| Abstract: | According to the characters of urban and enginering control network,this paper analyses all sorts of determined ellipsoids applied to the special control network, shows the numerical results compared the positioning relation ship between these ellipsoidal surfaces and the refference surface. We have the conclusion that the fourth ellipsoidal surface is better one than anothers. |
