Highly Dynamic Object's Four Frequency Laser Gyros Based SINS Measuring System Optimization

A technique has been developed for optimizing the triple uniaxial angular velocity meters configuration for object's permissible angular velocities asymmetric conditions. In general case, the technique leads to the problem of a conditional extremum finding. With its application the use of FFLG with a small operating measurement range can be expanded to the fast one-axis rotation case. A solution to the formulated optimization problem is proposed. The requirements for the FFLG measurements range are reduced by 2.5 times.
