Orbit Determination

Scientific paper

With an a priori value of the orbital element e or a, an iterative algorithm to determine the initial orbit, using the short-arc angle data, is investigated. An a priori value of orbital element can be regarded as an observation with proper precision, and the residual term corresponding to the observation of e or a can be put in the weighted square sum of residuals. Minimizing the weighted square sum of the residuals, the iterative algorithm of initial orbit determination with the a priori value of e or a is derived. In fact, this method is an iterative algorithm of the least square estimation. Simulations show that the accuracy of the orbital period mainly depends on the precision of the a priori value of eccentricity e. When the eccentricity e is small enough, the semi-major axis a' estimated with circular orbit may be regarded as the a priori value of the orbital element a. Then, using the above algorithm with the a priori value of the semi-major axis a, the result of initial orbit can be got with high accuracy.
