The invention discloses a high-precision positioning navigation system based on Beidou navigation. The system comprises a positioning navigation terminal device and a ground-based augmentation system.The positioning navigation terminal device is connected to the ground-based augmentation system through a network and is provided with a processor, an LCD, a camera, a USB interface, a dead reckoningsensor, a Beidou receiver, and a wireless communication module. The processor is provided therein with a BDC / DR positioning algorithm, and is connected to the network through the Beidou receiver. A primary service platform, a backup service platform, a data communication network, and a reference station are disposed on the ground-based augmentation system. The ground-based augmentation system isconnected to the network through the primary service platform and the backup service platform. The primary service platform and the backup service platform are both connected to the reference stationthrough the data communication network. The high-precision positioning navigation system improves the accuracy of positioning data by the ground-based augmentation system, and improves the accuracy ofthe positioning navigation by using the BDC / DR positioning algorithm.
Description
technical field [0001] The invention relates to the field of Beidou navigation, in particular to a high-precision positioning and navigation system based on Beidou navigation. Background technique [0002] China's Beidou Satellite Navigation System (BDS) is a global satellite navigation system developed by China itself. It is the third mature satellite navigation system after the US Global Positioning System (GPS) and the Russian GLONASS Satellite Navigation System (GLONASS). Beidou Satellite Navigation System (BDS), GPS of the United States, GLONASS of Russia, and GALILEO of the European Union are certified suppliers by the United Nations Satellite Navigation Commission. However, in the prior art, most of the high-precision positioning and navigation systems used for Beidou navigation have the following deficiencies: [0003] For example, the application number is 201410681371.0, and the patent name is an invention patent for a high-precision positioning and navigation sy...
