Abstract: The orbit determination difference between space target and controllable vehicle are compared and analyzed, the solar wing orientation mode and it′s influence to orbit is discussed. The Fourier transform of distance from space target to center of earth is chosen as key parameter if the earth station orbit measure data is limited on distance, azimuth and elevation. The calculation step is given to identify the space target solar wing orientation mode. Two case is simulated and the feasibility is verified for near earth sun synchronize orbit and geostationary orbit.
