Brother Zhacai of Taiwan Province Province said Beidou satellite is better than GPS. What are the black technologies of Beidou navigation?

In China, China's homemade Beidou satellite navigation system is inevitably not compared with American GPS. Yesterday, Taiwan Province Province's "famous mouth" Huang Shicong (who claimed to be the mustard tuber brother a few days ago because of the mustard tuber incident) began to tout the Beidou satellite system in Chinese mainland: wide and accurate, surpassing GPS to become the overlord. Beidou satellite itself is a black technology.

Here, Bian Xiao briefly introduces the Beidou satellite system.

At the end of 20 12, Beidou system officially provided regional services, and Beidou application and industrialization promotion officially entered the fast lane. At the beginning of the application and promotion of Beidou, the research institute actively laid out various Beidou industry applications, such as transportation, fishery, forestry, agriculture, electric power and other industries. Our products have played an important role in promoting the large-scale application of China Beidou.

Here are some aspects that are closely related to us. First of all, Beidou system can be used to realize accurate positioning and real-time monitoring of vehicles, and provide many personalized services such as historical track playback and overspeed alarm to ensure driving safety. The "tracking-vehicle monitoring system" developed by the institute provides scientific and technological means from the aerospace field for vehicle safety supervision.

In addition, smart tourism system, Beidou agricultural machinery automatic driving system, indoor positioning system, deformation monitoring system, wind farm anemometer application, smart pasture, mine monitoring and so on. All the completed Beidou systems have Beidou wisdom contributed by the Institute. In areas with poor ground signals, emergency rescue can be achieved through Beidou SMS; Through Beidou high-precision monitoring, geological disaster monitoring in mining area is realized; Through the integration of Beidou high-precision positioning technology, inertial integrated navigation technology and intelligent control technology of agricultural machinery, agricultural automatic driving is realized and work efficiency is improved. The Beidou application products of the Institute are varied. Through years of application and promotion, Beidou has been widely used in transportation, forestry, fishery, civil affairs and other fields.

At present, the Beidou system is under active construction, and it is planned to build a global system around 2020. While steadily promoting the construction of Beidou system, China Academy of Space Technology will, as always, actively participate in the application and industrialization development of Beidou system.
