Методы повышения точности лазерных инерциальных измерительных блоков

Голяев Ю., Иванов М., Колбас Ю., Крутиков А., Соловьева Т. И.

The methods of increasing the accuracy of inertial measurement units (IMU) on Zeeman laser gyros and quartz accelerometers are considered. Design solutions for the rigid installation of the IMU components with the exact reference of the measurement axes and also for IMU maintainability are presented. The principles of quasifourmode Zeeman laser gyro, mathematical algorithms, providing the laser gyroscope drift compensation, and algorithms to compensate errors of the accelerometers with periodic calibration of the analog-to-digital converters are described.
