Method Detail

getEmitterToReceiverVector

protected Vector3D getEmitterToReceiverVector(SignalReceptionCondition receptionCondition,
                                              PVCoordinatesProvider emitter,
                                              AbsoluteDate approxEmissionDate)

Compute emitter-to-receiver vector.

Parameters:

receptionCondition - signal reception conditions

emitter - signal emitter coordinates provider

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

Returns:

emitter-to-receiver vector

getEmitterToReceiverVector

Compute emitter-to-receiver vector with FIeld.

Type Parameters:

T - field type

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
