INSTRUMENT: RADIO SCIENCE SUBSYSTEM
SPACECRAFT: VIKING ORBITER 2
Instrument Information
======================
Instrument Id : RSS
Instrument Host Id : VO2
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.
