It is an important mission of Geodesy to improve an accuracy of control networks and to establish the geocentric coordinate system via combined satellite and terrestrial network adjustment.
Space geodesy, terrestrial deformation survey and focal mechanics resolution together confirm that the present-time principal compressing stress orientation is NW (NWW) -se (SEE).
空间与地面测量及震源机制解共同证实，东南沿海现时应力场主压应力方位为NW (NWW) - SE (SEE)。
