High score-1 satellite parameters

The parameters of Gaofen-1 satellite are as follows:

Track height: 645 km, track inclination: 98.0506 degrees. The local time of intersection is 10:30AM, and the regression period is 4 1 day.

Gaofen-1 satellite

Gaofen-1 satellite was developed by Aerospace Dongfanghong Satellite Co., Ltd., a subsidiary of China Aerospace Science and Technology Corporation. As the first star of China's high-resolution Earth observation system, Gaofen-1 satellite shoulders the mission of localization of China's high-resolution civil remote sensing data, and its main users are the Ministry of Land and Resources, the Ministry of Agriculture and the Ministry of Environmental Protection.

The design life of the satellite is 5-8 years, breaking through key technologies such as optical remote sensing with medium and high resolution, multi-spectrum and wide coverage, and reaching the leading level of civil optical remote sensing satellites at home and abroad in comprehensive indicators such as resolution and width. On April 26th, 20 13, 12: 03, the Long March II carrier rocket dragged the crimson flame across the sky and stabbed the pale corner.

About 765 seconds later, the satellite and arrow separated, and the first satellite of China's high-resolution Earth observation system, Gaofen-1, was accurately put into orbit, and the three foreign microsatellites carried on it were successfully separated. China's first four-star launch with one arrow was a complete success.

2065438+On March 3, 20081day, Gaofen-1 02, 03 and 04 satellites were successfully launched as the first batch of operational application satellites for the national civil space infrastructure planning. It is the first civil high-resolution optical service constellation in China, which can be used for land and resources investigation, monitoring, supervision, emergency and other major businesses, and can serve industries such as environmental protection, agriculture, forestry, ocean, surveying and mapping.
