An Abnormal Data Eliminating Method Used in Low-dynamic Carrier Phase DGPS Position System
Jiancheng Fang · Journal of Chinese Inertial Technology · 2003
On the base of analysising several general abnormal data eliminating rules, a new abnormal data eliminating method used by the carrier phase DGPS position system in low dynamic environment is proposed in this paper, which is robust and adaptable. In this method descending length is used to devide data into groups, then median based polynomial regression is applied to each group and the abnormal data is circularly eliminated by fast algorithm. It provides reliable carrier phase DGPS position data for improving the precision of the integrated GPS/INS navigation system.
