ABSTRACT

In this paper, the author analyzes the possibility of obtaining the orientation of geologic planes by using GPS tools. Theoretical background for such procedures is represented by an analytical model of finding the attitude by using three noncollinear points. During the experimental stage orientation measurements on synthetic planes were carried out by using GPS tools and geological compass. The output data obtained by GPS and compass was analyzed and compared by using stereographic projection. The measurement uncertainty connected with floating-point arithmetic was discussed, inaccuracies with locating the points in three-dimensional space were also considered. In this context, the author introduces the problem of the smallest value of area generated by three noncollinear points that can be considered in terms of a reliable measurement. The author points out that in order to extend the set of existing and potential applications of this analytical model, there is a need of introducing some topological notions.
