A cors data coding transmission system suitable for long-distance communication

Abstract

The invention discloses a CORS data coding transmission system applicable to long-distance communication. The system comprises a mobile big dipper CORS vehicle used for receiving data through a big dipper receiver on the vehicle and sending the data to a CORS service system; a CORS service system used for grouping difference data information in CORS data; a coding module used for performing anti-interference coding on high broadcasting frequency information and low broadcasting frequency information; a high-power ultra-shortwave radio station used for receiving the data coded by the CORS service system through an ultra-shortwave interface, sending the coded data to a long distance receiving end radio station, and accomplishing data transmission; and a decoding module used for decoding the code received by the receiving end radio station, sending the decoded CORS data to a background server, and accomplishing transmission of the CORS data. According to the system, by employing the big dipper CORS vehicle and the high-power ultra-shortwave radio station, long-distance credible transmission of the CORS data is realized through extraction and coding of the CORS difference data, the error rate of long-distance communication of the CORS data is reduced, and the communication quality is improved.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a CORS data coding transmission system suitable for long-distance communication. Background technique [0002] The Beidou satellite navigation system can provide high-precision, high-reliability positioning, navigation and timing services, and has the service characteristics of combining navigation and communication. Through 19 years of development, this system has been applied in many fields such as surveying and mapping, fishery, transportation, telecommunications, water conservancy, forest fire prevention, disaster reduction and relief, and national security, and has produced significant economic and social benefits, especially in Wenchuan, Sichuan , Qinghai Yushu earthquake relief has played a very important role. [0003] In some disasters or emergency situations, when the infrastructure and communication facilities are damaged, the Beidou CORS vehicle can take advant...

AI Technical Summary

Problems solved by technology

However, in disaster or emergency environments, based on the limited communication capabilities and one-way transmission limitations of mobile CORS, transmission errors will seriously affect the function of CORS high-precision positioning services, and even lead to service failure in severe cases.

In this way, the maximum effect of the Beidou CORS vehicle cannot be exerted
