FieldImpulseProvider<T>

public class FieldCircularizingImpulseProvider<T extends CalculusFieldElement<T>>
extends FieldAbstractInPlaneImpulseProvider<T>

Class modelling impulsive maneuvers to make the orbit circular i.e. setting the osculating eccentricity to zero. The impulse vector is computed in the same frame as the orbit. The resulting osculating semi-major axis depends on the execution location. The instantaneous orbital plane is left unchanged. A constraint on the maximum magnitude can be optionally set.

Since:
