Science Service Allocations

This chapter lists radio spectrum allocations for both passive and active science services described in Chapters 1, 2, and 3. For spectrum allocation purposes, the Radio Regulations of the International Telecommunication Union (ITU) divide the world into three regions, as shown in Figure 5.1. The United States (U.S.) is in Region 2. As of June 2015, the spectrum allocations are established only for frequencies below 275 GHz. Nonetheless, while no formal allocations are established above 275 GHz, the ITU Radio Regulation 5.565 urges administrations to take all practicable steps to protect passive services from harmful interference in the frequency range of 275-1000 GHz and states that 1000-3000 GHz may be used by both passive and active services.1

Frequency allocations and footnotes relevant to the science services in Radio Astronomy, Earth Exploration, Space Research and Operation, and Meteorological Aids and Satellite are listed in Table 5.1. The allocations presented in this chapter are based upon the Table of Frequency Allocations published by the U.S. Federal Communications Commission (FCC) on May 15, 2015, and codified at Section 2.106 of the Commission’s Rules. Table 5.1 consists of the International Table of Frequency Allocations (“International Table”) and the U.S. Table of Frequency Allocations (“United States Table”). The International Table is subdivided into allocations for the three regions (Columns 1, 2, and 3). The U.S. Table is subdivided into the allocations for federal government services (Column 4) established by the National Telecommunications and Information Administration (NTIA) and non-federal government services (Column 5) established by the FCC. Some of the pertinent rules or rule parts2 for non-federal allocated services established by the FCC are provided in Column 6. In addition, Column 7 lists key areas of study enabled by the scientific services, along with corresponding section numbers from Chapters 1, 2, and 3 where these services are described in detail.

_____________

1 The full text of ITU Radio Regulation 5.565 is provided at the end of Table 5.1.

2 A selected list of these rules and regulations that are particularly relevant to Radio Astronomy Service and Earth Exploration Satellite Service are given in Appendix G. The full rules and regulations are codified in Title 47 of the Code of Federal Regulations (CFR). They are initially published in the Federal Register. Links to the CFR are maintained by the FCC at https://www.fcc.gov/encyclopedia/rules-regulations-title-47.

FIGURE 5.1 The regions in Article 5 of the Radio Regulations of the International Telecommunication Union. The shaded part represents the Tropical Zone. SOURCE: National Telecommunications and Information Administration, Manual of Regulations and Procedures for Federal Radio Frequency Management (Redbook), May 2013 edition, revised May 2014. See http://www.itu.int/ITU-R/ for more information.

Each row in Table 5.1 consists of the frequency range covered and the services allocated in that range. The table lists frequency ranges that are relevant to the science services and includes all other services that are allocated in those ranges. The services marked in all capital letters (such as “EARTH EXPLORATION SATELLITE”) indicate a primary allocation, where entities properly authorized to operate in that service are entitled to protection from harmful interference from any other services in that frequency range. The services with the first letter capitalized (such as “Radio astronomy”) indicate that the allocation is on a secondary basis. The ITU rules require that “stations of secondary services: i) shall not cause harmful interference to stations of a primary service to which frequencies are already assigned or may be assigned at a later date; ii) cannot claim protection from harmful interference from stations of a primary service to which frequencies are already assigned or may be assigned at a later date; and iii) can claim protection, however, from harmful interference from stations of a same or other secondary service(s) to which frequencies may be assigned at a later date.” Along with the primary and secondary services, each row has numbers such as “5.340” in the International Table, indicating footnotes to the allocation table. If the footnote appears directly next to the service, then it applies only to that service. If it appears at the bottom of the row, then it applies to all the services in the frequency range. Footnotes are important and may place significant restrictions on specific services or provide for additional allocations in the frequency range. For example, in the International Table, footnote 5.340 provides exclusive protection for the passive services in several frequency ranges. In the U.S. Table, the footnotes are marked with prefixes such as “US,” “NG,” or “G,” indicating applicability of the footnotes to both federal and non-federal operations, only to non-federal operations, or only to federal operations, respectively. All the footnotes relevant to the Radio Astronomy Service (RAS) and the Earth Exploration

Satellite Service (EESS) described in Chapters 2 and 3 are set in boldface. The frequency allocations that contain footnotes relevant to science services are explicitly marked as “Regulations relevant to science services” in Column 7. Full texts of all the footnotes used in the allocations table are reprinted from the FCC Table of Frequency Allocations and provided at the end of Table 5.1.

Any radio astronomy or Earth remote sensing station observing in a band in which RAS or EESS is allocated is urged to register its operations so that the regulator is aware of its presence and can provide interference protection. For RAS sites, registration is typically done through the National Science Foundation’s Electromagnetic Spectrum Management office; for EESS sites, registration is typically done through the NASA Space Communications and Navigation Directorate’s Spectrum Management office or the National Oceanic and Atmospheric Administration’s Radio Frequency Management Division.

Because regulations, allocations, and footnotes can change, the reader is advised to consult NTIA’s Manual of Regulations and Procedures for Federal Radio Frequency Management (Redbook) or the FCC’s Online Table of Frequency Allocations, the Radio Regulations, and the ITU Radiocommunication Sector (ITU-R) recommendations for the latest information. The Redbook can be found at http://www.ntia.doc.gov/osmhome/redbook/redbook.html, the FCC’s document can be found at http://www.fcc.gov/oet/spectrum/table/fcctable.pdf, and the ITU-R recommendations are at http://www.itu.int/opb/.

US565 The frequency band 275-1000 GHz may be used by administrations for experimentation with, and development of, various active and passive services. In this band a need has been identified for the following spectral line measurements for passive services:
 

— radio astronomy service: 275-323 GHz, 327-371 GHz, 388-424 GHz, 426-442 GHz, 453-510 GHz, 623-711 GHz, 795-909 GHz and 926-945 GHz;

 

— Earth exploration-satellite service (passive) and space research service (passive): 275-277 GHz, 294-306 GHz, 316-334 GHz, 342-349 GHz, 363-365 GHz, 371-389 GHz, 416-434 GHz, 442-444 GHz, 496-506 GHz, 546-568 GHz, 624-629 GHz, 634-654 GHz, 659-661 GHz, 684-692 GHz, 730-732 GHz, 851-853 GHz and 951-956 GHz.

 

Future research in this largely unexplored spectral region may yield additional spectral lines and continuum bands of interest to the passive services. Administrations are urged to take all practicable steps to protect these passive services from harmful interference until the date when the allocation Table is established in the above-mentioned frequency band.

The electromagnetic spectrum is a vital part of our environment. Measures of radio frequency emissions from natural phenomena enable both practical applications, such as weather predictions and studies of the changing of Earth's climate here at home, and reveal the physical properties of cosmic sources. The spectrum is therefore a resource to be used wisely now and to be protected for future generations.

Handbook of Frequency Allocations and Spectrum Protection for Scientific Uses: Second Edition sets forth the principles for the allocation and protection of spectral bands for services using the radio spectrum for scientific research. This report describes the radio frequency bands used by scientific services and includes relevant regulatory information and discussion of scientific use of frequency bands. This reference will guide spectrum managers and spectrum regulatory bodies on science issues and serve as a resource to scientists and other spectrum users.
