Problems solved by technology
Cycle slips generally occur when satellite observation conditions are poor, such as signal interference, multipath effects when the satellite altitude angle is low, etc. At this time, the errors of pseudorange and Doppler observations will increase several times or even dozens of times. times; thus the success rate of cycle slip detection and repair will be greatly reduced
The pseudo-range phase combination method and TurboEdit method require dual-frequency or even triple-frequency observations, which are not available for all satellites at any time, so the pseudo-range phase combination method and TurboEdit method cannot be applied to all scenarios

The invention discloses a cycle slip processing method and device, a computer storage medium and a terminal, and the method comprises the steps: determining whether a global satellite navigation system (GNSS) generates cycle slip or not according to the double-difference ambiguity of a first satellite and each second satellite; when it is determined that a cycle slip occurs in the GNSS, determining a satellite in which the cycle slip occurs according to the double-difference ambiguity of the first satellite and each second satellite; determining the jump whole cycle number of the cycle slip through a preset algorithm; performing cycle slip repair on the satellite with cycle slip according to the determined whole cycle number of jump; wherein the first satellite is the satellite with the most observed value frequency points in the GNSS; the second satellites comprise remaining satellites in the GNSS except the first satellite. The embodiment of the invention can be suitable for any satellite observation condition scene, cycle slip detection is realized through the double-difference ambiguity under the condition that a double-frequency or three-frequency observation value is not needed, the satellite with cycle slip is determined through the double-difference ambiguity, and the success rate of cycle slip detection and repair is improved.
Description
technical field [0001] This article relates to, but is not limited to, satellite communication technology, especially a method, device, computer storage medium and terminal for implementing cycle slip processing. Background technique [0002] At present, there are a number of satellite navigation systems that can provide users with positioning services, namely, Satellite Navigation and Positioning System (GNSS), Global Positioning System (GPS) in the United States, GLONASS in Russia, Beidou in China, and the European Union. Galileo and Japan's Quasi-Zenith Satellite System (QZSS). The joint positioning of multiple satellite navigation systems greatly improves the availability, reliability and accuracy of satellite navigation and positioning. Therefore, satellite navigation and positioning has been widely used in many fields, including vehicle navigation, surveying and mapping, precision agriculture, intelligent robots, unmanned aerial vehicles and unmanned driving.
