3 The U.S. National Academy of Sciences (NAS) was established on March by Act of Congress, signed into law by President Abraham Lincoln in the midst of the United States Civil War. The NAS was established to "investigate, examine, experiment, and report upon any subject of science or art" whenever called upon to do so by any department of the government. 3

5 Responsibilities of The Committee on Radio Frequencies (CORF) Coordinates the views of U.S. radio astronomers and Earth remote sensing researchers to represent their interests Manages radio-frequency requirements for scientific use and interference protection by filing comments in public proceedings of the Federal Communications Commission (FCC) and the National Telecommunications and Information Association (NTIA) Conducts report-writing and outreach activities Supported by NASA and NSF. Established in 1961.

10 The CORF Handbook Handbook on Frequency Allocations and Spectrum Protections for Scientific Uses (2007) A resource for scientists, engineers, and spectrum managers. Detailed information including a description of regulatory bodies and issues, a discussion of the relevant scientific background, a list of science spectrum allocations in the United States, and an analysis of spectrum protection issues for RAS and EESS. 10

11 Spectrum Management for Science in the 21 st Century (2009) Addresses the tension between the active commercial services' demand for greater spectrum use and the passive users' need for quiet spectrum Recommendations provide a pathway for putting in place the regulatory mechanisms and associated supporting research activities necessary to meet the demands of both users 11

12 CORF Views on WRC-2015 (2013) CORF provided input to the U.S.Government on Agenda Items at issue at the WRC-15 Comments on agenda items with potential impact to RAS and EESS services 12

13 A Survey of the Active Scientific Use of the Radio Spectrum A new study committee led by Fawwaz Ulaby (U. Michigan) is conducting a study of the active scientific use of the spectrum similar to Spectrum Management for Science in the 21st Century. Supported by NASA. To be completed released by the end of the year. 13

14 Current & Future CORF Activities Meets in-person twice per year. Periodic teleconferences. Update CORF Handbook. Complete Active Sensing Study. Begin Views on WRC

15 International CORF Activities Symposium in August 2009 in Santiago, Chile. Symposium in Puebla, Mexico, in 2015? Invites spectrum managers from around the world to provide updates at meetings. CORF consultant attends WP7D meetings and reports back. 15
