Summary
Beidou-3 M7 & M8 launched on a China Aerospace Science and Technology Corporation Long March 3B/YZ-1 from Launch Complex 3 (LC-3/LA-1), Xichang Satellite Launch Center, People's Republic of China on January 11, 2018. It was China Aerospace Science and Technology Corporation's 209th launch, 2nd this year and humanity's 5,709th orbital launch attempt. It was the 3rd Long March 3B/YZ-1 flight and the 1st this year. The payload was bound for Medium Earth Orbit (MEO). Beidou DW 26, one of 4 catalogued objects, reached a 21,538 × 22,200 km orbit inclined 55.0°. 4 objects from this launch are catalogued, 2 of them payloads.

About this launch
The BeiDou Navigation Satellite System (BDS) is a Chinese satellite navigation system. It consists of two separate satellite constellations – a limited test system that has been operating since 2000, and a full-scale global navigation system that is currently under construction. Beidou-3 are the third generation of navigation satellites which are launched into medium Earth orbit.
