SEA DEVELOPMENT OF A STRAPDOWN INERTIAL NAVIGATION SYSTEM BASED ON LASER GYROS

摘要

Special features of implementing the modes of operation of strapdown inertial navigation system (SINS) under sea application conditions are considered. The above-mentioned SINS based on laser gyros has been the object of our studies. Approaches to the raising of the accuracy characteristics of such SINS are proposed, which are based on the use of geophysical invariants and on the integrated processing of the appropriate observations. The results of natural development of the SINS presented in this paper are given and analyzed.
