org.orekit.propagation.semianalytical.dsst.utilities.FixedNumberInterpolationGrid

All Implemented Interfaces:

InterpolationGrid

public class FixedNumberInterpolationGrid
extends Object

Interpolation grid where a fixed number of points are evenly spaced between the start and the end of the integration step.

The grid is adapted to the step considered, meaning that for short steps, the grid will be dense, while for long steps the points will be far away one from each other
