Abstract
Additional test cases using a precision special perturbations program employing either Cowell's method or a variation-of-parameters method to compute an elliptical orbit are analyzed to determine which method is more efficient. The results obtained indicate that the variation-of-parameters method with a predict-only integrator and Cowell's method with a predict-partial-correct integrator are equally efficient and both are significantly more efficient than Cowell's method with a predict-correct integrator. Either of these two methods for computing precision satellite orbits offers the potential for reducing the total costs of computations during orbit design and computer execution time during real-time mission operations for future orbiter projects.
