Abstract:Using GF combination of adaptive threshold model in static and dynamic environments, we develop the method of BDS peri-hop detection for different orbiting satellites. The results show that the method can be applied to circumferential hop detection under unfavorable observation environments, such as low altitude angle and active ionospheric period of the satellites in each orbit of BeiDou, avoiding misjudgment and omission in each sampling rate as much as possible, significantly improving detection accuracy when the sampling rate is low and the multi-path error is large.
