WRC03 AGENDA ITEMS / AERONAUTICAL SERVICE AFFECTED / FREQUENCY /WRC 2003 OUTCOMES
/FOLLOW-UP ACTION
1.1 / Country names have been added and deleted to many footnotes. Benefit and drawback for aviation have still to be accessed. / Analyse footnotes1.4 / ARNS (incl MLS) / 5091-5150 MHz / No additional allocation in this ARNS band, shared with FSS. This is in line with aviation position and will still permit deployment of ARNS systems (including extension of MLS). FSS operation will become secondary in 2018 instead of 2012. New FSS frequency assignment is permitted until 2012 instead of 2006. This has no impact on the core MLS band below 5091 MHz, but may delay introduction of new aeronautical systems, if aviation has a requirement for them. ITU request to study compatibility between new nautical systems and the FSS. The aeronautical and the FSS allocation will be reviewed at a WRC prior 2018. / Note the change of dates when developing a possible MLS extension plan.
Contribute to ITU-R study on compatibility with FSS Monitor at next WRCs, attempt to introduce new allocations.
1.5 / ARNS, including weather radar / 5150-5725 MHz / The radiolocation service in 5350-5470 MHz is now upgraded to a primary status. A new space research service has been introduced in 5350-5460 MHz. These 2 new allocations have been made under the conditions they do not create harmful interference to airborne radar. That is in line with aviation position. / None
1.6 / ARNS / 5150-5250 MHz / This band, although containing an ARNS allocation, is not used by aviation and was allocated many years ago to non aviation services. WRC03 allocated RLAN under "mobile except aeronautical mobile". The unsuitability of this band for the development of future safety aeronautical service is now reinforced. / None
1.8.1 / general limits / The boundary between unwanted and spurious emissions has been defined and will be applicable to new transmitters installed after 2003 and to all transmitters after 2012. General measurement methods have been specified for radar. ITU-R is invited to study method to determine the boundary between unwanted and spurious emissions specifically for primary radar using magnetron, as the actual method may underestimate the radar bandwidth. The consequence of these new regulations has still to be assessed, especially for primary and secondary radar. / Verify that ICAO specification are in line with the new ITU regulation. Contribute to ITU-R study on magnetron radar.
1.8.2 / passive service / Maximum emission limits to protect the passive service have been further defined, which did not seem to impact aviation systems. / None
1.11 / AMSS / 14-14.5 GHz / As supported by aviation, allocation for airline satellite communication (Connexion by Boeing) is accepted on a secondary status. / None
1.14 / HF AM®S / 2-28 MHz / As requested by aviation, WRC03 defined methodology to alleviate cases of interference. / Monitor and participate to the application of the methodology for aeronautical communication.
1.15 (res 605) / DME and GNSS / 1 164 – 1215 MHz / The aggregate radiation limit of RNSS operating in 1164-1215 MHz proposed by aviation is agreed. In addition RNSS should not claim protection from the DME operating in the complete band (960-1215 MHz). Due to an US/Europe dispute on the way to achieve equitable sharing of power energy between RNSS operators, the conference introduced a complex co-ordination mechanism between administrations and operators. / monitor US/Europe co-ordination procedure on GPS/Galileo signals
1.15 (res 606) / RADAR / 1 215 - 1300 MHz / A footnote requesting protection of radar from RNSS emission is accepted. The mechanism using limitation of RNSS radiation is not accepted. This is compliant with co-ordinated aviation position, while some aviation persons would have preferred a method with a limit. No additional constraint can be placed on RNSS assigned before WRC2000. ITU-R is invited to continue studies related to the protection of radar. / Contribute to ITU-R studies on the protection of radar.
1.15 / MLS / An aggregate power limit for the RNSS operating in 5010-5030 MHz is agreed to protect MLS above 5030 MHz. / None
1.17 / Radiolocation / 2900-3100 MHz / Upgrade of Radiolocation without adding more constraints to the ARNS is agreed. That is in line with aviation position. / None
1.22 / IMT-2000 / Additional allocation for IMT-2000 (UMTS in Europe) should be found for WRC07. There is a threat than under-used aviation bands can be reviewed for that purpose. / Monitor development to find additional allocation for IMT-2000.
1.28 / GBAS, VDL / 108-118 MHz / GBAS allocation is accepted on 108-118 MHz. Surveillance datalink (VDL4) allocation is accepted in 112-118 MHz as a first step. Allocation down to 108 MHz will be possible when compatibility studies in ITU-R are completed. Radio regulation is requesting that the 2 new systems should not cause interference to existing systems (ILS and VOR), and that they shall not cause additional constraint to the FM broadcast service, including the future digital broadcast system, in the band below 108 MHz. / Contribute to compatibility studies
1.31 / MSS / 1 to 3 GHz / MSS has got the additional spectrum allocations. Allocation in aeronautical telemetry band (1.4 GHz) is avoided at that WRC. MSS (earth to space direction) has got an allocation in the band 1670-1675 MHz granted for passengers communications (TFTS earth stations). This has no impact on aviation as the TFTS system is and is not foreseen to be deployed. The result is in line with aviation position. / None
7.2 Agenda for WRC07 / Aeronautical wide band telemetry / Consider possible additional allocation for aeronautical wideband telemetry. / None it is an aircraft manufacturer matter
7.2 Agenda for WRC07 / Aeronautical terrestrial and satellite communications / WRC03 has joined 3 different requests from aviation in an agenda item for WRC07:
1)The request from Europe for a new 3G terrestrial aeronautical communication service between 108 MHz and 6 GHz
2) The request from the US and IATA for a new airport movement control system in the band 5091-5150 MHz, originally intended for MLS extension.
3) The request from Japan and developing countries to consider suitable allocation for modernising the aeronautical satellite communication infrastructure. An additional study on the access for AM(R)S specifically in the 1.5/1.6 GHz band is on the agenda for WRC2010. / 1)Europe having put the request, EUROCONTROL is expected to lead the 3G communication activity and will have to establish the structure and resource to progress development of a new 3G aeronautical communication systems for ATC purpose.
2)Support studies for the new airport system
3)Support study for the modernisation of AMS(R)S with the others region, taking into consideration the current development between ESA and EUROCONTROL on new AMS(R)S.
