Inertial Navigation Referred to the Free Surface-VII : Strapped Down Mechanizations (2)

Abstract

This is a continuation to the preceding report VI, and treats the following three items: (1) Theory of the type I (1SD) mechanization. (2) Theory of the type IN (SD) mechanization. (3) Theory of sign monitoring of a^n_x (the east-west component of specific force vector α). Items (1) and (2) involve the methods of calculating the geographic coordinates, and item (3) is related to all three mechanizations hitherto described, namely, those of types NS (SD), I (1SD) and IN (SD).
