WRC03 AERONAUTICAL FREQUENCY WRC 2003 OUTCOMES FOLLOW-UP ACTION AGENDA SERVICE ITEMS AFFECTED

1.1 Country names have been added and deleted to many Analyse footnotes footnotes. Benefit and drawback for aviation have still to be accessed.

1.4 ARNS (incl MLS) 5091-5150 MHz No additional allocation in this ARNS band, shared with FSS. Note the change of dates when This is in line with aviation position and will still permit developing a possible MLS deployment of ARNS systems (including extension of MLS). extension plan. FSS operation will become secondary in 2018 instead of 2012. Contribute to ITU-R study on New FSS frequency assignment is permitted until 2012 instead compatibility with FSS Monitor at of 2006. This has no impact on the core MLS band below 5091 next WRCs, attempt to introduce MHz, but may delay introduction of new aeronautical systems, if new allocations. 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.

1.5 ARNS, including 5150-5725 MHz The radiolocation service in 5350-5470 MHz is now upgraded None weather radar 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.

1.6 ARNS 5150-5250 MHz This band, although containing an ARNS allocation, is not used None 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.

General Contribute to ITU-R study on measurement methods have been specified for radar. ITU-R is magnetron radar. 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.

1.8.2 passive service Maximum emission limits to protect the passive service have None been further defined, which did not seem to impact aviation systems.

1.11 AMSS 14-14.5 GHz As supported by aviation, allocation for airline satellite None communication (Connexion by Boeing) is accepted on a secondary status.

1.14 HF AM®S 2-28 MHz As requested by aviation, WRC03 defined methodology to Monitor and participate to the alleviate cases of interference. application of the methodology for aeronautical communication.

1.15 (res DME and GNSS 1 164 – 1215 MHz The aggregate radiation limit of RNSS operating in 1164-1215 monitor US/Europe co-ordination 605) MHz proposed by aviation is agreed. In addition RNSS should procedure on GPS/Galileo signals 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.

1.15 (res RADAR 1 215 - 1300 MHz A footnote requesting protection of radar from RNSS emission is Contribute to ITU-R studies on the 606) accepted. The mechanism using limitation of RNSS radiation is protection of radar. 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.

1.15 MLS An aggregate power limit for the RNSS operating in 5010-5030 None MHz is agreed to protect MLS above 5030 MHz.

1.17 Radiolocation 2900-3100 MHz Upgrade of Radiolocation without adding more constraints to the None ARNS is agreed. That is in line with aviation position.

1.22 IMT-2000 Additional allocation for IMT-2000 (UMTS in Europe) should be Monitor development to find found for WRC07. There is a threat than under-used aviation additional allocation for IMT-2000. bands can be reviewed for that purpose.

1.28 GBAS, VDL 108-118 MHz GBAS allocation is accepted on 108-118 MHz. Surveillance Contribute to compatibility studies 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.

1.31 MSS 1 to 3 GHz MSS has got the additional spectrum allocations. Allocation in None 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.
