Integration of the Equation of the artificial Earth's Satellites Motion with Selection of Runge-Kutta-Fehlberg Schemes of Optimum Precision Order
For researchers in satellite dynamics and simulation modeling, this work offers a method to choose integration schemes for improved precision, but it is an incremental improvement over existing Runge-Kutta-Fehlberg methods.
The paper proposes a method for selecting an optimal Runge-Kutta-Fehlberg scheme to ensure required local precision in numerical integration of ODEs, applied to satellite dynamics. The approach shows good effectiveness and global stability in multi-variable simulation problems.
An approach is treated for numerical integration of ordinary differential equations systems of the first order with choice of a computation scheme, ensuring the required local precision. The treatment is made on the basis of schemes of Runge-Kutta-Fehlberg type. Criteria are proposed as well as a method for the realization of the choice of an 'optimum' scheme. The effectiveness of the presented approach to problems in the field of satellite dynamics is illustrated by results from a numerical experiment. These results refer to a case when a satisfactory global stability of the solution for all treated cases is available. The effectiveness has been evaluated as good, especially when solving multi-variable problems in the sphere of simulation modelling.
