HY-1

Chinese earth land resources satellite. Operational, launched from 2002.05.15 (Hai Yang 1). Oceanograpy satellite built by DFH Satellite Co. Ltd of CAST for CAST, China. Launched 2002 - 2007. Used CAST968B Bus.

The Haiyang-1 (HY-1 or Ocean-1) satellite was equipped with a 10-band IR ocean color scanner and a 4-band CCD camera and was designed to end China's reliance on foreign satellites for marine observation. A total of five HY-1's were planned, with one launch every other year through 2010.

The Chinese Academy of Space Technology (CAST) announced on 11 August 1998 that it was developing a small satellite bus (CAST968) for science and earth observation missions. The first two satellites based on this bus were to be the Shijian-5 (SJ-5) and Haiyang-1 (HY-1 or Ocean-1). Both satellites would weigh 340 kg and had two solar panels. HY-1 was to be equipped with a 10-band IR ocean color scanner and a 4-band CCD camera. HY-1 completed a major design review in July 1999 and an electronic test model of the spacecraft was delivered in late 1999. In October 2000 China announced that the HY-1 would launch during 2001. China's National Ocean Administration was to build two ground stations for HY-1: one in Sanya, Hainan Island, the other near Beijing.
