The following draft paper on the Amateur Satellite Service Spectrum is being submitted by the RSGB to the IARU Region 1 Interim Conference in Vienna. --------------- International Amateur Radio Union Region 1
Interim Conference, Vienna, 24 to 25 February 2007
Subject Amateur Satellite Service Spectrum Society Radio Society of Great Britain Committee C5 - VHF/UHF/Microwave Committee Contact Murray Niman G6JYB, (Microwave Manager)
Background
The Amateur Satellite Service is faced with more restricted allocations than the Amateur Service, and this is compounded by both interference threats and other restrictions that inhibit harmonised usage.
Considering that
· There are increasing levels of harmful interference from ISM etc in the 2.4GHz band
· There are concerns regarding radars and Galileo in 23cms
· Region 1 does not have any Amateur Satellite allocation in the 3.4GHz band, in contrast to Regions 2& 3 (not even within CEPT EU-17/23)
· The 6 metre band is increasingly allocated as an amateur allocation by many countries
· That Wimax, Fixed Wireless Access and future Intelligent Transport Systems threaten the 5.8GHz Space-Earth allocation.
· Some allocations are additionally restricted by being Earth-Space or Space-Earth only.
· Satellites can have a significant in-service lifetime that can complicate a phased frequency migration
Proposals
All IARU Region 1 societies request that the following additional Amateur Satellite Service bands be studied and considered, perhaps as a package, for a future WRC agenda item
50-51 MHz 1240-1250 MHz 2300-2330 MHz 2390-2400 MHz 3400-3410 MHz 5650-5670 MHz (Currently Earth-To-Space only) 10350-10400 MHz
