Satellite navigation positioning signal-to-noise ratio weighting method, system and equipment and storage medium

The embodiment of the invention provides a satellite navigation and positioning signal-to-noise ratio weighting method, system and device and a storage medium, and belongs to the technical field of satellite navigation and positioning. According to the scheme, the satellite signal-to-noise ratio reconstruction model is constructed in the open environment, the satellite elevation angle is input into the corresponding satellite signal-to-noise ratio reconstruction model, the reconstruction signal-to-noise ratio interval of the satellite observation data in the open environment is obtained, and the satellite weight is determined according to the observation signal-to-noise ratio and the reconstruction signal-to-noise ratio interval. The signal-to-noise ratio analysis under the satellite observation value can be carried out based on the signal-to-noise ratio in the face of a shielding environment, so that the importance of satellite observation data with few diffraction errors is highlighted, the quality of the s
