论文摘要
The detection and repair of cycle slip are very important for high-precision positioning.Detection cycle slip for triple-frequency detect method should be as small as possible and elevation of satellite become a factor that cannot be ignored.First,three optimal linear independent combinations for GPS are selected to detect cycle slip.Then the equation of success rate of cycle slip detection and elevation is derived,40 degree is set as threshold for cycle slip detection.When elevation is higher 40 degree,overall detection success rate is above 96.91%.Finally,data of GPS is tested to observe the actual detection of the cycle slip.The result shows that WL and NL combinations are affected by elevation and have obvious changes.Due to code observation in EWL combination,elevation has a smaller impact on EWL combination.
