DEVICE FOR initial alignment gyrostabilized platform

摘要

Estimated useful model can be used in the construction of automatic preparation and control devices of inertial navigation systems of mobile objects. The utility model can increase the accuracy of the exhibition gyro platform inertial navigation systems with respect to the horizontal plane, by eliminating the gyro unit of errors and reduce the initial alignment error, due to the fact that the proposed device allows during the exhibition gyroplatform multiple measurements of its initial position followed by that in the final ultimately increases the accuracy of the gyro platform of the exhibition, in addition, in the course of the exhibition gyroplatform determined value of the scale coefficients of accelerometers placed on it that extends the functionality of the device and reduces setup time inertsialnoy navigation system as a whole, combining the operations of the exhibition gyroplatform and determining the scale factor of the accelerometer time. To this end the device start exhibition the gyrostabilized platform comprising a stabilized platform 1 triaxial gyrostabilizer with rigidly fixed thereto accelerometers 2, amplifier 6, rotation of the engine and caging 7, the outputs of which have a mechanical connection with a stabilized platform 1, and inputs connected to the output line of the amplifier 6 , introduced computing unit 5, the exchange unit 4 and alignment, the angle sensor 3 arranged on a stabilized platform 1, the outputs of which are connected to the output bus unit exchange and coordination 4, a second input bus which is connected to the accelerometer outputs 2, and the third input bar - to the outputs vychislstelnogo device 5, the input bus which is connected to the output bus sharing and matching unit 4, the second output bus which is connected to an input bus amplifier 6.
