Accurate measurement of spatial angles, trajectories, contours etc. - uses sequential angle and/or velocity and/or position measuring w.r.t. unknown, but identical starting states

摘要

The accurate measurement of spatial angles, trajectories, contours, motion processes and gravity anomalies with gyroscopes and inertial systems involves sequential measurement of angles and/or speeds and/or positions w.r.t. unknown, but identical, initial conditions. The differences in the sequential measurements are formed as system error differences in a computer, which provides models for relationships between system error differences and sensor errors at the start and end of the measurements and performs optimal approximation. Two system error time functions are derived as the basis for a common time function, which is used for correcting the measurements. USE/ADVANTAGE - For many types of constructional work and civil engineering, with improved operation and measuring precision. Aircraft and motor vehicle research.
