IPC: G05D1/08
Filed: 1990-06-21
Abstract: PURPOSE:To use an astronomical sensor which can work in a visible light area and to simplify the constitution of the device and the data processing operation by correcting the attitude of an astronomical probe and to control the probe in a desired direction based on the astronomical image detected by the astronomical sensor and the direction of the sun detected by a solar sensor. CONSTITUTION:The directions of a roll axis 3, a pitch axis 4, and a yawing axis 5 are obtained based on the output of an inertia reference device mounted on an investigator 1. The incident direction of the sun 7 is obtained by the output of a solar sensor within a surface orthogonal to the axis 5, and an angle error signal is produced around the axis 5 from the difference between the output of the solar sensor and the incident direction of the sun that is previously stored. At the same time, only the incident side of the sun 7 is extracted as an astronimical edge and the center of this edge is obtained among the contours of a heavenly body 6 obtained from the visible light image of the body 6 photographed by an astronomical sensor against both axes 3 and 4. Then an error signal is produced around the axis 3 or 4 based on the difference between the edge center and the axis 3 or 4. The detected attitude error of the probe 1 is corrected by the error signal. Thus a sensor working in a visible light area is available, and the device constitution and the data processing operation are simplified.
