A CONNECTED LEAST-SQUARES ADJUSTMENT OF NAVIGATION DATA

An algorithm is described that will determine the position of a ship in the least-squares optimal sense, given infrequent and irregularly spaced estimates of the ship's position and information on the ship's attempted course and speed. The requirements imposed on the solution are: (1) that it be continuous; (2) that it be continuous in the first derivative except at points of ordered intentional speed and course change (e.g., eliminating fictitious discontinuities in the Eotvos correction for gravity data); and (3) that it accommodate short-period small adjustments to an overall course.
