Honeywell's digital ring laser gyro
Gyroscopes or Gyros, are critical rotation sensing elements used in navigation systems (such as: 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 stabilisation systems (i.e. antenna stabilisation), and where accurate pointing and/or targeting is required.
Manufactured by US based Honeywell Aerospace, the company has been involved in gyroscope product development since Elmer Sperry invented the gyrocompass in 1910. Honeywell have products and extensive domain knowledge in gyro technologies including spinning mass mechanical gyros, fibre-optic gyros, Micro-electro-mechanical gyros and ring laser gyros (RLG). Honeywell's GG1320 digital ring laser gyro is the industry standard for precision rotation measurement. Many thousands are in daily use on Land, Sea and Air, commercial and military platforms. 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 digital 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.
The GG1320 digital ring laser gyro, often referred to as a 'gyro laser,' represents the pinnacle of Honeywell Aerospace's advanced navigation technology. Leveraging the principles of laser-based rotation sensing, this cutting-edge device is designed for unparalleled precision and reliability. With its robust construction and compact design, the GG1320 is suitable for a wide range of applications, from commercial aircraft and naval vessels to military vehicles and unmanned aerial systems. This gyro laser technology ensures accurate navigation and stabilization, crucial for both safety and performance in demanding environments. As a result, the GG1320 is a preferred choice for engineers and designers seeking high-performance inertial sensors.
Moreover, the GG1320's gyro laser capabilities extend beyond traditional navigation applications. Its exceptional sensitivity and accuracy make it ideal for platform stabilization systems, where precise pointing and targeting are essential. Whether stabilizing antennas, cameras, or other critical components, the GG1320 ensures optimal performance by minimizing rotational errors. Honeywell's commitment to innovation in gyro laser technology is evident in the GG1320's widespread adoption and trusted performance in various industries. By incorporating this state-of-the-art gyro laser into their systems, manufacturers and operators can achieve enhanced stability, reliability, and accuracy, ultimately leading to improved operational efficiency and safety.
