About Equations of Errors of Inertial Navigation Systems, Determining Arbitrary Curvilinear Coordinates of a Moving Object

摘要

The report discusses the perturbed motion of an inertial navigation system, when its elements have instrumental error, and the initial conditions are inaccurate. Derived are equations of errors in the determination of inertial coordinate systems of an object and parameters, characterizing its orientation in space. It is shown, how these equations can be reduced to equations of errors of inertial systems, determining Descartes' coordinates of the object. (Author)
