Method Detail

update

public abstract void update(Satellite sat,
                            double tsince,
                            Vector3 pos,
                            Vector3 velo)

The abstract update method implements the propagation model which, provided a satellite and a time, calculates a position and velocity for the object.

Parameters:

sat - Satellite The satellite to be propagated.

tsince - double The time at which predictions should be made.

pos - Vector3 The ECI position vector populated by the model.

velo - Vector3 The ECI velocity vector populated by the model.
