Predicted Orbit Plots on Microfilm


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

Time span: 1973-10-29 to 1979-12-31


This data set, on 16-mm microfilm, contains plots of predicted spacecraft positions in each of three coordinate systems for each orbit of the spacecraft. The plots show the spacecraft orbit: (1) rotated into the GSE X-Y plane; (2) projected onto the GSM Y-Z plane; and, (3) plotted in magnetic latitude vs. magnetic local time. The GSE plot also shows the average position of the bow shock and the magnetopause, and the GSM plot shows the model neutral sheet GSM Z values at 0, 4, 8, 12, 16, and 20 hours UT averaged over the days of the plot. On each plot there is an independent set of about 20 numbered ticks drawn on the curve, and a listing of time and position information for each tick is given below the plot. The listing on the GSE plot includes the spacecraft latitude, and those on the GSM and magnetic coordinate plots include the spacecraft geocentric radius. These plots and listings were generated at NSSDC.
