The need to combat harmful uncontrolled constant torque around the vertical axis of the sensor element (SE) GPGC led to the emergence of a number of methods involving the processing of information on the movement Jae GPGC for two starts (opposite the initial position of the main axes, with two different fixed values of the parameters of GPGC etc.). It is possible to find the position of the plane of the meridian under the action of harmful uncontrolled moment, but more than double the measurement. The goal of this study - to assess the possibility of determining both the initial deviation GPGC main axis, and the value of the time harmful for one start by analyzing information on the non-linear azimuthal motion Jae GPGC. The idea of this approach is that the time constant of control not only shifts the position of the equilibrium fluctuations, but also deforms the curve fluctuations, making it quite different from the vibrations of a single-frequency harmonics. This "non-linearity" vibrations of the device is proportional to the uncontrolled and harmful torque oscillation amplitude. Resolved differential equation of motion GPGC retention of two components in the expansion of the trigonometric functions in a number of activities subject to constant and slowly varying uncontrolled moments around the vertical axis of the SE. The resulting analytical Jae GPGC law of motion can be the basis for the algorithm for determining the plane of the meridian for one start Product Description popup.authors Федоров Володимир Миколайович popup.nrat_date 2020-04-02 Close
