Constellation networking technology _ What is a constellation network?

Is the first civil optical service constellation networking successful in China?

On March 3,1day, 1 1: 22, Gaofen-1 02, 03 and 04 were successfully launched in Taiyuan Satellite Launch Center, which marked the success of the first civil high-resolution optical service constellation network in China and will greatly improve the efficiency of earth observation. Xi 'an Branch of the Fifth Academy of Aerospace Industry, located in Xi 'an, provided a data transmission subsystem for these three satellites, which opened up a green channel for the smooth transmission of satellites and other data back to the ground.

Gaofen-1 satellite is the first satellite of Gao Fen special project, which has medium and high resolution and wide imaging capability. It has a wide field of vision, covering 800 kilometers at a glance and observing the earth completely in four days. Now, with the addition of 02, 03 and 04 satellites of Gaofen-1, it will be networked with Gaofen-1 0 1 3 launched by 20 13 to form a high-resolution optical remote sensing satellite constellation with 2m panchromatic and 8m multispectral images for earth observation, which greatly improves the observation efficiency. This is the first civil high-scoring optical service constellation in China. Gaofen-1 satellite constellation will play an important role in land and resources survey, comprehensive agricultural utilization, environmental protection and comprehensive disaster reduction and relief.

It is expected that in June 2008, China will launch the Goffin-6 satellite. By then, Gaofen-6 and Gaofen-1 will be networked again to further improve the observation ability of Gaofen family satellites.
