Considering the characteristics of the structure design of satellite deployable antennas made up of cable-net with truss, the system architecture and basic functions of a comprehensive design oriented computer software program are ex-pounded systematically in this par. The overall unit digital modeling and data base module of this kind of antenna ( As-tromesh, Radial rib and Truss) have been developed. The hiberarchy of overall unit design is established and the method of abstracting and categorizing are proposed to solve the difficulty of the antenna CAD/CAE integration modeling. The devel-oped program is composed of parameter modeling, data base, cable net form funding, dynamic optimization with both states of deployed and stowed ones, thermo analysis, multi-flexible body dynamic analysis and deployable control, reliability anal-ysis, electronic performance analysis, measuring and the cable-net-reflector precision adjustment. This manuscript will mainly introduce three part of the program, such as the overall skeleton, parameter modeling and data base. This program has been applied in some practical deployable satellite antenna design with good results, which show the ability of aided in-novation design, decreasing research cost and increasing both performances of electronic and structural aspects.
