Titan Radio Occultation Data


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

Time span: 1980-11-12 to 1980-11-12


These Titan radio occultation data are on ASCII magnetic tape created on a PRIME computer. The tape contains Titan entry and exit frequncy and amplitude data, and entry and exit trajectory data. Each frequency and amplitude file contains a header with the number of data records in the file; spacecraft ID; entry, exit flag; transmitting and receiving station numbers; communications mode; and frequency bands. The data records contain time in year, day of year, and seconds past midnight; S- and X-band received RF frequency (Hz); and S- and X-band received power (dB). Each trajectory file begins with a header containing number of data records in file; spacecraft ID; entry, exit flag; file ID; transmitting and receiving station numbers; speed of light (km/s); difference between ephemeris and universal times (s); and approximate one way light time (s). Each trajectory data record contains spacecraft event ephemeris time (seconds past 1950); occulting body to spacecraft distance and velocity, earth distance and velocity, and sun distance and velocity.
