Tests of the Extrapolation Method for the Numerical Integration of the Keplerian Motion

Conference paper


Two extrapolation methods (Gragg’s method and GBS method) were tested for the numerical integration of the Keplerian motion. The tests cleared that the Gragg’s method is better for the orbit computation and is 1) easy to control, 2) highly accurate, 3) tough, 4) economic, and 5) very flexible against the close encounter.
