Abstract

The invention discloses a differential positioning system for satellite navigation, which comprises base station equipment, a cloud server and mobile station equipment. the base station equipment is used for calculating differential enhancement information in real time, receiving a differential enhancement service application of the mobile station equipment and verifying the legality of the service application; The mobile station equipment applies for service from the base station equipment, verifies the validity of service response, and performs differential positioning settlement by using the differential enhancement information; And the cloud server is responsible for data transmission between the base station equipment and the mobile station equipment. The base station equipment and the mobile station equipment in the device are both equipped with the GPRS data communication modules, and the GPRS data communication modules and the mobile station equipment carry out information interaction through the cloud server by utilizing the mobile communication network, so that system data communication is not influenced by sight distance transmission any more, the requirement of system work on the environment is greatly reduced, and the safety of the whole system is improved.

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...
