BD-3M 3S [CAS]
BD 3M (Beidou 3M) satellites are the MEO component of the 3rd phase of the chinese Beidou (Compass) satellite navigation system, which, in contrast to GPS and GLONASS, uses both geostationary satellites and satellites in intermediate orbit.
This series provides the satellites for the intermediate constellation called "Compass-M" in 12-hours orbits. Ulitmately, the MEO constellation will comprise 27 satellites.
These class of intermediate orbit satellites is similar as the BD-3 I (Type 1) satellites also built by CAS. As they have no apogee propulsion system, they require the launch vehicle to perform the final orbit insertion.
The third phase MEO satellites can be launched as single stellites on a CZ-3C/G3Z with additional dispenser stage, two at a time on a CZ-3B/G3Z with additional dispenser stage or four at a time on a CZ-5 with additional dispenser stage.
