Description : These class of intermediate orbit satellites is similar as the BD-3 I (Type 2) satellites also built by CAS. As they have no apogee propulsion system, they require the launch vehicle to perform the final orbit insertion.
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.
