Advancing Universal Algorithmic Support for High-Precision Strapdown Inertial Navigation Systems in Aircraft and Rockets

Based on the use of the Kotelnikov-Study transfer principle, a method of creating universal software and algorithmic support for high-precision strapdown inertial navigation systems (SINS) for aviation and carrier rockets is proposed. The peculiarity of universal algorithms is that high-frequency SINS orientation algorithms are proposed to be built for a geographic reference coordinate base, and estimates of the current components of speed and coordinates, and the orientation parameters of the instrument trihedron relative to the geographic base, if necessary, to be converted to a geotopical base.
