DETERMINATION OF GEODESIC LATITUDE BY SPATIAL RIGHT-MUGAL COORDINATES BY USING A DIFFERENTIAL AMENDMENT
GNSS technologies are currently essential for coordinate support of territories. However, theymakeit possible to obtain spatial rectangular coordinates of the points being determined. While most users need the flat rectangular coordinates of Gauss - Kruger. And these coordinates can be calculated only by geodetic latitudes and longitudes. The special literature describes more than a dozen methods for calculating the geodetic latitude in spatial rectangular coordinates. To solve this problem, usually use any iterative or non-iterative methods. Both those and others have their advantages and disadvantages. In the work applied the third way to solve the problem. It is proposed to calculate and use the differential correction to the initial (approximate) value of the geodesic latitude. Received working formulas that implement this idea. A numerical example is given showing the possibility of practical application oftheproposedmethod.
