Numerical integration of the equations of motion and variational equations
Abstract
The Stormer-Cowell/Adams integration processes available in GTDS for integration of the Cowell and various VOP formulations of the equations of motion are described. These processes were selected on the basis of efficiency studies comparing various classes of popular integration algorithms as applied to special perturbation techniques. Also reported is the single step Runge-Kutta integration method that is used in GTDS in connection with sequential estimation and as a starter for certain multistep processes.
