satellites include HY-1B and HY-2. CNSA is now developing the Chinese-French Oceanic Satellite (CFOSAT) with
Centre National d'Etudes Spatiales (CNES). The CFOSAT
will be equipped with sea surface wind field and wave spectrum detection instruments, which will further enhance
the monitoring capacity of ocean dynamic environment.
China's HY satellite series have long-term stable operation,
which play an important role in marine resource management and disaster monitoring (Fig. 4). HY-2 satellite, as
the main international ocean dynamic environmental satellite, has been incorporated into many international organizations operational satellite series (such as European
Organization for the Exploitation of Meteorological Satellites, EUMETSAT), and becomes the primary monitoring
means of global ocean dynamic environment.

testing activities will promote the innovative development
of China's Earth observation technology, enhance the
foundational research capability for China's satellite, and
quickly improve the satellite technology. Now, there are
remote sensors aboard the SJ-9A/B and Tiangong-1, which
carry out the Earth observation mission.
III. CONSTRUCTION OF HIGH-RESOLUTION
EARTH OBSERVATION SYSTEM
In May 2010, China launched the construction of the
CHEOS. CNSA is responsible for construction of CHEOS,
and the Earth Observation System and Data Center of
CNSA (EOSDC-CNSA) is responsible for organizing the
construction and operation.
According to the idea of integrated space-ground architecture, this major project focuses on building a new
Earth observation system with high spatial, temporal and
