Introduction and application of Beidou timing system

Introduction and application of Beidou timing system

Beidou timing System is the Chinese people's own satellite timing system, is the pride of our countrymen. Today XI ' an synchronous Electronic Technology Co., Ltd. take you to understand the Beidou timing system and application.

1 introduction of Beidou satellite navigation system

Beidou time-based timing equipment was first entered into the field of communication in 2003, before 2008 mainly provides frequency synchronization services, after which can provide simultaneous synchronization and frequency synchronization Services. According to the test situation of the past ten years, we can see that the Beidou equipment can meet the requirements of frequency synchronization and time synchronization in the communication network under normal circumstances, especially the Beidou equipment produced after 2008 has reached the level of GPS satellite receiver equipment generally. It can meet the requirement of frequency synchronization and time synchronization for various communication equipments in communication network completely.

2 and the application of Beidou timing

Beidou timing is the fundamental guarantee of Communication network security Group Network in terms of synchronous network, China's Frequency synchronization network adopts multi-benchmark hybrid synchronization mode, that is, the entire network deployment of multiple 1-level reference clock equipment, and the need to configure high-performance satellite timing receiver, to ensure the timing performance of the network. In China, the time synchronization network adopts the distributed network method, that is, the high-performance satellite timing receiver should be configured on every time synchronization device to ensure the time accuracy of the whole network.

As far as the mobile communication network is concerned, the CDMA base station, CDMA2000 base Station and TD-SCDMA base station all need high-precision time synchronization, and the GPS timing module is now configured on each base station. If the time synchronization between the base station and the base station does not meet certain requirements, it may lead to the mismatch of instructions in the selector, which will cause the call connection not to be established and affect the quality of the wireless service.

Beidou Time service performance can meet the needs of the communication network, based on the Beidou/GPS dual-mode timing equipment in the first 2003 into the field of communication, before 2008 mainly provide frequency synchronization services, since then can provide simultaneous synchronization and frequency synchronization Services. According to the test situation of the past ten years, we can see that the Beidou equipment can meet the requirements of frequency synchronization and time synchronization in the communication network under normal circumstances, especially the Beidou equipment produced after 2008 has reached the level of GPS satellite receiver equipment generally. It can meet the requirement of frequency synchronization and time synchronization for various communication equipments in communication network completely.

Summary

At present, the Beidou Time service has been widely used in public security, security industry, fishery supervision, traffic management and many other special industries, in the military field, the Beidou service is of great significance, has a real own timing source, out of the dependence on foreign satellite systems, of course, in the ordinary civil timing and communication services have also begun.
