BD-2 G

BD-2 G2 [CAST]

BD 2G (Beidou 2G) satellites are the GEO component of the 2rd 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-3 Bus. They feature a phased array antenna for navigation signals and a laser retroreflector and additionally a S/L-band dish antenna and a C-band horn antenna.

The first satellite of this series, BD-2 G2, failed early on orbit.
