getEmitterToReceiverVector

protected Vector3D getEmitterToReceiverVector(Frame frame,
                                              Vector3D receiverPosition,
                                              AbsoluteDate receptionDate,
                                              PVCoordinatesProvider emitter,
                                              AbsoluteDate approxEmissionDate)

Compute emitter-to-receiver vector.

Parameters:

frame - frame where receiver position is given

receiverPosition - receiver position in input frame at reception time

receptionDate - signal reception date

emitter - signal emitter coordinates provider

approxEmissionDate - guess for the emission date (shall be adjusted by signal travel time computer)

Returns:

emitter-to-receiver vector
