Measurement device for determining the three-dimensional orientation of a body relative to a reference direction
First Claim
1. Measurement device for determining the three-dimensional orientation of a body relative to a reference direction, with a housing for resting on the surface or one edge of a body to be measured, and with a plurality of gyro systems for determining the proportional rotary motion around one axis of symmetry at a time assigned to them, characterized in that at least four, individual gyros are present within the housing and are oriented to different three-dimensional directions, and all combinations of three individual gyros at a time which can be combined into a so-called gyro triad yielding one first measurement result at a time which identifies the three-dimensional angular orientation of the measurement device or a body which has made contact with it so that a plurality of initial measurement results is made available and from the plurality of initial measurement results an overall measurement result is determined it.

Abstract
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.
