A method to synchronize the position and orientation of an intelligent guidance device (IGD) 3D Coordinate System with the position and orientation of a 3D measurement device (3DM) 3D Coordinate System, in which the IGD's gravity direction measurement devi...

There is described a method to synchronize the orientation of an IGD 3D Coordinate System and the orientation of a 3DM 3D Coordinate System, in which the IGD's gravity direction measurement device and electronic compass are used explicitly. There is also d...
