Determining Permissible Levels of Frequency Characteristics of Measuring Channels in a Strapdown Inertial Navigation System

The influence of linear and vibration loads on the typical errors of a strapdown inertial navigation system under conditions of an autonomous (purely inertial) flight configuration is considered. The list of the instrumental and methodological components of the error of the strapdown inertial navigation system under consideration, which have a decisive impact on the tolerance of the amplitude-phase frequency characteristics of the measuring channels, has been mentioned. The method for determining the permissible levels of the frequency characteristics of the measuring channels is described. The numerical simulation results are presented.
