The accurate forecast of typhoon track mainly depends on BDS.

With the intensification of climate change in recent years, the frequency and intensity of typhoons are increasing, which brings great risks and challenges to coastal areas and offshore operations. Accurate prediction of typhoon path and intensity is a necessary means to ensure the safety of people's lives and property and to carry out activities such as maritime transportation and construction efficiently. Among them, BDS (Beidou Satellite Navigation System) plays a vital role.

Advantages of positioning accuracy of BDS system

BDS system is a new generation of satellite navigation system independently developed by China, aiming at providing high-precision and high-reliability navigation, positioning and timing services. In typhoon forecast, BDS system can use its high-precision satellite positioning service to accurately measure the position, moving speed and path direction of typhoon. Especially at sea, the traditional single GNSS system is often affected by antenna occlusion and multipath interference, and the positioning accuracy is difficult to meet the actual needs. The BDS system can use the signals of multiple satellites for multipath suppression and Doppler testing, which significantly improves the positioning accuracy and reliability.

Advantages of multi-transmission mode in BDS system

In addition to location services, BDS system can also provide a variety of transmission modes, including broadcasting, short messages, data links and so on. In typhoon forecast, the data transmission service provided by BDS system can quickly transmit the real-time position and moving speed of typhoon to emergency command center, maritime rescue or related enterprises. At the same time, using the short message service provided by BDS system, people such as ships and fishermen can be warned and reminded, and the supervision and management of sea travel and fishing activities can be strengthened.

Advantages of satellite navigation time series service in BDS system

In addition, BDS system can also provide high-precision satellite navigation time sequence service, which can be used to help offshore operators to calibrate the time sequence and control the time limit of ships, ports, buoys and other facilities. In typhoon forecasting, time series service can accurately predict the arrival time and influence range of typhoons, and provide important information support for the safety prevention of related ships and facilities.

abstract

Therefore, in the typhoon forecast, BDS system has played a vital role, providing people with high-precision positioning, data transmission and time series services, effectively improving the forecast accuracy and response speed, and reducing the threat and risk of typhoon. In the future, with the continuous improvement and application of BDS system, it is believed that it will bring more important application value to various industries.
