision orbit overlap error in orbital plane, and the SISA_oc is verified by the orbital radial overlap error, SLR check error and clock error estimated by the two-way time-frequency transmission.The results show that the error envelope performance of the SISA_oe parameter for orbital plane error is 99.6%;the error envelope performance of the SISA_oc parameter for the track radial and clock error is 98.5%, and for the SLR check error is 99.5%.

Key words: BeiDou navigation system(BDS), signal in space accuracy(SISA), integrity, satellite laser ranging(SLR)
