Is Widespread Civil Use of GPS in Jeopardy? ------------------------------------------- According to the 8 and 15 January 1990 issues of Aviation Week & Space Technology, there is concern that the U.S. Department of Defense might be considering a change in its policy regarding the use of the Navstar Global Positioning System by the civilian community. The magazine refers to a letter dated 14 December to Defense Secretary Richard B. Cheney and Transportation Department Secretary Samual K. Skinner signed by the heads of five U.S. airspace user organizations and three former Federal Aviation Administration officials. The letter states that "in recent months, we have heard renewed concerns in some organizations within [the Defense Department]. ... A number of old issues which we had thought had been previously laid to rest apparently are being raised again, including the appropriateness of making GPS available to the civil community, and restated concerns about technology transfer problems." It appears that some Pentagon "nervous Nellies" (in AW&ST's words) are not content with restricting the real-time positioning capability of most civil users but want the U.S. to withdraw GPS completely from civil use. Such a move would renege on Reagan's offer of GPS to the aviation community which followed the shoot-down of a Korean Airlines 747 in late 1983 and the 1988 U.S./U.S.S.R. bilateral treaty on cooperation on transportation science and technology, including navigation satellites. Cheney and Skinner are to meet early this month to resolve the issue. In related developments, the FAA has funded a program at the Massachusetts Institute of Technology's Lincoln Laboratory to monitor the signal characteristics of the U.S.S.R.'s Glonass satellites and to develop a dual GPS/Glonass receiver for civil use. The receiver could make use of Receiver Autonomous Integrity Monitoring to determine if any of the received GPS or Glonass signals are out of tolerance. RAIM is essentially a majority voting technique which computes the position of the receiver using different combinations of satellites. Flight tests of the future receiver are scheduled for 1992.

February 1, 1990 RELEASE: 90-18 NASA SELECTS EIGHT RESEARCH SATELLITE COMMUNICATIONS PROPOSALS NASA has selected eight research proposals to help maintain U.S. preeminence in satellite communications. Still under contract negotiations, the proposals will result in contract awards by April 1990. The proposals were submitted under the Satellite Communications Applications Research Program (SCAR), which has an annual budget of $2 million. SCAR was established to support promising satellite-based communications technology systems. The program will aid applied research, innovative services and, ultimately, accelerate transferal of the results of this research to the user community. The program's goal is to define and develop space communications technology that can be used by the industry to open up new communications services. These proposals were selected for their potential for improvements in technology, materials, processes, methods, devices, or techniques, as well as to advance the state-of-the- art of satellite communications. Selected by an extensive peer review process, the eight proposals were chosen from a total of 85 submitted in response to a NASA research announcement (NRA-89-OSSA-14). The selected proposals and their submitting organizations follow: o "1 Watt CW 2-D Steerable Coherent Monolithic Semiconductor Master Oscillator Power Amplifier," Spectra Diode Laboratories, Inc., San Jose, Calif.; o "Efficient, High Power, Solid State Amplifier for EHF Communications," Rockwell International, Anaheim, Calif.; o "Superconducting MMW Phased Array," Ball Aerospace Systems Group, Broomfield, Colo.; o "Commercialization of Optic Intersatellite Links," COMSAT Laboratories, Clarksburg, Md.; o "On-Board B-ISDN Fast Packet Switching Architectures," COMSAT Laboratories, Clarksburg, Md.; o "Advanced Satellite Designs and Experiments for ISDN Service," Contel Federal Systems, Chantilly, Va.; National Telecommunications and Information Administration, Institute for Telecommunications Science of the U.S. Department of Commerce, Boulder, Colo.; and the University of Colorado Interdisciplinary Telecommunications Program, Boulder; o "Flexible-Rate HDTV Codec," COMSAT Laboratories, Clarksburg, Md.; o "Neural Network-based Decoders of Convolutionally Encoded Data for Satellite Communication," University of California, San Diego. SCAR intends to help maintain U.S. technological and economic preeminence in satellite communications by enabling new and innovative services for private and public sector needs. This program is managed by the Communications and Information Systems Division of the Office of Space Science and Applications, NASA Headquarters, Washington, D.C. ------------------------------ Date: 2 Feb 90 02:00:13 GMT From: zaphod.mps.ohio-state.edu!brutus.cs.uiuc.edu!ux1.cso.uiuc.edu!tank!iitmax!demodmb@tut.cis.ohio-state.edu (Dean M. Bleess) Subject: STS Mission Order (Shuttle) The reason for the mission numbering anomalys (ies? -whatever) is because (I quote from the mission manifest) 'In the mission integration process, efficiency and integrity are enhanced if flight numbers are maintained after assignment at 19 months before launch. With manifest changes, numerical sequence of early flights is not maintained.' This means if something comes up and flight schedules have to be juggled to meet launch windows or other flight requirements, it is easier for NASA to not just move the flight but move it's mission designation also. It does help cut down on confusion even if it doesn't have the nice flow of the previous programs numbering systems. -DMB@IIT ------------------------------ Date: 2 Feb 90 00:58:48 GMT From: trident.arc.nasa.gov!yee@ames.arc.nasa.gov (Peter E. Yee) Subject: New directors named for international and industry relations (Forwarded) Debra J. Rahn February 1, 1990 Headquarters, Washington, D.C. RELEASE: 90-20 NEW DIRECTORS NAMED FOR INTERNATIONAL AND INDUSTRY RELATIONS NASA announced today the appointments of Peter G. Smith to the position of Director, International Relations Division, and David L. Stottlemyer to the position of Director, Industry Relations Division. Smith's appointment becomes effective Feb. 5, 1990. He will replace Richard J.H. Barnes who is retiring after 29 years of NASA service. Stottlemyer was appointed to his postion Jan. 10, 1990, and replaces Carl F. Emde who is serving as special assistant to the Associate Administrator for External Relations. Smith will be responsible for planning and directing NASA's international relations. Smith is currently Deputy Director of International Relations, a position he assumed in 1987. Previously, he was Chief of the International Program Policy Office in the International Affairs Division, which he joined in 1979. Before that, he was a foreign service officer and China specialist with the Department of State for 14 years, serving in Hong Kong, Seoul and Taipei. Smith received a BS degree from Wesleyan University, Middletown, Conn., and did graduate work in Chinese studies at the University of Michigan. He also trained as an interpreter at the State Department's Chinese language school in Taichung, Taiwan. Stottlemyer received a BA degree from Miami University, Ohio, and a master's degree in public and international affairs from the University of Pittsburgh. He also did doctoral work at the same university. In 1964, Stottlemyer joined the federal government, initially with the Bureau of the Budget's International Programs Division. He entered the U.S. Foreign Service in 1971 and was assigned to the U.S. Mission to the United Nations in New York. Subsequently, he held a number of positions with the Department of State in Washington and in early 1981, joined the staff of then Vice-President George Bush. Stottlemyer returned to New York and the United Nations in 1984, serving as Director of Management and subsequently, as Director, Office of the Under- Secretary-General for Finance and Administration. He retired from the Foreign Service and the United Nations in 1987. ------------------------------ End of SPACE Digest V10 #464 *******************
