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

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

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/L5 is reportedly backed by Google.
