Experience in Determining the Period of an Artificial Earth Satellite Based on Observations from One Station,

Abstract

The observation of two passages of a satellite through a celestial equator or arbitrary parallel can be used to determine the satellite's quasi-draconic period. The period of the Echo 2 balloon was determined in this way by means of a cinetheodolite at the satellite station 1101 in Sofia. The method used for treating the observations is described. An analysis of the preliminary results shows that they can be used to determine density changes in the atmosphere.
