Planetary Radio Astronomy (PRA)

NSSDC ID: 1977-076A-10
Mission Name: Voyager 2
Principal Investigator: Dr. James W. Warwick


This experiment consisted of a sweep-frequency radio receiver operating in both polarization states, between 20 kHz and 40.5 MHz. The signal was received by a pair of orthogonal 10-m monopole antennas. The physics of magnetospheric plasma resonances and of nonthermal radio emissions from these planetary regions was studied by investigation of the radio emission signals from Jupiter and Saturn over this range of frequencies, and similar studies will be done at Uranus and Neptune.
