The constellation of land-sea radar satellite was formed and Gaofen-3 03 was successfully launched.

On April 7, 2022, Gaofen III was successfully launched for 03 times. This satellite was launched from Jiuquan Satellite Launch Center in China. The rocket used for launching is the Long March 4 C-38 carrier rocket. According to public information, after the successful launch of Gaofen-3 03, it will form a networking operation trend with Gaofen-3 and Gaofen-3 02 which were previously launched and in orbit, that is, form a constellation of land and sea radar satellites. Through the networking and cooperative work of these three satellites, the resolution of observing the earth has reached 1 meter. When observing the earth, a target on the ground can be revisited in 0.2 days. Through higher precision and shorter interval, stronger observation effect on land and ocean can be realized, and the observation ability of radar satellites in China can be effectively improved.

According to public information, it is different from the previous 0 1 02 satellites. This time, Gaofen-3 and Gaofen-03 satellites have more powerful technical blessing and added an automatic ship identification system, namely AIS. At the same time, as the scientific load of the 03 satellite, scientists also optimized the system to make its performance more powerful. Combined with the above-mentioned high-precision and short-interval earth observation ability, the ship's observation ability to the sea surface will be improved as never before.

According to the preliminary planning of China Aerospace Science and Technology Corporation, the total number of Gaofen-3 satellites is three, which means that with the successful launch and on-orbit operation of No.03 satellite, the launch mission of Gaofen-3 satellite has been a complete success, and the three satellites have formed a real "skynet" in space.

From Gao Fen -3 0 1 to 03, three satellites were successfully launched and networked. Three satellites are evenly distributed around the earth in space, and all three satellites orbit the earth for 99 minutes. Through this networking mode, the single continuous imaging time of the global continuous ocean exploration observation mode has been extended by 1 times, and a world record has been successfully set. One network with three satellites can photograph the world ocean near 1/5 at one time, but the ability is not strong.
