Abstract
HY-2A is China's first ocean dynamic environment satellite, and it is currently the only one satellite which is capable of all-weather, all-day synchronous access to the global sea surface altitude, available wave altitude, sea wind field, sea surface temperature, atmospheric water vapor, cloud liquid water and other remote sensing data. HY-2A satellite equips four kinds of active and passive microwave remote sensing load, adopts a new remote sensing system, realizes the localization of key parts and has certain characteristics of precision orbit determination, electromagnetic compatibility and high precision attitude control. As the first comprehensive type microwave remote sensing satellite, the realization of HY-2A engineering is significant. This paper is introduced about the aspects of system composition and functions, development stage, large-scale test, in-orbit test and application results show.
