Design of an optimal position testing method for dynamically tuned gyro

Positions test method design needs to strive to minimize the errors and maximize accuracy of dynamically tuned gyro's output. We applied quadratic surface composite design methodology to D-optimal positioning testing method and proposed a novel optimal 8-position testing method. Experimental result shows that the accuracy of estimating acceleration-insensitive drift rate and acceleration-sensitive drift rate coefficients using this eight position testing method is 4-8 times better than that of IEEE std 813-1988.
