public class ConfigurableLowThrustManeuver
extends Maneuver

This class implements a configurable low thrust maneuver.

The maneuver is composed of succession of a burn interval. Burn intervals are defined by two detectors. See EventBasedManeuverTriggers for more details on the detectors. The attitude and the thrust direction are provided by an instance of ThrustDirectionProvider See ThrustDirectionProvider for more details on thrust direction and attitude.

                                     double isp)

Constructor.

This legacy constructor forbids backward propagation.

See EventBasedManeuverTriggers for requirements on detectors

Parameters:

thrustDirectionProvider - thrust direction and attitude provider

startFiringDetector - detector to start thrusting (start when increasing)

stopFiringDetector - detector to stop thrusting (stop when increasing)

thrust - the thrust force (N)

isp - engine specific impulse (s)
