Proposed formula to assess the accuracy of geodetic altitudes and latitudes on the spatial rectangular coordinates. The proposed formulas allow you to define geodetic altitude and latitude as a result of satellite geodetic definitions at any point in the Earth's surface, including on the equator, the pole, the zero meridian and the meridian 180 град. The analysis has shown, that the accuracy of determination of altitudes and latitudes does not depend on the provisions of points. The accuracy of the heights is equal to the accuracy of determination of spatial coordinates (provided they are uniform accuracy), and latitudes (in arc seconds) – the accuracy of the coordinates (in meters), multiplied by the coefficient of 0,032.
