A NONLINEAR CONVERSION MODEL FORM ITRFYY TO CGCS2000

A NONLINEAR CONVERSION MODEL FORM ITRFYY TO CGCS2000

At present, ITRS series reference frameworks are widely used in the world. The results of GNSS are mostly based on the ITRF framework. Transform from ITRF to CGCS2000 is not easy, which restricts the promotion and use of CGCS2000. The conversion relationship between CGCS2000 and ITRF framework has i...
