ON PRELIMINARY ORBIT DETERMINATION: A NEW APPROACH Conference Paper

abstract

• A new approach for preliminary orbit determination based on angles-only observations is presented. The proposed technique is iterative and uses the Lagrangian coefficients f and g which is similar to the Gauss' method of orbit determination from this aspect. As opposed to the Gauss' approach, the method is not singul ar for the coplanar case. The proposed technique is finally compared with the classic iterative method of Double-r [1]. The presented techi nique is also capable of handling multiple observations for higher accuracy whereas the level of the algorithm complexity remains the same as opposed to the available methods. Also the data were corrupted with noise to simulate the true measurements. Results show our method as a valid alternative to the classical methods of orbit determination.
