Abstract. A method for estimation of orbit elements and spacecraft (SC) orientation parameters relative to a moving orbital coordinate system is proposed. The method is based on analysis of spacecraft axes hodograph formed with the use of astronomic measurements carried out with an optical-electronic device rigidly fixed on the SC body at known angles.
