China's Goffin-3 03 satellite was successfully launched. What is the specific significance of the launch of this satellite?

Gao Fen-3 03 is the third satellite in the series of Gao Fen-3, which was successfully launched at Jiuquan Satellite Launch Center. This satellite is mainly used for continuous observation of the global ocean and environment, and the observation period will be shortened to 12 hours, thus obtaining updated remote sensing data and providing a good foundation for application. With the three satellites in orbit, the Samsung network has been completely built, which can cover most of the world's sea areas and obtain real-time ocean observation data.

Gaofen-3 satellite 0 1 was launched in 20 16. It is a very important satellite in China's high-resolution Earth observation system. It is equipped with advanced synthetic aperture radar and has a very long service life. The resolution of Gao Fen -3 0 1 satellite is one meter, and the principle of microwave imaging is adopted. Microwave can directly acquire and transmit data through the clouds on the earth's surface, and will not be affected by the weather. But also can realize multi-mode and multi-state satellite monitoring, and provide real-time remote sensing data for marine target monitoring, marine environment monitoring, water resources monitoring and emergency disasters.

Due to the large number of customers using 0 1 satellite in Gaofen No.3, the load of 0 1 satellite is large, which cannot meet the needs of more customers. Gaofen-3 02 satellite was successfully reflected and put into orbit at the end of 20021. After entering orbit, 02 satellite merged with the previous 0 1 satellite to form a joint monitoring network. The monitoring range of high-scoring No.3 02 star is twice that of 0 1 star, and the data is more accurate. After the merger, the monitoring range of Gaofen No.3 network is wider, and it can also monitor the changes of the ocean, especially by adding ship positioning technology and real-time processor.

In order to better expand marine and offshore land monitoring, Gao Fen -3 03 successfully entered the scheduled orbit. With the addition of 0 1 and 02 satellites, a more advanced land and ocean monitoring satellite network has been established. Gaofen-3 network system has also become the most advanced operational satellite network in the world. Isomorphism with Beidou system forms our satellite network.
