The invention discloses a differential positioning system for satellite navigation, which includes a reference station device, a cloud server and a mobile station device. The reference station device is used to calculate differential enhancement information in real time and receive a differential enhancement service application from the mobile station device, and Verify the legitimacy of the service application; the mobile station device applies for service to the base station device, verifies the legitimacy of the service response, and uses the differential enhancement information to perform differential positioning settlement; the cloud server is responsible for the data between the base station device and the mobile station device transmission. Both the base station equipment and the mobile station equipment in this device are equipped with GPRS data communication modules, and the two use the mobile communication network to exchange information through the cloud server, so that the system data communication is no longer affected by line-of-sight transmission, which greatly reduces the system work. environmental requirements, and improve the security of the entire system.
Description
technical field [0001] The invention belongs to the field of satellite navigation, in particular to a differential positioning system for satellite navigation and its realization method. Background technique [0002] An artificial satellite is an unmanned spacecraft that operates periodically in a closed orbit according to a preset trajectory. It provides powerful data monitoring for human scientific exploration, communication calls, weather forecasting and resource detection. The differential positioning system is to improve the measurement and positioning accuracy of other equipment (mobile station equipment) within a certain range by using the measurement positioning error measured on the known coordinate point (reference station equipment). The reference station equipment is used to measure the error with spatial correlation or its influence on the measurement and positioning results, and the mobile station equipment corrects its observation value or positioning results...
