Control characteristics of space antennas consisted of cable networks are investigated. Two control systems are employed to gain a high precision antenna surface. In the one system, the surface is adjusted by controlling tensions of tie cables. And in the other system, the surface is adjusted by controlling tensions of boundary cables. These systems are compared through some numerical simulations, which are carried out using force density method. It is shown that low order deformation, such as thermal deformation, can be corrected by the both systems if there is no measurement error of the surface. And it is clarified that the surface errors are grown through the controlling tensions of the tie cables if there are measurement errors.
