Galileo Radio Science investigations utilized instrumentation with elements on the spacecraft and at the Deep Space Network (DSN). Much of this was shared equipment, being used for routine telecommunications as well as for Radio Science. The performance and calibration of both the spacecraft and tracking stations directly affected the radio science data accuracy, and they played a major role in determining the quality of the results. The spacecraft part of the radio science instrument is described immediately below; that is followed by adescription of the DSN (ground) part of the instrument.
Radio Science investigations were carried out by two teams.
The Celestial Mechanics Team, under Team Leader John Anderson, conducted experimental tests of general relativity (including searching for gravitational waves), made measurements to improve solar system ephemerides, and sought to improve gravitational models for Jupiter and its satellites [ANDERSONETAL1992]. The Radio Propagation Team, under Team Leader Tay Howard, investigated the solar corona and carried out various studies in the Jovian system primarily concerningatmospheres and ionospheres [HOWARDETAL1992].
