Satellite communication positioning method, satellite communication system and electronic equipment

The invention provides a satellite communication positioning method, a satellite communication system and electronic equipment. The method comprises the steps that a short message management platform determines an ionosphere correction parameter and observation value noise according to an ionosphere resolving parameter and observation data, and the observation value noise comprises the weight of an elevation angle and the weight of a signal-to-noise ratio. And the short message management platform transmits the ionosphere correction parameter and the observation value noise to each satellite, and each satellite performs differential coding processing according to the ionosphere correction parameter to obtain compressed data. And each satellite encrypts the compressed data and the observation value noise to obtain a short message, and sends the short message to the terminal device, so that the terminal device obtains a positioning result based on the compressed data and the observation value noise sent by each
