Application Analysis of RTS Smoothing on the Data Post-processing of BDS/INS Integrated Navigation

In the data post-processing of BDS/INS integrated navigation, the high precision smoothing algorithm is researched aimed at solving the problem of precision degradation caused by the loss of lock of the BDS receiver for a long time. The RTS smoothing algorithm is analyzed when the BDS signal is interrupted, and the equations are given at the same time experimental program are designed. The results show that RTS is not only able to have a smoothing effect on the navigation solution results, but also can significantly weaken the influence of BDS loss of lock to the integrated navigation system.
