Embodiments of the present invention provide a method, device, and electronic terminal for monitoring orbital parameters. The method includes: receiving and decoding a binary data stream of a subframe structure in a global navigation satellite system navigation message, and the binary data stream includes multiple Orbital parameters; calculate the current parameter error value of the orbital parameter; determine the threshold range of the error according to the error distribution model; judge whether the current parameter error value is within the threshold range, if so, determine that the orbital parameter is normal and output normal monitoring result. In this way, the accuracy of the orbital parameters in the navigation message of the global navigation satellite system can be monitored in real time, and the abnormality of the orbital parameter accuracy can be identified, which provides a way to find abnormal problems and avoid situations where the cause of the abnormality cannot be determined .
Description
technical field [0001] The invention relates to the field of monitoring and evaluation, in particular to a method, device and electronic terminal for monitoring orbital parameters. Background technique [0002] In the navigation and positioning service, when the satellite signal is wrong, it will cause user confusion and inconvenience, and there will be a great potential safety hazard. GNSS (Global Navigation Satellite System, Global Navigation Satellite System) monitoring refers to the monitoring of any abnormality in GNSS that may affect the performance of navigation and positioning services, which is of great importance and application value. At present, the monitoring of GNSS at home and abroad focuses on the evaluation of the use results, rather than substantive monitoring. When satellite data is abnormal, the cause cannot be known, and good services cannot be provided to users. Contents of the invention [0003] In view of this, the purpose of the embodiments of the...
