CGCS2000与PZ-90.02坐标系的对比
Comparisons and Analysis with CGCS 2000 and PZ-90.02
摘要
Abstract
According to the fundamental constants of the ellipsoid adopted by CGCS 2000 and PZ-90.02,the main geometrical and physical parameters of the ellipsoids of CGCS 2000 and PZ-90.02 are derived and compared.The difference of geodetic coordinates,normal gravity and normal gravity-vertical gradient on the same point between these two ellipsoids are analyzed.Studies show that the difference of geodetic coordinates on the same point between CGCS 2000 ellipsoid and PZ-90.02 ellipsoid changes along with latitude and longitude,the absolute value of the maximum difference of longitude,latitude and height between CGCS 2000 and PZ-90.02 are 0.147 743 00",0.011603 10" and 0.772 345m respectively,and the absolute value of the difference between normal gravity and normal gravity-vertical gradient on CGCS 2000 ellipsoid and that on PZ-90.02 are about 3.067 18× 10-6m/s2 and 1.461 73× 10-3E respectively.关键词
