The invention discloses a Beidou navigation positioning system and a Beidou navigation positioning optimization method. The Beidou navigation positioning system includes a Beidou / GPS double-positioning antenna, a sensor group, a clock check module, a printer, a camera, an SIM card reading device, a communication module and a central controller. According to the optimization method, different positioning modes are switched intelligently according to currently acquired Beidou satellite signal intensity. With the Beidou navigation positioning system and a Beidou navigation positioning optimization method of the invention adopted, when signal dead zones or signal dropout which is caused when a single mode is adopted in a traditional system or method appears, the signal intensity of the Beidou satellite can be detected and optimized, and intelligent switching can be carried out according to signal strength, and the problem of positioning dropout and incapability of realizing positioning when a terminal enters a positioning signal intensity dead zone can be solved.
Description
technical field [0001] The invention relates to the technical field of Beidou positioning, in particular to a Beidou navigation and positioning system and an optimization method. Background technique [0002] Beidou Satellite Navigation System (referred to as Beidou System, English name is BeiDou Navigation Satellite System, abbreviated as BDS), generally refers to China's second-generation satellite navigation system, English referred to as BDS, used to be called COMPASS, also known as Beidou No. 2, It is an independently developed and independently operated global satellite navigation system that is compatible with other satellite navigation systems in the world. It is also one of the most critical national infrastructures in our country. [0003] At present, the Beidou system has been applied in more and more fields, and has formed a certain market scale in various aspects such as positioning, navigation, timing, and communication. From the perspective of products, high-...
