3. The space radio telescope of improved precision and rigidity; 30 m in diameter. The weight parameters increase in comparison with version 2 by 15% -17%. The rest of the parameters are the same 4. The "Kolkhida" long, unfoldable (deployable) power structure up to 20 m long 5. The unified transformable crystal (a lattice structure) for construction of large space sites with a pre-stressed carrying system intended for easier assembly in orbit and enhancing both rigidity and geometric precision of the structure parameters. The crystal is helpful in constructing skeletons of any geometrical configuration and sites of virtually any shape and size 6. The pneumo-rigid structure of the space radio telescope up to 50 m in diameter 7. The portable, radio telescope mounted on a truck, for emergency communication with the space-based objects. The aerial reflector diameter is 12 to 15 m. Manufacturing, assembling and maintenance of structure systems Both experimental and launchable prototypes are manufactured by the institute in collaboration with the Tbilisi Industrial Amalgamation for Aircraft Manufacturing (Republic of Georgia). To these ends, the Amalgamation offers the freshest technologies by using parts and units of the structures which are manufactured (there). The assembly procedure is carried out at a dedicated test bench available at the Institute. The test bench is supplied with high precision instruments for assembly control as well as with a sensitive system of weight annulment (neutral buoyancy) of the structure as a whole as well as its parts. A highly skilled team of the mechanical engineering technology, aircraft engineering technology, materials programming and metrology experts is involved in the manufacturing process. Full-scale structure testing Testing is the most important part of space unit construction and requires tracking down of the complex technological problems through development of the test benches with imitation weightlessness and other space parameters. It is also expensive and requires large material resource expenditures, highly skilled manpower and energy resources . The Institute has designed and implemented a unique testing complex for the large space structures and radio electronic systems The test complex consists of: • 40 m diameter structures precision assembly jig with high precision mechanical weightless and testing systems, • 1200 m floor area with controllable surface,
