The group discussed agenda item 1.6, Resolution 415, which considers “additional allocations for the aeronautical mobile service in parts of the bands between 108 MHz and 6 GHz, in accordance with Resolution 414 (WRC-03) and, to study current satellite frequency allocations, that will support the modernization of civil aviation telecom systems, taking into account Resolution 415 (WRC-03).” While the issue was defined as looking at creating broader satellite frequency allocations to include civil aviation telecom systems and other non- aeronautical telecom services while remaining compatible with existing allocations, there was group discussion about whether the inclusion of “non-aeronautical services” was necessary. Draft author David Weinreich of Connexion by Boeing said it was important not to restrict the frequencies to only aeronautical uses, but also fixed satellite service (FSS) applications in remote areas. A 2nd draft for agenda item 1.21 created little discussion. The item proposes “to consider the results of studies regarding the compatibility between the radio astronomy service and the active space services in accordance with Resolution 740 (WRC-03), in order to review and update, if appropriate, the tables of threshold levels used for consultation that appear in the Annex to Resolution 739 (WRC-03).” IWG-2 plans to meet May 27 in order to finalize preliminary views on both agenda items before the June 8 meeting of the WRC-07 Advisory Committee.
