Abstract
The Chinese first Ocean satellite (HY-1) is an experimental and operational satellite for
detecting ocean color and sea surface temperature. It was successfully launched on 15 May,
2002. The payloads on satellite include a 10-band Chinese Ocean Color and Temperature
Scanner (COCTS) and a 4-band CCD imager. There are two ground stations composed the
HY-1satellite ground application system in Beijing and Sanya. HY-1 satellite is the beginning of
a new era of china’s ocean remote sensing and also ended the history of no ocean-satellite in
China. It has operation near two years and used widely for marine environmental monitoring.
This paper introduced the HY-1 Satellite, ground application system, operation and its
application.
1. Introduction
The HY-1 satellite was successfully launched on 15 May 2002[1]. Ground stations in Beijing
and Sanya, on 29 May, received the first orbit images. After in-orbit testing and process, we
obtain ocean-color data for primary production, coastal zone changes and environmental
monitoring of the China Sea.
