public class TurnAroundRange extends AbstractMeasurement<TurnAroundRange>
The measurement is considered to be a signal: - Emitted from the master ground station - Reflected on the spacecraft - Reflected on the slave ground station - Reflected on the spacecraft again - Received on the master ground station Its value is the elapsed time between emission and reception divided by 2c were c is the speed of light. The motion of the stations and the spacecraft during the signal flight time are taken into account. The date of the measurement corresponds to the reception on ground of the reflected signal.

This constructor uses 0 as the index of the propagator related to this measurement, thus being well suited for mono-satellite orbit determination.
