Effects of transient behavior during Minuteman IMU calibration
Abstract
Some results of studies of transient phenomena in a gyrocompass and alignment assembly, which is the primary azimuth and level reference for the inertial measuring unit of the Minuteman navigation system, were described. The assembly is examined under the thermal change and repositioning environment occurring during a system calibration mode of operation. The response and characterization of the system to transient environments are derived from the summation of subcomponent responses by applying the principle of superposition. The response is expressed in terms of its time constants. These time constants are used to correlate the system behavior with subcomponent behavior which was characterized under a simulated-system environment. Further examination of experimental and analytical modelling illustrates how physical interpretation of time constants is possible.
