Below is the uncorrected machine-read text of this chapter, intended to provide our own search engines and external engines with highly rich, chapter-representative searchable text of each book. Because it is UNCORRECTED material, please consider the following text as a useful but insufficient proxy for the authoritative book pages.

A Statement of Task The National Academies of Sciences, Engineering, and Medicine will convene a committee to prepare a short report which will articulate the views of the U.S. science community on specific Agenda Items at issue at the 2023 World Radiocommunication Conference (WRC) with potential impact on scientific observations, particularly future radio astronomy and Earth remote sensing observations. The committee will: • Identify the 2023 WRC Agenda Items set at the 2019 WRC that are potentially relevant to the scientific use of the radio and microwave spectrum, namely for, but not limited to, radio astronomy and Earth remote sensing; • Assess each of the identified Agenda Items for their potential impact—positive, negative, or none—on radio frequency science applications; • Provide the scientific justification for protecting radio astronomy and Earth remote sensing observations in Agenda Items with potential impact on those observations, where appropriate; • Solicit and consider input from the broad international science community relevant to the committee’s task; and • Establish a position, where needed and within the scope of the identified Agenda Items, to ensure that radio astronomy and Earth remote sensing and other related radio frequency science applications will continue to be able to make needed observations. In preparing its report, the committee will take into account the anticipated future spectrum requirements of the scientific communities and will ensure that the needs of multiple communities are appropriately considered. The report will not consider impacts on the transmission of scientific data. PREPUBLICATION COPY – SUBJECT TO FURTHER EDITORIAL CORRECTION 73

The radio frequency spectrum is a limited resource for which there is an ever-increasing demand from an expansive range of applications - all the way from commercial, such as mobile phones, to scientific, such as hurricane monitoring from space. Since radio waves do not stop at national borders, international regulation is necessary to ensure effective use of the radio spectrum for all parties. Use of the radio spectrum is regulated internationally by the Radio Regulations (RR), an international treaty. The International Telecommunication Union (ITU) has as its mission the facilitation of the efficient and interference-free use of the radio spectrum. Every 2 to 5 years, the ITU convenes a World Radiocommunication Conference (WRC) to review and revise the international RR. Changes to the RR are formulated through proposals to the conference according to Agenda Items, which are agreed on at the previous WRC.

At the request of the National Science Foundation and the National Aeronautics and Space Administration, this report provides guidance to U.S. spectrum managers and policymakers as they prepare for the 2023 WRC to protect the scientific exploration of Earth and the universe using the radio spectrum. This report identifies the 2023 agenda items of relevance to U.S. radio astronomers and Earth remote sensing researchers, along with proposed agenda items for the 2027 WRC.
