Comparison of Satellite-Induced Code Bias between BDS-2 and BDS-3 Satellites
摘要
Abstract
By analyzing the multipath (MP) combination of BDS-2 satellite,the code bias of BDS-2 satellites is confirmed as elevation,satellite,and frequency dependent.For BDS-3 satellites,the MP combination is calculated and the elevation-dependent model is developed for each satellite on different frequencies by the polynomial fitting method.The observation data of BDS-2 satellites are from IGS station JFNG,while the data of BDS-3 satellites are from self-test data SGG0.The results of BDS-3 satellites show that the code bias is ignorable.关键词
