e/Radio Science Subsystem

Information
has gloss	eng: The Radio Science Subsystem (RSS) on a scientific spacecraft uses radio signals to probe a medium such as a planetary atmosphere. The spacecraft transmits a highly stable signal to ground stations, receives such a signal from ground stations, or both. Since the transmitted signal parameters are accurately known to the receiver, any changes to these parameters are attributable to the propagation medium or to the relative motion of the spacecraft and ground station.
