A computing method of three-dimensional position fixing using a least square method to determine the optimum antenna height from satellite passes data was studied. This paper describes a systematic error mainly caused by the effect of atomospheric Doppler errors appeared in two-dimensional fixing, and presents the comparison of ten different computing methods for three-dimensional position fixing. The following conclusions were drawn from this study ; 1) The error that occurs in the path of propagation of a electromagnetic wave can deals with as a systematic error. 2) The results of each computing method differ from another more or less, however, by the introduction of a systematic error, these results approach each other. 3) These accuracies are about several meters for the determinations of latitude, longitude, and antenna height by 100 satellites passes.
