public abstract class AbstractInterSatellitesMeasurement<T extends ObservedMeasurement<T>> extends AbstractOnBoardMeasurement<T>
Base class for measurement between two satellites that are both estimated.The measurement is considered to be a signal emitted from a remote satellite and received by a local satellite. Its value is the number of cycles between emission and reception. The motion of both spacecraft during the signal flight time are taken into account. The date of the measurement corresponds to the reception on ground of the emitted signal.
