INTEGRATED orientation and navigation based on strapdown electrostatic gyros and micromechanical sensors

摘要

The invention relates to a marine navigation instrument engineering and can be used underwater vehicle control systems. Integrated system orientation and navigation on the basis strapdown electrostatic gyro and MEMS sensors comprises a measurement unit with three micromechanical gyroscopes and three accelerometers multiantennuyu receiving apparatus of the satellite navigation system, the data processing unit, strapdown electrostatic gyroscope and forming unit difference measurements, the electrostatic gyroscope output is connected to the first input of difference forming unit measurements, the second input of which is n By connecting the first output of the strapdown processing unit girogorizontkompasa, a third input connected to the second output of the data processing unit strapdown girogorizontkompasa, and the output of difference forming unit of measurement is connected to fourth input of the data processing unit. The technical result consists in improving the accuracy of the navigation data generation rate of the object during operation in the autonomous mode, without involving the external data from the satellite navigation system.
