Research on Ionosphere Calibration Methods in GNSS Atmospheric Radio Occultation
摘要
Abstract
In this paper, the calibration principles of ionosphere calibration methods are described in detailed, and the effects of these methods are analyzed by using simulating method. The results are as follows： the calibration error of single frequency ionosphere cali- bration method is large because the precision of pseudo range is bad. This method is worked when the receiver has only one frequency or there was not L2 data. In the methods of double frequency calibration methods, A combination of L1 and L2 phase method is worst because it is not considerable of the difference of two radio waves~ propagating paths. A linear combi- nation of L1 and L2 bending angle is the best method of all the ionosphere calibration meth- ods.关键词
