The launch of Beidou-3M17 and Beidou-3M18 took place from the LC2 Launch Complex of the Xichang Satellite Launch Center, Sichuan province, using a Long March-3B/YZ-1 (Chang Zheng-3B/YZ-1) launch vehicle. Launch time was 18:00UTC and it took over four hours to complete the mission.

Also designated Beidou-42 and Beidou-43, the MEO satellites are the Medium Earth Orbit component of the third phase of the Chinese Beidou (Compass) satellite navigation system. The satellites are part of a fleet that will expand the system to a global navigation coverage.
