2, Launch Sites

Jiuquan Satellite Launch Center (JSLC) is located at the Gobi desert in the northwestern China. It is the earliest and largest satellite launch center in China. It is mainly used to launch medium and low orbit spacecraft with high inclinations. With its favorable natural environment, complete and reliable processing, launching and up-range instrumentation facilities and systems, more than 20 satellites have been launched from this center.

Xichang Satellite Launch Center (XSLC) is located in the green mountains of Sichuan province, southwest of China, it is mainly used to launch geostationary spacecraft. All the domestic communications and 8 commercial satellites were launched from XSLC. It has two launch pads, one for LM-3 and the other for LM-2E and LM-3A. XSLC is an advanced launch site with well-equipped launch vehicles and spacecraft testing buildings, SPM processing buildings and necessary auxiliary facilities.

Taiyuan Satellite Launch Center (TSLC) is located at the central loess plateau in the northwest of Shanxi province of China. It is the 3rd satellite launch center in China. This center is mainly used to launch sun-synchronous satellite, such as the resource satellites, meteorological satellites or Low Earth Orbit (LEO) satellites with high inclinations on LM-4 series launch vehicles.
