Refined Orbit Elements at 3 Day Intervals


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

Time span: 1967-05-06 to 1970-12-13


This microfiche data set contains orbit elements at 3-day intervals. It was prepared from all available satellite observations made at the Stadan Minitrack Stations, over a 27-1/2 month period immediately after launch, and in December 1970. A few camera observations were used to supplement the original observations. The data are listed chronologically and include classical Keplerian elements. For each set of elements the following are also included: the number of observations, the observation time span, and the observation weighing factor. Documentation precedes the tables of data. See the documents R. H. Gooding, "Orbit of Ariel 3 (1967-42A)," Roy. Aircraft Estab., (RAE) TR 69275, Farnborough, England, December 1969; and R. H. Gooding, "Revised and terminal orbits for Ariel 3 (1967-42A)," Roy. Aircraft Estab., Tech Memo Space 170, Farnborough, England, July 1971, (NSSDC TRF B14888 and B14889, respectively).
