A MODEL OF COSMIC TRIANGULATION BASED ON OBSERVATIONS OF ARTIFICIAL SATELLITES AT VARIOUS TIMES,

Abstract

The coordinates of observation stations are determined by the space triangulation method using the circle of simultaneity. A model of cosmic triangulation has been calculated for hypothetical satellites on the basis of nonsimultaneous observations. In this method it is not necessary to know the satellite orbit. The author solves the problem in two ways: first using three simultaneous observations of three different satellites and then using two periods of observation and the equation for the tangent plane to the ellipsoid at the point where the station is situated. In both methods, the problem can be simplified in practice by taking two observations of the same satellite, one on the ascending path and another on the descending path on two different dates.
