An evaluation was achieved by designing a matlab program to solve Kepler’ s equation
of an elliptical orbit for methods (Newton-Raphson, Danby, Halley and Mikkola). This …

The objectives of this paper are twofold:(1) to present a new method of approximation such
that the function and some of its derivatives are simultaneously approximated; and (2) to …

In this paper a new method of numerically solving ordinary differential equations is
presented. This method is based on the Gaussian numerical integration of different orders …

The precision of numerical orbit integration is crucial in precise orbit determination and
gravity field recovery, especially in the context of future satellite gravimetry missions where …

Multistep methods for the numerical solution of ordinary differential equations are an
important class of applied mathematical techniques. This paper is motivated by recently …

Water is one of the most important components of the environment, having a direct effect on
