This paper reports a preliminary study on how much the information of GPS precise positioning can help a terrestrial LiDAR to achieve geo-referencing. The experiment conducted in this study is to show the quality of geo-referencing may be achieved by using a commercial hardware and software system without the use of ground control points. The point clouds of multiple stations were collected in a test field for validation. The accuracy of the check points coordinates measured in registered point cloud achieve about 3 centimeters in both E and N direction, and the elevation accuracy is about 6 centimeters. It is good enough for application of point cloud registration to local coordinate system by using GPS data instead of ground control points.
