TAIYUAN SATELLITE LAUNCH CENTER, China (CASC PR) — On June 11 at 11:03 a.m., the Long March 2D carrier rocket launched the Beijing 3 satellite from the Taiyuan Satellite Launch Center. The booster also carried three secondary satellites: Haisi 2, Wangwang 1 and Tianjian Space Test No. 1. All four satellites entered the planned orbit, and the launch was a complete success.

The Beijing-3 satellite is an agile optical remote sensing satellite developed by the China Aerospace Science and Technology Group Co., Ltd. 5th Academy Aerospace Dongfanghong Satellite Co., Ltd., which can quickly obtain high-quality, high-resolution, and high-precision ground imagery, greatly improving my country’s commercial remote sensing satellite technology Level.

After the satellite is successfully launched, it can provide a large number of high-resolution remote sensing satellite data and information products for the global market, and provide spatial information support for land and resources management, agricultural resource surveys, ecological environment monitoring, and urban comprehensive applications.

The Haisi-2 satellite is a micro-nano optical remote sensing satellite with the objective of observing the ecological environment of coastal shallow waters and inland water bodies, which is jointly invested and developed by the Fifth Academy of Aerospace Dongfanghong and Xiamen University.

The Wangwang-1 satellite was developed by Shenzhen Aerospace Dongfanghong Satellite Co., Ltd. of the Fifth Academy. It is the first commercial astronomical satellite in the optical band in China, and carries the payload of visible light and ultraviolet large field of view astronomical telescope.

The Tianjian Space Test No. 1 satellite was developed by the 805 Institute of the Eighth Academy. It is mainly used by the Aerospace Engineering University to carry out the test verification of the new technology of satellite intelligent health management based on fault injection and serve related teaching and training.

The Long March 2D carrier rocket was developed by the Eighth Academy of Aerospace Science and Technology Group. It is a normal temperature liquid two-stage carrier rocket with single-satellite and multi-satellite launch capabilities with different orbital requirements.

For the first time, the test team used the eight-institute carrier rocket launch site digital management system to fully integrate on-site work records and quality verification systems using digital means to achieve the full process, full cycle, and full element digitization of the launch site’s work. Refined online management.

This mission is the 373rd launch of the Long March series of carrier rockets. (Wu Yahan)
