STRAPDOWN INERTIAL NAVIGATION SYSTEM FOR HIGH-SPEED MANEUVERING OBJECT

摘要

FIELD: instrument making.;SUBSTANCE: invention relates to the field of instrument making, and may be used in development of the strapdown inertial navigation systems (SINS) for the high-speed maneuvering object. Strapdown inertial navigation system for the high-speed maneuvering object, containing angular velocity sensors and apparent acceleration sensors, connected to the on-board computer, which stores a priori information about the Earth's rotation, its gravitational field and initial conditions of the object movement, and at each current time point, six variables of inertial information, fifteen variables of navigation information and the object movement controlling function are sequentially calculated. At that, as the inertial sensors five tuning-fork type Coriolis vibratory gyroscopes with identified mass-geometry characteristics and given harmonic laws of four point masses motion in time are used, each of which suspension is installed into the reference node by means of twenty compressive non-spinning force sensors, connected to the on-board computer, in which the inertial sensors suspensions supports reactions are successively calculated, thirty inertial information variables using the redundancy to control the calculations accuracy and increase reliability; fifteen navigation information variables and the object motion control function.;EFFECT: enabling obtaining the high-speed maneuvering object accurate navigation measurements.;1 cl, 6 dwg
