BACKGROUND

The Moscow Institute of Physics and Technology is a teaching and research institute with about 4000 students enrolled in the six-year program and 1000 post graduate students. There are nine departments or colleges within the institute. Space communications-related work is performed in the departments of Radio Technical Cybernetics, Space Investigations, Physics and Quantum Electronics, and Computer Sciences and Applied Mathematics. Technical discussions dealt not with the work of the institute, but mostly with plans for future satellite systems.

RESEARCH AND DEVELOPMENT ACTIVITIES

In papers presented in Budapest and Geneva, Academician Gulyaev described three proposed satellite systems that would be launched by PROTON launchers (see references in the report chapters). The proposed EXPRESS system is a modernization of the GORIZONT satellites. EXPRESS M would be used for television. MAYAK is a proposed modernization of the MOLNYIA satellites.

Another proposed system would use the 30 m deployable antenna designed by the industrial firm KOMETA on an 18 metric ton geostationary communications satellite. The mass used would be 9 metric tons for telecommunications and 9 metric tons for maintenance and service. The satellite would have 20 kW of electrical power. In 1990 this system was proposed for 64 kbps trunking applications that would link 50 million persons together. Terrestrial infrastructure to support this application will not likely be available until about 2005.

To build up the telephone switching systems to support such a large telecommunications satellite, advanced molecular beam epitaxial technology is critical. Efforts within Russia are producing GaAs and InPh devices. HEMT devices with up to 100 quantum wells per structure are being built.

Academician Gulyaev foresees a role for satellites in trunking applications in Russia, even with fiber optic network development, because of the geography and population distribution of Russia.

SUMMARY

The discussion with academician Gulyaev principally covered planned systems of satellites. Satellite systems are proposed for modernizing the GORIZONT and MOLNYIA systems. A large satellite for trunking applications needs terrestrial infrastructure development in order for the market to develop. Technology import restrictions have led to internal technology developments in the areas of molecular beam epitaxial technology and fiber optics cable.
