Aerospace Instrument-Making Annotation << Back The research of the opportunity of the usage of the depthometer system for the orientation parameters correction in the strapdown graviinertial navigation complex A.I. Chernomorsky, A.A. Afonin An opportunity of using the information from the depthometers for the orientation parameters correction of the strapdown inertial navigation system onboard a small underwater vehicle is investigated. Variants of the using of the pivoting and fixed depthometer systems and also an option of the usage for the strapdown inertial navigation system a complex consisting of the depthometer systems, accelerometer constructor of the vertical and the magnetic course system are discussed.
