Paper Abstract

A control system, consisting of an image movement sensor and movement compensator, is used to stabilize optical image in the focal plane of a spaceborne Earth's surveillance system. After an optoelectronic sensor for such a system had been elaborated by the authors, it was shown than its precision is affected with cloud movement in the field of view of the optical system. Moreover, even moderate cloudness appears to result in untolerable measuring errors. In this paper two techniques of diminishing measuring errors due to cloud movement are presented and their efficiency is estimated.
