Application of penalized least squares method in geodetic coordinate system transformation

LIU Yi1,YUE Jian-ping1,LU Yin-hong1,XI Guan-fan2(1.School of Earth Science and Engineering,Hehai University,Nanjing 210098,China;2.Nanjing Institute of Surveying and Mapping Co.,Ltd,Nanjing 210005,China)  
There is still a big residual in coordinate conversion between reference and geocentric.By analyzing the model errors,it presents a penalized least squares model that regards the model error as a semi-non-parametric signal.Through calculating and analyzing the measured data,this model can effectively eliminate the residual model error,to achieve high-precision coordinate transformation.
