Abstract. It is well-known that gyroscope base vibration as usual has a bad influence on accuracy of gyroscopic instruments and systems. During running and testing gyroscopic instruments are exposed to translational vibration, the accuracy and reliability are reducing. With rising demands on the accuracy and reliability of the gyropendulum systems, the problem of finding effects of vibration methods of research base and the possible ways to fix it remains relevant. The purpose of this paper is to present the results of experimental research of vibration influence on the gyropendulum, by using new term "vibration force". Two main regimes were tested: upwards and down displaced centre of mass of gyropendulum.

Abstract. The paper presents numerical simulations of the tape winding current impact on the motor's torque curve. The tape winding is a novel type of a motor's stator organization, allowing the large current flowing through the winding. Consequently the main flux of the permanent magnets changes. The estimation method of the developed torque dependence over the rotor and stator angular position is shown. Taking into account the control current effect the dependence is deformed, in particular it rotates relatively to the center.

Abstract. The paper presents a configuration of the modern personal navigation system and a new method of calculation of the distance traveled. The proposed navigation system is used to estimate a person's position and consists of three micromechanical gyroscopes: two at the knee and one at the waist. The knee attached gyroscope gives the distance traveled information, and the waist attached gyroscope gives the heading information. During the leg movement, the angular displacements of knees repeat at each period (each step of the walking person). By summing up all the stride lengths, the distance that a person has walked can be determined.
