FIELD: physics.SUBSTANCE: universal topographic precise positioning and navigation system has a set of main and auxiliary equipment. The main equipment consists of a basic inertial navigation system, an altitude determining system and a Doppler velocity sensor. The basic inertial navigation system includes a self-contained navigation apparatus - a gimballess inertial navigation and topographic precise positioning system, navigation apparatus for satellite navigation system consumers, consisting of an electronic receiver-indicator unit and antenna module, matching unit and a universal mechanical velocity sensor. The altitude determining system consists of an atmospheric pressure digital metre, a temperature sensor and a data processing unit. The gimballess inertial navigation and topographic precise positioning system, the electronic receiver-indicator unit of the navigation apparatus of satellite navigation system consumers, the matching unit and the data processing unit of the altitude determining system have data exchange channels for communication with a hardware and software system. The universal mechanical velocity sensor is electrically connected to the matching unit and has a cable channel for connection to the chassis electrical equipment system. The shaft of the universal mechanical velocity sensor is rigidly connected to a unit for connecting the speedometer of the transfer gearbox of the chassis. The Doppler velocity sensor is connected to the matching unit. The auxiliary equipment includes a plate made from aluminium alloy and provided with mounting pads with threaded steel bushings for mounting the gimballess inertial navigation and topographic precise positioning system, a cantilever and a clamping frame for mounting the Doppler velocity sensor, having a shock-absorbing lining, with a set of adjusting washers, a post for mounting the matching unit, the data processing unit and the atmospheric pressure digital metre of the altitude determining system. The auxiliary equipment can additionally be provided with a cantilever for mounting the temperature sensor.EFFECT: design of a universal topographic precise positioning and navigation system which provides high accuracy of determining topographic and geodetic parameters and configured for use in mobile weapon systems having different functionalities.2 cl, 8 dwg |
