ANALYTICAL MODEL OF THE DEVIATIONS IN THE COORDINATES OF THE POINTS OF A PSEUDO-FRAME, ACQUIRED BY SCANNER SURVEY OF THE EARTHS SURFACE FORTHE CASE OF A CIRCULAR ORBIT AND A SPHERICAL, NONROTATING EARTH

The paper describes the results of research to create an analytical mo del of the deviations in the coordinates of the points of a pseudo-fra me acquired in a scanner survey of the Earth's surface, in which we mo ve from a very simple to a more complete model. Previous results are e xtended to the case of a circular orbit and a spherical, non-rotating Earth. It is shown that the refining terms in the deviations are of no t less than second order relative to the increase in the orbital angle over the survey period.
