In over-simplified terms, the ring laser gyro
relies on the accuracy of a number of laser beams impinging on sensors.
Currently, typical IMUs use either Fiber Optic Gyros (FOG) or Ring Laser Gyros
These combine a tri-axial accelerometer, tri-axial gyroscope, tri-axial magnetometer, and a pressure sensor in packages smaller and lighter than ring laser gyros
. These sensors provide primary data for gimbal stabilization and supplementary data for navigation.
"The state-of-the-art Ring Laser Gyros
based high accuracy INS (INS) and Micro Navigation System (MINGS) complementing each other in redundant mode have been incorporated into the missile system in guidance mode," he added.
Besides its unique Zero-lock gyros, it produces spinning mass gyros, ring laser gyros
, fiber-optic gyros, micro electro-mechanical system gyros and hemispheric resonator gyros.

," Air & Space, September 2002.
He has worked on subsurface fractures on mirror substrates, improving position and weapons accuracy, and reducing inertial navigation system drift for ring laser gyros
The division's products and capabilities include fiber-optic and ring laser gyros
, reaction wheel assemblies, position navigation units and fire control and digital battlefield solutions.
For instance, Honeywell's ring laser gyros
developed for BMD were used in commercial aircraft such as Boeing's 737s and 777s, with marked improvements in reliability.
The indigenous Ring Laser Gyros
based high accuracy INS (RINS) and Micro Navigation System (MINGS) complementing each other in redundant mode have been successfully flown in guidance mode for the first time.
The first model available is MGC R3, which includes three Ring Laser Gyros
(RLGs) and three linear accelerometers providing highly accurate readings suitable for demanding applications such as seabed mapping.
