Executive summary ㅇ Introduction ㅇ Principal Observations and Conclusions 1. The panel observed that many European and Asian governments are maintaining or increasing their funding of commercial communications satellite R&D. The U.S. government, on the other hand, does not appear to be supporting such R&D at the level that is necessary to continue the leading U.S. market share position in this growing business. The current level of NASA R&D funding in this area is barely adequate to meet the competitive challenge posed by other nations. There is a critical and growing need for new technology in this technology-intensive industry. Continued funding for the long-term R&D programs at NASA, DOD, and NSF is crucial to the continued success of the U.S. commercial satellite communications industry in the next century. 2. The United States is the leader in the manufacture, insertion of new technology, development and finance of new commercial communications satellites, but foreign competition is increasing and this point needs to be addressed for the United States to maintain this lead. Further, the United States has lost its preeminence in the satellite launch service area and this must be viewed with concern. In addition, there is a critical need for lower cost and more reliable launch vehicles. 3. Commercial communications satellite services are rapidly becoming a large and global business, increasing from $11 billion in 1992, to $20 billion in 1996 to our projected figure of $75 billion in 2005 4. New technology is being inserted into commercial satellite communications at an increasingly rapid pace. 5. Aerospace communications companies worldwide are expanding from their traditional role as equipment vendors into the end service provider business. 6. commercial communications satellites are increasingly being used to provide services directly to the end-consumers, creating a potentially large terminal industry. 7. Satellite manufacturing is attaining maturity and is following manufacturing procedures that are similar to those used by the automobile industry. 8. The increased global interest in the use of satellite based communications systems has created a demand for spectrum and orbital slots that exceeds availability. In addition, there is competition for much of this spectrum from terrestrial wireless systems. 9. Future development of commercial satellite communications appears to hinge on key regulatory, trade, spectrum, and inter-operability and standards issues as much as new technology development --- and here government leadership and initiative will be the key. 10. Opportunities for International cooperation can facilitate the global development of new satellite technologies, systems and standards. 11 There is considerable R&D work being done around the world on the understanding and development of protocols and standards to ensure the seamless interoperability of satellite and terrestrial communications transport facilities. ㅇ Background ㅇ Scope - Technology focus - Market Focus - Regulatory and Legislative Focus - Global Focus - Limitations - Perspective on the industry ㅇ Technology trends ㅇ Concerns - R&D: - Protocols and Standards: - Trained Engineer Shortage: - Spectrum: - Launch Services and Facilities:
