摘要
介绍了地球坐标参考系统和国际地球参考系及参考框架;阐述了2000国家大地坐标系,指出2000国家大地坐标系可按精度划分为国家级连续运行基准站、GPSA、B级网、天文大地网三个层次。
Introduced in the coordinate reference system and the international terrestrial reference system and frame of reference;described the 2000 national geodetic coordinate system,that 2000 national precision geodetic coordinate system can be divided into national Continuously Operating Reference Station,GPS A,B-class network,astronomy,earth net three levels.
