Position Determination Experiments by the Navy Navigation Satellite System

Abstract

Position Determination Experiments by the Navy Navigation Satellite System have been made at the Electronic Navigation Laboratory since fall 1969. First, this paper describes frequencies and modulation forms of signals transmitted by satellites. The paper also gives the outline of recieving equipments used by the Laboratory and the method of caluculation for posion fix. The results of the experiments during 24 hours and one month are shown in Figures 10 and 11. The RMS error of position determinations was about 600 meters.
