Designing of the Motion Meter Unit for Systems Calculating the Position of an Object in Space

摘要

The method of an error model building for accelerometer strapdown inertial navigation system is considered. The model is performed as a system for calculating the position of an object in space to determine the boundaries of its effective use. The requirements to the accuracy of the accelerometer system calibration are formulated. The area of effective application of accelerometric angular velocity measurements is constructed. Sensing error effect in the block on accuracy of measurements is considered. The requirements to an admissible level of an accelerometers measurements error according to the permissible error of the obtained angular velocity estimation are received.
