BD-3 G


BD 3G (Beidou 3G) satellites are the GEO 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, also called "Compass-G" is the geostationary constellation.

The satellites are based on the DFH-3B Bus. They feature a phased array antenna for navigation signals and a laser retroreflector and additionally deployable S/L-band and C-band antennas.
