AIS-402 laser gyro inertial unit
The AIS-402 laser gyro inertial self-contained measuring unit is designed for measurement of angular rates of rotation and linear accelerations of a mobile object in inertial space. The AIS-402 consists of the МТ-402МE triaxial Zeeman laser gyro, the АK5-50А(М) or DА-16 (DА-17, DА-15) accelerometers, the interface card (RS-232C, RS-485) and is connected directly to computer. USB and Ethernet may be set on a customer’s demand. The AIS-301 systems based on the MT-300 gyro can be made.
