10 GHz (10,000,000,000 Hz)

Footnotes

  • 5.474A   The use of the frequency bands 9 200-9 300 MHz and 9 900-10 400 MHz by the Earth exploration-satellite service (active) is limited to systems requiring necessary bandwidth greater than 600 MHz that cannot be fully accommodated within the frequency band 9 300-9 900 MHz. Such use is subject to agreement to be obtained under No. 9.21 from Algeria, Saudi Arabia, Bahrain, Egypt, Indonesia, Iran (Islamic Republic of), Lebanon and Tunisia. An administration that has not replied under No. 9.52 is considered as not having agreed to the coordination request. In this case, the notifying administration of the satellite system operating in the Earth exploration-satellite service (active) may request the assistance of the Bureau under Sub-Section IID of Article 9. (WRC 15)

  • 5.474B   Stations operating in the Earth exploration-satellite (active) service shall comply with Recommendation ITU R RS.2066 0. (WRC 15)

  • 5.474C   Stations operating in the Earth exploration-satellite (active) service shall comply with Recommendation ITU R RS.2065 0. (WRC 15)

  • 5.474D   Stations in the Earth exploration-satellite service (active) shall not cause harmful interference to, or claim protection from, stations of the maritime radionavigation and radiolocation services in the frequency band 9 200 9 300 MHz, the radionavigation and radiolocation services in the frequency band 9 900-10 000 MHz and the radiolocation service in the frequency band 10.0-10.4 GHz. (WRC 15)

  • 5.479   The band 9 975-10 025 MHz is also allocated to the meteorological-satellite service on a secondary basis for use by weather radars.

  • 5.480   Additional allocation: in Argentina, Brazil, Chile, Cuba, El Salvador, Ecuador, Guatemala, Honduras, Paraguay, the overseas countries and territories within the Kingdom of the Netherlands in Region 2, Peru and Uruguay, the frequency band 10 10.45 GHz is also allocated to the fixed and mobile services on a primary basis. In Colombia, Costa Rica, Mexico and Venezuela, the frequency band 10 10.45 GHz is also allocated to the fixed service on a primary basis. (WRC 19)

  • G32   Except for weather radars on meteorological satellites in the band 9.975-10.025 GHz and for Federal survey operations (see footnote US108), Federal radiolocation in the band 10-10.5 GHz is limited to the military services.

  • NG50  In the band 10-10.5 GHz, non-Federal stations in the radiolocation service shall not cause harmful interference to the amateur service; and in the sub-band 10.45-10.5 GHz, these stations shall not cause harmful interference to the amateur-satellite service.

  • US108   In the band 10-10.5 GHz, survey operations, using transmitters with a peak power not to exceed five watts into the antenna, may be authorized for Federal and non-Federal use on a secondary basis to other Federal radiolocation operations.

  • US128   In the band 10-10.5 GHz, pulsed emissions are prohibited, except for weather radars on board meteorological satellites in the sub-band 10-10.025 GHz. The amateur service, the amateur-satellite service, and the non-Federal radiolocation service, which shall not cause harmful interference to the Federal radiolocation service, are the only non-Federal services permitted in this band. The non-Federal radiolocation service is limited to survey operations as specified in footnote US108.

AN/APS-137(V) Search Radar

Current Use
9.3–10.1 GHz AN/APS-137(V) search radar
According to Forecast International, "the APS-137(V) was designed as a search radar to detect and track surface vessels, submarine periscopes, and snorkels in high sea states." The radar was used in the Navy's P3 Orion surveillance aircraft for various purposes, including submarine hunting. The P3 is replaced by the P8 Poseidon aircraft, which uses a newer radar, designated AN/APY-10. The newer radar may use the same frequency range as the legacy APS-137(V), but that is not confirmed.

Please refer to the linked document from Forecast International for detailed technical information on the APS-137(V).

Possible extension of EESS (active) allocation (WRC-15 Agenda Item 1.12)

Proposed Use
9.9–10.5 GHz Possible extension of EESS (active) allocation (WRC-15 Agenda Item 1.12)
ITU World Radiocommunication Conference 2015 Agenda Item 1.12:

"To consider an extension of the current worldwide allocation to the Earth exploration-satellite service (active) in the frequency band 9300-9900 MHz by up to 600 MHz within the frequency bands 8700-9300 and/or 9900-10500 MHz, in accordance with Resolution 651 (WRC-12)"

Possible new FSS allocations, 2015 World Radiocommunication Conference (WRC-15) Agenda Item 1.6

Proposed Use
10–17 GHz Agenda Item 1.6.1 (Region 1)
1.6 to consider possible additional primary allocations:

1.6.1 to the fixed-satellite service (Earth-to-space and space-to Earth) of 250 MHz in the range between 10 GHz and 17 GHz in Region 1

1.6.2 to the fixed-satellite service (Earth-to-space) of 250 MHz in Region 2 and 300 MHz in Region 3 within the range 13-17 GHz;

and review the regulatory provisions on the current allocations to the fixed-satellite service within each range, taking into account the results of ITU-R studies, in accordance with Resolutions COM6/4 (WRC-12) and COM6/5 (WRC-12), respectively
