Abstract
A procedure of assessing the main characteristics of angular velocity inertial meters of middle and low accuracy classes, including measuring channel noise terms is proposed. The procedure is based on the processing of the meter output information by means of the Kalman discrete filter and the Allan variance method. The characteristics to be estimated are: scale coefficient errors and zero signal shifts, as well as series of standard noise terms. Estimates of the method error level for the procedure under consideration are given on the basis of mathematical simulation of the measurement information and its correction with different estimated errors. An example of approbation of the technique is processing the results of tests conducted for two inertial meters based on different operating principles. One of them is the ADIS16405 device developed by Analog Devices (USA) on the basis of three micromechanical gyroscopes of low- accuracy class and the other is the ВГ910-МК470 device designed by Fizoptika, CJSC (Arzamas city) which consists of one fiber-optic gyroscope of the middle -accuracy class.
