Abstract:
The article represents the algorithm of attitude determination in gradiometer coordinate system with respect to inertial space. The problem can be solved in two steps. The first step is to determine the values of matrix transformation from celestial system (ICRF) to star camera coordinate system (SSRF) using observations star. The second step is to determine the values of matrix transformation from star camera coordinate system (SSRF) to gradiometer coordinate system (GRF). This problem is solved through mounting sensor systems on board of a satellite. Due to the mission GOCE three star cameras are mounted there. The matrix of transformation from star camera coordinate system (SSRF) to gradiometer coordinate system (GRF) is determined for every star camera. The values of transformation matrix are represented in file of data AUX_EGG_DB. Processing star camera’s (star cameras’) observations include the following steps: making observations through star camera (star cameras); the identification of stars in the space image; the measurement of the star's coordinates in space image; the reduction of star's coordinates for time observation; the determination of matrix transformation from coordinate system ICRF to coordinate system SSRF. In the paper the algorithm of realizing the fifth step of this sequence is represented.
