Traffic needs The Aeronautical Mobile Communication infrastructure
needs, in congested airspace, to accommodate Traffic growth 8.33
over FL 245 in ECAC We will be somewhere here with 8.33 below FL
245 Capacity demand Ideal case: ALL airspace in 8.33 In any case a
gap will exist What is the foreseen situation for communication
resources in Europe Additional communication capacity needs to be
made available outside the VHF band 3-2 Slide 8 One Sky for Europe

Nov 02 Ed 1.1 Options Communication capacity has to be made
available outside the VHF band which is close to saturation in
Europe - even with 8.33kHz channels Eurocontrol is pursuing two
options - terrestrial-based using UMTS-type technology
satellite-based using enhancement of existing AMSS as a Next
Generation Satellite System - NGSS applicable to Europe and the
rest of the world Timescale is be operational by 2010 to 2015 3-5

26 Nov 02 Ed 1.1 Among candidate systems, geostationary
satellite-based technologies are considered promising due to their
: global nature - with global beams regional nature - with
regional/spot beams adaptability to specific airspace (e.g. low
density/oceanic airspace, upper airspace) adaptability to support
specific services (e.g. ground-to-aircraft broadcast). capability
to complement terrestrial systems (thus reducing pressure on the
VHF spectrum) Why satellite systems ? 3-8 Slide 14 One Sky for
Europe EUROCONTROL 2002 European Organisation for the Safety of Air
Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 26
Nov 02 Ed 1.1 What choices are there ? There are several current
(e.g. ICAO AMSS) or emerging satellite technologies (e.g. Iridium)
but they are designed to support shared use or non-safety traffic
only Some support AAC, APC - some may support AOC and ATSC as well
(e.g. AMSS) No system supports only AMS(R)S Previous experience has
shown that reliance on a shared business case can cause problems
Where safety and regularity of flight communications are to be
carried by a communications system specific measures must be put in
place to safeguard them 3-9 Slide 15 One Sky for Europe EUROCONTROL

1.1 What About the Current AMSS? Due to historical design choice,
the current AMSS has limitations Designed to meet full range of
users leading to more complex system design Expensive aircraft
installation and avionics Limited number of Large Ground Earth
Stations (GES) leading to limited options for communications
service provision No Guaranteed service restoration delay after
interruption Shared use of spectrum between safety and non-safety
services Perceived as only applicable to low density traffic areas
due poor performancebut 3-10 Slide 16 One Sky for Europe

terrestrial system (which will stay for the foreseeable future) is
a key feature The goal is that the NGSS has a similar Quality of

dependent on applications (ATS - Voice & Data; AOC Voice &
Data) Initial estimates show that approximately 4 MHz are needed in
ECAC using a regional beam Operates in the L-band (1.5 / 1.6 GHz)
where aviation is a privileged user but under threat There is
guaranteed long term availability of global coverage for safety
communications due to IMO (Maritime) obligation to support GMDSS

WRC 97, Aviation has lost its AMS(R)S (1.5 - 1.6 GHz) spectrum
exclusive allocation (14 10 0 MHz bandwidth), However, ITU
recognises aviation as priority users of the band pending on
supporting services in the 1 - 6 priority levels (according to ITU
definition) - ITU footnote S5.357A At Eurocontrols request, CEPT
CPG confirmed that, when Aviation is ready to operate the service,
Administrations will have to ensure access to the frequency in the
former AMS(R)S sub-band. Slide 47 One Sky for Europe EUROCONTROL

1.1 AMS(R)S spectrum availability ITU WP 8D is looking at the
feasibility of introducing priority/pre-emption of intra/inter
systems (resolution 222) Such a mechanism is not felt feasible
However, ITU did not define deadline for concluding the feasibility
study work (WRC06, WRC09 ?) The ICAO position is to ask WRC03 to
fix WRC06 as the target date to conclude and define relevant
further action Aviation spectrum managers should be pro-active in
supporting this position with their National Radio Regulators 6-9
