GPS-L1/BDS-B1 Non-Overlapping Frequency Tight Combination Relative Positioning
Abstract We research the short baseline GPS-L1/BDS-B1 tight combination non-overlapping frequencies relative positioning algorithm. We deduce, under the short baseline GPS L1/BDS-B1 non-overlapping frequencies close combination, the mathematical model of relative positioning. The GPS-L1/BDS-B1 DISB non-overlapping frequency stability and DISB calibration method is introduced in detail. The test results show that, compared with the traditional GPS/BDS loose combination relative positioning model, the compact combination relative positioning model with pre-calibrated DISB can effectively improve the success rate of fuzzy degree fixation; the fewer satellites available, the more obvious the improvement effect is.
