This paper aims to present an attitude determination and control system for a nano-astrometry satellite which requires precise angular rate control. Focus of the research is methods to achieve the requirement.

    Design/methodology/approach

    In order to obtain astrometry data, the satellite attitude should be controlled to an accuracy of 0.05°. Furthermore, attitude spin rate must be controlled to an accuracy of 4×10−7 rad/s during observation. In this paper the following unique ideas to achieve these requirements are introduced: magnetic disturbance compensation and rate estimation using star blurred images.

    Findings

    This paper presents the feasibility of a high accurate attitude control system in nano- and micro-satellite missions.

    Practical implications

    This paper presents a possibility of the application of nano-satellites to remote-sensing and astronomy mission, which requires accurate attitude control.

    Originality/value

    Originalities of the paper are the methods to achieve the high accurate attitude control: magnetic disturbance compensation and angular rate estimation using star images.
