Jupiter Occultation, Merged Occultation Data

NSSDC ID: PSPA-00347

Availability: At NSSDC, Ready for Offline Distribution (or Staging if Digital)

Time span: 1979-03-05 to 1979-07-10

Ancillary data are not needed for the proper use of these data

Description

These experimenter-supplied, merged occultation data are on ASCII magnetic tape created on a Data General Eclipse S/250 computer. The data are blocked with nine 80-byte logical records per physical record. There are two file types, one containing trajectory information and the other radio frequency information. The trajectory file consists of three header records followed by five data records per time tag as follows: number of time points in file; spacecraft no.; ephemeris time (s); approximate one-way light time (s); sun position; and spacecraft and earth position and velocity. The radio frequency file consists of four header records followed by two data records per time tag as follows: number of time points in file; spacecraft no.; receiving station no.; spacecraft oscillator frequency (Hz); year and day of year; seconds past midnight; S-band received and residual frequency (Hz); S-band received power (dB); X-band received and residual frequency (Hz); and X-band received power (dB). All position and velocity vectors are Jupiter-centered in the earth-mean-equator 1950 coordinate system.
