Allowance for differences in ellipsoids and geodetic control coordinate systems in determining ship's position using radio navigation systems
Abstract
In determining a ship's position using a satellite radio navigation system (RNS) the coordinates must be transformed from a satellite geodetic system to a local system. This problem is discussed. A table shows how the m, p, q values can be used in computing the coordinates of centers of some ellipsoids relative to the centers of others. Formulas are given for evaluating the corrections required when transforming coordinates from the WGS72 system to the Krasovskiy ellipsoid. Examples are given which show that discrepancies in coordinates in certain cases can be quite large.
