A New Measurement Model Of Gps And Inclinometer In Coordinate Transform

According to the basic principle of GPS and the characteristics of inclinometer in measuring angle, this paper proposed a new method based on the combination of double GPS with inclinometer to measure the rotation parameters of coordinate transformation. Firstly, model coordinate system is established which associated with the GPS and inclinometer, then the three rotation angles between model coordinates system and Station Local Cartesian Coordinate System(SLCCS) can be get by biaxial inclinometer output and the projection of double GPS coordinates in the SLCCS. Experiment shows that, the method is simple, fast, effective, and accuracy fully meets the engineering measurement needs. Compared with the common points conversion method, this method has great improvement in the aspects of accuracy, efficiency etc..
