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 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.
