The DUP-4ME angular-displacement sensor is designed for measurement of angular rate of rotation of an object about the measuring axis in inertial space. The DUP-4ME operates in four-frequency mode eliminating a significant part of the zero drift errors. The DUP-4ME has the EK-104SE laser gyro sensor, the RS-485 interface card, and it is made in hermetic and non-hermetic versions.
