Abstract

The invention discloses a CORS-based sub-meter integrated positioning navigation system and a corresponding navigation method. By acquiring the correction number of a CORS base station server and based on an RTD algorithm, the positioning accuracy of satellites is improved, and a high-accuracy sub-meter positioning result can be output. Moreover, as an INS technology is not dependent on the signal strength and is undisturbed, continuous high-accuracy and high-stability position information can be provided for users.

Description

technical field

[0001] The invention relates to the application field of satellite positioning and navigation. Background technique

[0002] With the continuous development and improvement of satellite navigation and positioning systems such as GPS and Beidou, the application of satellite navigation and positioning has also emerged at the historic moment and has continued to grow and develop. , emergency vehicle position reports, etc., the requirements for position accuracy are getting higher and higher, and it is necessary to be able to realize lane-level positioning and navigation, which means that the positioning and navigation system must be able to provide sub-meter level positioning accuracy. Generally, the accuracy of traditional satellite positioning is 5-20m, which is low in accuracy and cannot meet the monitoring needs of actual road vehicles, and because satellite signals are easily interfered, the real-time positioning stability is poor. etc. GPS and Beidou sate...
