Abstract

Algorithms of an initial adjustment and calibration of strapdown stabilized gyrocompass on the basis of an

electrostatic gyroscope and the block of micromechanical gauges are considered. Characteristic feature of the

considered decision of an initial adjustment and calibration in start-up is total error estimation of an electrostatic

gyroscope. The equipments of satellite navigating system given to a reception with the carried aerials and the

inertial block on micromechanical gauges are involved as the reference information. Thus, the virtual ("ideal")

electrostatic gyroscope used as the basic is formed. Algorithms are generated on the basis of generalized Kalman

filter with a feedback along condition vector.

Keywords: stabilized gyrocompass, electrostatic gyroscope, micromechanical inertial sensors, satellite navigation systems, calibration.
