Performance Analysis of B2b+E5b Combined Precise Single Point Positioning
Based on the PPP-B2b service provided by BDS-3,the static and pseudo dynamic precise single point positioning accura-cy,convergence time,pseudo range observation accuracy,and evaluated ZTD accuracy of B2b,E5b,B2b+E5b are compared and an-alyzed.The research results show that the B2b static and dynamic precise single point positioning accuracy is at the centimeter level,the static convergence time is within 100 min,and the dynamic convergence time is within 110 min,which is better than the E5b pre-cise single point positioning performance.Compared with B2b and E5b,B2b+E5b precise single point positioning performance,pseu-do range observation accuracy and evaluated ZTD accuracy have significantly improved,among which the improvement effect is the most obvious compared with E5b,which can provide some reference for future research on BDS-3 B2b precise single point positio-ning.
