GPS precision positioning in a regional net using pseudo-nonfiducial method
Abstract
The pseudo-nonfiducial positioning method is applied to a regional GPS net, and compared with conventional fiducial method. The conclusions are that there are respective characteristics and application area for both methods. The pseudo-nonfiducial method can avoid the problem of net shape twisting which is difficult to be overcome in the fiducial method, and the choice and changing of the transformation fiducial site as well as increasing or decreasing the number of transformation fiducial site are all very convenient and simple. It is valuable to spread the pseudo-nonfiducial method.
