Measurement device for determining the three-dimensional orientation of a body relative to a reference direction

摘要

The three-dimensional orientation of a body relative to a reference direction is determined with increased accuracy by using a gyro-based azimuth and elevation measurement device which has at least four and preferably eight individual gyros. The individual gyros are positioned such that they react to rotary motions in different directions of space. In a first step all orientation measurement values are determined which are made available by three gyros at a time combined into a so-called triad. In a second step these measured values are combined in evaluated or unevaluated form into an overall measurement value of higher precision.
