The characteristics of a ring laser gyro with regard to the accuracy are presented. The suitability of the laser gyro for static and dynamic angle measurements on a standard production Honeywell GG 1342 type with dither bias compensation was studied. The angle reference used for the static measurements was a 12-sided polygonal mirror in conjunction with a photoelectric autocollimation telescope. For the dynamic measurements, the inductosyn angle transducer of a gyro test table calibrated with the above-mentioned device was used. In the process it emerged that the laser gyro can also be used for fine calibration of a precise angle transducer. The influence of the gyro's scale factor and drift variations on the angle measurement deviations was investigated. Quantization noise was reduced in the data processing on the basis of fast sampling. Drift measurements included tests lasting one week. These results are also relevant for precise navigation and stabilization purposes. It transpired that random walk drift was the limiting factor for accuracy of nonrepeatable angle measurements.
