Zhou Dong-wei · Journal of Southwest Jiaotong University · 2007
A fast growth algorithm for GPS(global positioning system) network construction was developed based on the characteristics of maximized dihedral angle of SDTIN(spherical Delaunay triangulated irregular network).The coordinates,as test data,of GPS sites of ITRF(international terrain reference frame) were utilized to construct a global SDTIN in order to prove the reliability of the algorithm.In addition,the directly searching algorithm for SDTIN was compared with the fast growth algorithm.The comparison result shows that the fast growth algorithm is effective.
