DEFINITION OF ORBITAL TELESCOPE ORIENTATION ON THE BASIS OF ON-BOARD MEASURING DATA PROCESSING
Quality of the information received by the systems of the Earth remote sensing depends sufficiently on the evaluation precision of the orbital telescope angular attitude. Stellar sensors are at that principal measuring instruments. Precise definition of mutual orientation of the coordinate systems connected with optoelectronic devices and stellar sensors is needed for highly accurate gridding of space photographs. On-board information processing algorithm elaborated to compensate alignment errors and temperature instability, is proposed. It allows to obtain uniformly in three axes precise orientation of the telescope, as well as to carry out subsequent calibration consisting in calculation of adjusted values of the stellar sensors mutual orientation on the apparatus that would support the error values on a minimal possible level. Navigation and operational data have to be taken into account in order to increase accuracy of binding the object to the earth location
