What are the functions and significance of Beidou satellite navigation system?

The function and significance of the Big Dipper satellite navigation system:

1. Significance

1. National security

We should set up our own satellite navigation system to avoid being controlled by people in future wars, and at the same time we have the same means to counter the enemy.

2, economic benefits

The Big Dipper satellite navigation system can create huge economic benefits every year. On the one hand, we save the huge amount of money originally used to introduce foreign systems.

On the other hand, our own system serves domestic users at a low price, which allows more industries to apply this high-tech equipment, thus creating more social value and material wealth. On the other hand, we can put our system into the international market, participate in international competition and earn foreign exchange.

3, technical reserves

The development of science and technology will never stop. We have developed our own satellite navigation system, and we have corresponding technical reserves, which means that our country's scientific and technological level has reached the advanced level in the world. With these technical reserves, we can seize the commanding heights in the new round of scientific and technological tide in the future.

II. Function

The construction goal of Beidou satellite navigation system is to build an independent, open, compatible, advanced, stable and reliable navigation system covering the whole world, providing short message communication, precise timing and precise positioning services. Beidou satellite navigation system promotes the formation of satellite navigation industry chain, forms a perfect national satellite navigation application industry support, promotion and guarantee system, and promotes the wide application of satellite navigation in various industries of national economy and society.

Main functions and uses of Beidou navigation system

1. Four major functions:

1. Short message communication: Beidou system user terminal has bidirectional message communication function, and users can transmit short message information of 4-6 Chinese characters at a time.

2. precise timing: Beidou system has precise timing function, which can provide users with time synchronization accuracy of 2ns-1ns.

3. Positioning accuracy: the horizontal accuracy is 1m (1σ), and it is 2m after the calibration station is set up (similar to differential state).

4. The maximum number of users accommodated by the system: 54, users/hour.

second, the use of Beidou navigation system:

1. Personal location service

When you enter an unfamiliar place, you can use your mobile phone with Beidou satellite navigation receiving chip or vehicle-mounted satellite navigation device to find your route.

2. Meteorological application

The meteorological application of Beidou navigation satellite can promote the weather analysis and numerical weather forecast, climate change monitoring and prediction in China, and also improve the service level of space weather early warning, and enhance the meteorological disaster prevention and mitigation ability in China.

3. Road traffic management

Satellite navigation will help to slow down traffic jams and improve the level of road traffic management. By installing a satellite navigation receiver and a data transmitter on the vehicle, the position information of the vehicle can be automatically forwarded to the central station within a few seconds.

4. Railway Intelligent Transportation

Satellite navigation will promote the upgrading and transformation of traditional transportation modes.

5. Shipping and water transportation

Beidou satellite navigation system will provide navigation and positioning and safety guarantee for ships sailing on the water under any weather conditions. At the same time, the unique short message communication function of Beidou satellite navigation system will support the development of various new services.

6. Air transportation

By effectively combining Beidou satellite navigation system with other systems, it will provide more security for air transportation.

7. Emergency rescue

In addition to navigation and positioning, Beidou satellite navigation system also has the function of short message communication. Through satellite navigation terminal equipment, the location and disaster situation can be reported in time, effectively shortening the rescue search time, improving the timeliness of emergency rescue and disaster relief, and greatly reducing the loss of people's lives and property.

8. Guiding Grazing

In October p>214, Beidou system began to pilot the construction of Beidou satellite grazing information guidance system in pastoral areas of Qinghai Province, mainly relying on the management platform of grazing intelligent guidance system in pastoral areas, Beidou intelligent terminal dedicated to herders and automatic data collection station in pasture to realize data information transmission, and through the transit and relay processing of Beidou ground station and the Big Dipper group, the dynamic monitoring of pasture grass, cattle and sheep was realized
