This paper introduces the method of route survey using RTK GPS and discusses the matter of precision of the beeline.

Turned the distance between the space point and the beeline and the distance between the two beelines which are not in the same plane into the maximum of the distance between the point and the plane pencil.

This beeline displacement sensor is based on the principle of electromagnetism influ- ence,using film inductance coil twisted on the cylinder to get a high frequency electromagnetic field,and it has two coils with the same parameter.

A general synthesis model of mixed-point straight-line linkage in the general condition was established,and some key parameters in the equations were solved.

Based on the synthesis theory concerning the mixed point straight-line four-bar linkage in the special condition, a research method with the circle center and circle point as parameters is proposed.

Based on the double-faced projection drawing of a space plane,this paper analyzes the relative position of the space plane to an observer,compares the coordinates of the two end points of a straightline segment and puts forward a method for visibility discrimination in the line-plane and plane-plane intersection problems.
