What is CORS?

CORS, whose full name is Continuous Operation Reference Station and Chinese name is Continuous Operation Reference Station, is the product of multi-faceted and deep crystallization of high and new technologies such as satellite positioning technology, computer network technology and digital communication technology. ?

CORS system consists of five parts: reference station network, data processing center, data transmission system, positioning and navigation data broadcasting system and user application system. Each reference station and monitoring and analysis center are connected into a whole through a data transmission system to form a private network.

Practical application of CORS in China;

The first CORS system in China has been built in Shenzhen and has been applied in comprehensive survey. Similar CORS systems have been or are being established in some provinces and cities in China, such as Guangdong, Jiangsu, Beijing, Tianjin, Shanghai, Guangzhou, Dongguan, Chengdu, Wuhan, Kunming, Chongqing and Qingdao.

The establishment of Sichuan Seismological Bureau of CDCORS has been running for more than three years, and its main purpose is to monitor the earthquake-stricken areas in Sichuan. However, the potential function mining has achieved certain benefits in the development and utilization of GPS geodesy, the authorization of open network access through dial-up login, and the realization of real-time high-precision differential positioning for users. Sichuan province started the construction of Beidou satellite navigation network in the whole province.

In addition to the basic framework and application of the government, the application of CORS system in the commercial field has also entered the practical operation stage. Xingwei Information Technology's high-precision positioning system for port transport vehicles based on CORS technology effectively solves the problems of low positioning accuracy and poor scheduling caused by high logistics density and strong mobility of port vehicles.
