| Abstract: | With the application of multi-frequency observation data of the new generation of satellite navigation and positioning system,using the combination of multi-frequency carrier phase data will make cycle slip detection and restoration more quickly and accurately.This paper used the combination of multi-frequency observation theory,selected combination factors for BeiDou data,combined with pseudorange/carrier phase method and researched on the cycle slip detection and restoration of BeiDou tri-frequency carrier phase data.The result showed that not only small cycle slip but also large cycle slip and gross error could be accurately and quickly detected by this method. |
