Optimizing the Spacecraft Guidance Laws at the Earth Optoelectronic Observation
Obtained in the space photos a ground resolution depends on a spacecraft (SC) spatial angular motion during optoelectronic survey. The paper examines case of optimal equalization of an image longitudinal velocity in the focal plane of telescope and tackles the problem of defining initial azimuth of the scanning survey under the condition of minimizing quadratic functional of image cross velocity values on the left and right edges of the CCD linear array. Results of a simulated survey of random surface object are presented, and the change of initial azimuth value for various survey angles within the swath is examined. The paper presents a brief description of developed software for designing the space telescope characteristics and gives recommendations for its application.
