The Fengyun-4 (FY-4) satellite series is a new generation of geostationary meteorological satellites from China. The newly adopted three-axis-stabilized attitude-control platform can increase observation efficiency and flexibility while bringing great challenges for image navigation as well as integrated observation mode design. Considering the requirements of earth observation, navigation and calibration as well as observation flexibility, instrument observation strategies are proposed.

A flexible, effective, stable and automatic star observation strategy directly influences star data acquisition and navigation precision. According to the requirement of navigation, two specific star observation strategies for the two main instruments on board FY-4A were proposed to be used in the operational ground system. The strategies have been successfully used in FY-4A in-orbit tests for more than a year.

<jats:p>Abstract. The Fengyun-4 (FY-4) satellite series is a new generation
of geostationary meteorological satellites from China. The newly adopted
three-axis-stabilized attitude-control platform can increase observation
efficiency and flexibility while bringing great challenges for image
navigation as well as integrated observation mode design. Considering the
requirements of earth observation, navigation and calibration as well as
observation flexibility, instrument observation strategies are proposed. These include the earth, the moon, stars, cold space, blackbody and diffuser
observations on which the instruments' in-orbit daily observations must be
based. The most complicated part is the star observation strategy, while
navigation precision is dependent on in-orbit star observations. A flexible,
effective, stable and automatic star observation strategy directly
influences star data acquisition and navigation precision. According to the
requirement of navigation, two specific star observation strategies for the
two main instruments on board FY-4A were proposed to be used in the
operational ground system. The strategies have been successfully used in
FY-4A in-orbit tests for more than a year. Both the simulation results and
in-orbit application results are given, including instrument observation
strategies, star observation strategies and moon observation tasks, to
demonstrate the validity of the proposed observation strategies, which lay
important foundations for the instruments' daily operation.
