GG1320AN Digital Ring Laser Gyroscope
Overview
Gyroscopes are critical rotation sensing elements used in navigation systems (inertial navigation systems (INS), attitude and heading reference systems (AHRS) or inertial measurement units (IMUs) for manned and unmanned aircraft, spacecraft, marine vehicles and surface vehicles.
In addition, gyroscopes are important elements in platform stabilization systems (i.e. antenna stabilization) and where accurate pointing and/or targeting is required.
Today, Honeywell's GG1320 digital ring laser gyro (RLG) is the industry standard for precision rotation measurement. It is an affordable high performance inertial sensor with the electronics, power supply and sense element packaged into an easy-to-use compact unit. The user supplies an input voltage and under rotation, the GG1320 provides a compensated rotation output.
The principle of operation of a RLG is two 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. Honeywell's GG1320 RLG has demonstrated capability of measuring an arc-second of rotation.
Honeywell gyro technologies include:
Honeywell offers a low, medium, and high performance grade of GG1320AN2X available for purchase. See the ‘Product Brochure Title’ for further details. Further refinement of specific performance variables may be available by request.
