PURPOSE:To provide the initial capture system for a light beam which is used for inter-satellite communication and can deal with two-dimensional control. CONSTITUTION:A self-capture visual field and two-dimensional initial capture range are so determined that the visual fields of a self-defect satellite and a target satellite overlaps spatially by taking the estimated orbit error and posture error between both satellites and the bearing error of an antenna into consideration. The center of the capture visual field is captured by setting the relative angular speed with the target satellite calculated from the estimated orbit and speed of the target satellite in the initial capture range c at zero and executing raster scan at a prescribed scanning speed to overlap the capture visual fields of both satellites. |
