摘要

FIELD: navigation.;SUBSTANCE: invention relates to strapdown inertial navigation systems (strapdown INS). Claimed invention is a strapdown INS, comprising an inertial monoblock made with at least one sealed cover, and a mounting frame provided with fixing elements for securing monoblock on mounting frame, monoblock body has on outer surface at least one handle for monoblock transfer and movement in mounting frame, as well as connecting elements for electrical connection of functional elements strapdown INS with external devices, wherein said functional elements are arranged inside inertial monoblock and are made in form of interconnected SU, sensor signals converter, at least one computer, as well as a secondary power source, wherein according to the invention, the inner cavity of the inertial monoblock comprises first and second compartments separated by a partition wall, wherein in the first compartment there is an SU, made in the form of a single cube-shaped body with caps sealed by means of covers with four cavities, wherein in three mutually orthogonal cavities there are rectangular ring lasers with functional electronics of the laser gyroscope, and in the fourth one, there are high-voltage voltage source, device for controlling perimeter and control of laser gyroscopes, as well as a unit of three accelerometers arranged in a single rigid housing, which when fixed in SU parallelism of axes of sensitivity of accelerometers and ring lasers, wherein housing SU is closed from outside with magnetic shields and is equipped with shock absorbers for attachment to walls of inertial monoblock, and in the second compartment there are installed the secondary power source, transducer of signals of sensors and at least one computer, at that in sealed cover of the inertial monoblock tightly closing detachable hatch is made.;EFFECT: reduction of weight and size parameters of strapdown INS at improvement of accuracy of formation of output information of the system, simplification of access to technological connector of calculator of inertial navigation system in order to simplify process of planned calibration of strapdown INS.;19 cl, 23 dwg
