Propagator
, PVCoordinatesProvider
public class DeepSDP4 extends TLEPropagator
The user should not bother in this class since it is handled internaly by the
TLEPropagator
.
This implementation is largely inspired from the paper and source code Revisiting Spacetrack Report #3 and is fully compliant with its results and tests cases.
