Applicability of Stellar Rate for Astronomic Position Determination,

Abstract

This paper deals with a method of determining an astronomic position by using the star rate of change in azimuth and zenith distance, with respect to time. The star is observed a number of times. Coefficients of Taylor expansion, up to the third order, can be obtained with a high degree of accuracy as a function of sections of a small great circle of arc. Methods of application of observed data, time, zenith distance, and azimuth are considered. They can be reduced to an arbitrarily chosen star position. A comparison of the results so obtained gives a test of the accuracy of the observation. It is shown that astronomic refraction problems can be reduced using the method described in this report.
