LASER GYROS

POLYUS Research & Development Institute is the leading manufacturer of ring laser sensors and laser gyros in Russia. Research and developments are carried out in two main areas:
- medium accuracy systems with stability of 0.1 to 1.0 deg/h;
- high accuracy systems with stability 0.01 deg/h;

KM-11-1A Laser Gyro 

KM-11-1A is designed as a unit with a built-in ring laser, dither, complete life support set and output signal amplifiers. The gyro outputs has two sinusoidal signals with amplitude of 2 V, which frequency corresponds to angular speed.

The KM-1-1A Laser Gyro can be used for precision navigation systems, system of spatial orientation, precision goniometers and strapdown INS for civil aircraft. The KM-1-1A Laser Gyro is certified for Il-96-300 and TU-204 airplanes.
