DFH-50

 2000-050A


ZY-2 was a domestic remote sensing satellite developed by CAST. It has 3-meter resolution. The satellite was flown into a 474 x 493 km orbit, much lower than ZY-1. In 2001, Bill Gertz of the Washington Times reported that the civilian ZY-2 name was a cover for the Jianbing-3 imaging military reconnaissance satellite.

The ZY-2 adjusted its orbit on a regular basis, keeping it within a few km of its operational altitude.

The Phoenix Eye 2 bus, 1.8 x 2.0 x 4.6m, with a 1200 kg payload capacity, may be the spacecraft used for ZY-2.
