Selecting an Integrator

The table below lists the numerical integrators you can use with the Attitude Simulator:

Integrator	Description
RKF 7(8)	Runge-Kutta-Fehlberg integration method of the seventh order with eighth-order error control for the integration step size
RKF 4(5)	Runge-Kutta-Fehlberg integration method of the fourth order with fifth-order error control for the integration step size
Burlirsch Stoer	Integration method based on Richardson extrapolation with automatic step size control

For the Runge-Kutta-Fehlberg integrators, you can set Relative Error and Absolute Error tolerances. You can also use minimum and maximum step sizes (i.e., the time interval between evaluations) and specify these values.

For the Burlirsch Stoer integrator, set the Relative Error tolerance and the Number of Stages (at least two).
