A summary of certain position information indicating accuracies for the orbital arcs underlying the ephemeris is presented in table 1. The detailed ephemeris information is presented at the end of this report in the form of tables which give the latitude and longitude of the subsatellite point and the satellite height for each minute of time. The subsatellite point is defined here as the point on the earth's surface over which the satellite was determined to be at the indicated time. The form of presentation was recommended by the International Geophysical Year agencies concerned, for use in specifying the orbital positions of IGy satellites. Time is specified by giving in columns, the day, hour, and minute of Greenwich mean time.
