maintain the interoperability between
MODE S equipped and non-MODE S
equipped ground stations. This simulation
studied the transition issues.
EATMP REFERENCE INDUSTRYBASED
ATM SIMULATION AND
TRIALS PLATFORM (ERIS)
In 2002, ERIS became established as
an important enabler for the EATMP
validation programmes and the
European Commission抯 applied
research programmes. During the year,
the ERIS teams continued to upgrade
the ESCAPE (EUROCONTROL
Simulation Capability and Platform
for Experimentation) simulator platform,
notably in the areas of datalink
functions, open systems architecture
and live trials capability. Involvement
with partners from industry was
sustained.
Datalink
ESCAPE抯 datalink module enables
data communications between ground
and air systems. It has been implemented
using an architecture that
eases the distribution of functions
across the platform and helps to integrate
new components, improving
portability and interoperability. The platform,
with its datalink capability, was
used successfully during 2002 for
experimentation in the LINK2000+ and
DOVE projects.
Open architecture
A major milestone for ERIS was the delivery
in September of the first prototype of the
AVENUE-compliant ESCAPE open systems
architecture simulation platform. A successful
demonstration was performed in October
with a full set of simulation exercises of six
controllers and two pilots. Its behaviour
compared very favourably to that of the non-
AVENUE ESCAPE version and the users
reported very positively on the general platform
response-time. ACE is capable of running
a set of controller positions on mixed
hardware such as HP or SUN stations and
PC-Linux in any combination.
Live trials
The PROVE platform has been developed
and deployed for use in live trials. March
2002 saw the successful completion of a
shadow-mode trial in Malm?demonstrating
the EATMP medium-term conflict detection
operational concept.
During 2002, the PROVE (European ATC
Pre-operational Validation and Experimental
Trials) platform lost its separate identity as a
specific version of ESCAPE. The difficult
task of integrating all the live interfaces and
the ground adaptations into the regular realtime
version was completed. The full
datalink functionality is included. So now the
same version of ESCAPE can be used in
both 憀aboratory?and 憀ive?conditions. This
means that the validation of new concepts
and technologies can more easily be moved
from experimentation to pre-operational conditions.
Involving industry
One of the priorities for the ERIS Programme
is to involve industry in the provision of components
for ATM validation platforms. The
adaptation of ESCAPE to AVENUE standards
is an important step forward in this
respect. During 2002, ERIS worked with
INDRA, AENA, Barco-Orthogon and Thales
ATM on the integration of a range of components
into the simulator.
SATELLITE NAVIGATION
2002 was another important and eventful
year for GNSS. All the SBAS (Space
Based Augmentation Systems) and
GBAS (Ground Based Augmentation
Systems) activities continued to benefit
from the full support of stakeholders.
The common aviation community position
on GNSS aviation needs, coordinated
with airspace user associations and
air navigation service providers and
endorsed by the ATM/CNS Consultation
Group (ACG) in 2001, was agreed by
the Provisional Council. In support of this
common position, a study was launched
to look at the feasibility of the concept of
sole service GNSS. Another study was
launched to assess the vulnerability of
an ECAC navigation infrastructure based
on GNSS and look at possible mitigation
means. Both studies will be reported on
in 2003.
Ground-based augmentation
systems
The timeframe of the Project has been
expanded to 2006 to enable the implementation
of Ground-Based
Augmentation System (GBAS) CAT-I and
conduct R&D on potential other applications,
including CAT-II & III.
In 2002, the GBAS Project has made
major progress on activities related to
operational validation and safety assessment.
For the former, EUROCONTROL is
developing a tool referred to as GBAS
Modular Analysis and Research System
(MARS), which will assist air traffic service
