Rep. of the Congo, Singapore, Somalia, Sudan, South Sudan, Chad, Togo and Yemen, the frequency band 15.7 17.3 GHz is also allocated to the fixed and mobile services on a primary basis. (WRC 15)

5.513 Additional allocation: in Israel, the band 15.7-17.3 GHz is also allocated to the fixed and mobile services on a primary basis. These services shall not claim protection from or cause harmful interference to services operating in accordance with the Table in countries other than those included in No. 5.512.

Band Uses (17.2 - 17.3 GHz)

DISH Network

DISH network uses the 12.2-12.7 GHz band for its direct broadcast satellite TV service. This is the band received by customers who subscribe to the DISH Network service. The satellites also transmit relatively narrowband (300 kHz-1 MHz) telemetry, tracking, and control (TT&C) signals in this band, primarily in the lower and upper few MHz of the band.

DISH uses 17.3-17.8 GHz for feeder links (uploading the TV signals from the ground to the satellites), from earth stations located in Cheyenne, WY, and Gilbert, AZ. It also sends relatively narrowband (36 kHz-800 kHz) telemetry, tracking, and control signals to the satellites from these earth stations, primarily in the lower and upper few MHz of the band.

WRC-23 Agenda Item 1.19, Consider New FSS S2E Primary Allocation in Region 2

"to consider a new primary allocation to the fixed-satellite service in the space-to-Earth direction in the frequency band 17.3-17.7 GHz in Region 2, while protecting existing primary services in the band, in accordance with Resolution 174 (WRC-19);"

SkyBridge

SkyBridge LLC filed in 1997 with the FCC to provide fixed-satellite service operations from a network of 80 non-GSO satellites, operating 4 satellites per plane in 20 planes, inclined 53 deg. The satellites would be in circular orbits at an altitude of 1469.3 km. The FCC granted launch and operation authority to SkyBridge in 2005 (DA 05-2037), but SkyBridge was never launched.

In 2014, a company registered/operating under the names L5 and WorldVu, based in the Channel Islands, acquired SkyBridge's Ku-band spectrum rights at the ITU. According to a May 30, 2014, Space News article, WorldVu would consist of 360 small satellites operating at between 800 and 950 km altitude at an inclination of 88.2 deg (near polar orbit). Space News quotes the filing as indicating the satellite system would come into use in 2019 or 2020.

WorldVu is now known as OneWeb.

WRC-27 agenda item for new primary FSS and BSS allocations and EPFD limits

WRC-27 Agenda Item 1.4:

to consider a possible new primary allocation to the fixed-satellite service (space-to-Earth) in the frequency band 17.3-17.7 GHz and a possible new primary allocation to the broadcasting-satellite service (space-to-Earth) in the frequency band 17.3-17.8 GHz in Region 3, while ensuring the protection of existing primary allocations in the same and adjacent frequency bands, and to consider equivalent power flux-density limits to be applied in Regions 1 and 3 to non-geostationary satellite systems in the fixed-satellite service (space-to-Earth) in the frequency band 17.3-17.7 GHz, in accordance with Resolution 726 (WRC-23)
