public class TurnAroundRange extends GroundReceiverMeasurement<TurnAroundRange>
The measurement is considered to be a signal: - Emitted from the primary ground station - Reflected on the spacecraft - Reflected on the secondary ground station - Reflected on the spacecraft again - Received on the primary 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.
