Honeywell’s GG1320 digital ring laser gyros (RLG) is the industry standard for precision rotation measurement.

RLG's are critical rotation sensing elements in navigation systems for manned and unmanned aircraft, platform stabilization systems, pointing and targeting, marine navigation and attitude and heading reference systems (AHRS). The  principle of operation of an RLG is that counter-propagating laser beams have different frequencies with the difference dependent on rotation rate. Measurement of this difference provides the rotation angle or  rotation rate about the RLG's sensitive axis. One can thus determine the orientation of a system in inertial space at all times.

Key Benefits

The Honeywell GG1320AN digital ring laser gyro is an affordable inertial sensor with the electronics and ring laser gyro packaged into an easy to use compact unit. With its digital I/O the gyro can be integrated into almost any system and used in a variety of commercial, industrial and military applications around the globe. The user only needs to supply an input voltage to receive a digital output signal dependent on rotation.

Each GG1320AN gyro benefits from advanced technology that Honeywell has developed and utilized over the last 40 years. The result is a reliable sensor for all types of inertial sensing.

Performance highlights include start-up time 1 second typical, Bias Stability less than 0.04 degree/hour, and Angular Random Walk less than 0.04 degree/root-hour. The GG1320 Gyro measures 1.77 inches (45 mm) high and is 3.45 inches (87.6 mm) in diameter and weights 1 lb. (450 grams) Its temperature range in an operating mode is -65°F to +185°F (-54°C to 85°C) with an operating altitude of up to +70,000ft (21 km).
