When was the China Resources No.3 03 satellite successfully launched?

On July 25th, at 1 13, China used the Long March 4 B carrier rocket at Taiyuan Satellite Launch Center, and successfully put Resource 3 03 into the scheduled orbit. The launch was a complete success. The mission is equipped with a lobster eye X-ray detection satellite and a sporadic apocalypse constellation.

Resource 3 03 satellite is a high-resolution stereo mapping satellite, which is developed and produced by the Fifth Academy of Aerospace Science and Technology Group Co., Ltd. and will be networked with Resource 3 02 satellite in orbit. It is mainly used to obtain high-resolution stereoscopic images and multi-spectral data, and will provide application services for geographical national conditions monitoring, land and resources investigation, disaster prevention and mitigation, agricultural water conservancy, ecological environment, urban planning and construction and other fields.

The lobster eye X-ray detection satellite launched this time is a space science detection satellite, which will verify the ultra-large field-of-view focusing imaging technology of X-ray energy segment in orbit and deeply detect the dark matter signal of X-ray energy segment; Apocalypse constellation is a data acquisition satellite, which will provide commercial data acquisition and transmission services in orbit. Both satellites are developed and produced by Shanghai Ayers Aerospace Science and Technology Co., Ltd..

This mission is the 34 1 flight of the Long March series of launch vehicles.

Add data support for 3D applications

Ziyuan-3 03 satellite runs in 505km sun synchronous regression orbit, and has the ability of multi-angle stereo observation and laser elevation control point measurement, which will further improve the mapping ability of China's 1: 50000 scale and the updating ability of larger-scale geographic information.

Compared with conventional optical satellites, Ziyuan-3-03 satellite not only provides standard surveying and mapping products such as digital orthophoto and digital terrain model, but also has the outstanding advantages of three-camera stereo observation and laser altimeter to obtain elevation control points and directly generate three-dimensional stereo images, which can provide high-precision data products for realistic stereo China construction, geographic national conditions monitoring, cultivated land protection and geological disaster prevention.

For example, in the management of cultivated land, we can not only know where and how big the land is, but also know whether the land is sloping farmland and what the slope is. Used in the investigation and monitoring of geological disaster bodies, it can not only provide geological and geographical characteristics of disaster bodies, but also quantitatively estimate key parameters such as the volume of disaster bodies.

After the operation of the 03-satellite network of Resource 3, the revisit period will be shortened from 3 days to 1 day, and the acquisition efficiency and emergency monitoring ability will be stronger. The satellite will significantly improve the ability of three-dimensional investigation of natural resources, and can also be widely used in transportation, water conservancy, emergency management, ecological environment and other related fields.
