|---|---|---|
| eVAErrorControlAbsolute | 0 | The error estimate of each integrated component is compared to the absolute error tolerance. Error control with this method is based on absolute values, e.g. in meters for position, m/sec for velocity, etc. |
| eVAErrorControlRelativeByComponent | 1 | The error estimate of each element being integrated relative to the element's value at the start of the step is compared to the relative error tolerance, and the absolute error estimate of each element is compared to the absolute error tolerance. |
| eVAErrorControlRelativeToState | 2 | The magnitude of the vector error estimate for integrated vectors (e.g. position, velocity) relative to the magnitude of those vectors, and the error estimate of non-vector elements (e.g. mass, if thrusting) relative to the magnitude of those elements are compared on an individual basis to the relative error tolerance; in addition, the magnitudes of those error values are compared to the absolute error tolerances. |
| eVAErrorControlRelativeToStep | 3 | The error estimate of each integrated component relative to the element's change in value over the step is compared to the relative error tolerance, and the absolute error estimate of each integrated component is compared to the absolute error tolerance. Error control is relative to the size of the current step of the state, e.g. delta X for X, delta Y for Y, etc. |
