INSTRUMENT: RADIO SCIENCE SUBSYSTEM SPACECRAFT: VIKING ORBITER 1 Instrument Information ====================== Instrument Id : RSS Instrument Host Id : VO1 Instrument Name : RADIO SCIENCE SUBSYSTEM Instrument Type : RADIO SCIENCE Instrument Description ====================== The Radio Science Subsystem (RSS) was used to support the radio science investigation. This investigation utilizes the radio signals to and from the spacecraft to obtain a variety of information. Transponders on the spacecraft send back signals that are coherent with those received from earth so that precision Doppler and ranging measurements can be made. The downlinks from the spacecraft include two coherent frequencies (S band and X band) so that dispersion in the interplanetary medium can be measured and corrected for. Science Objectives ================== From analysis of the radio signals a surprising diversity of informatin can potentially be obtained and the Radio Science Team has identified a large number of scientific objectives, which fall into three categories: dynamical, surface, and internal properties of Mars, atmospheric and ionospheric properties of Mars, and miscellaneuos solar system properties.
