Abstract
It is very important to get precise positioning information continuously in the UAV RTK. However, the complex environment often degrades the observation quality or even introduces several gross errors which will seriously affect the accuracy and reliability of the results. In this paper, a new method of multi gross error detection with the constraint of epoch variation is put forward and validated by the UAV-PPK. The result shows that it can effectively detect multiple gross errors and handle the gross-errors and cycle-slips in a different way. Besides, it can also guarantee the stability of the filtering and significantly increase the ambiguity fixing rate and positioning accuracy. Thus, the reliable and precise positioning information can be continuously supplied for UAV RTK.
