S-Band Occultation

NSSDCA ID: 1973-019A-10

Mission Name: Pioneer 11
Principal Investigator:Dr. Arvydas J. Kliore


This experiment utilized the S-band (2292-MHz, 8-W) spacecraft radio transmitter signal characteristics to obtain information about the ionospheres and atmospheres of Jupiter, Io, and Saturn. Entrance into and exit from Jupiter and Io occultations provided changes in the signal characteristics from which atmospheric temperature, pressure, and electron density profiles could be calculated. Temperature and pressure profiles were limited to levels above the pressure of one earth atmosphere. Signal occultation also provided a determination of the planetary diameter.
