SAGA - Standardisation Activity for Galileo
Overview
Background & policy context:
SAGA (Standardisation activities to GALILEO) is a four years EC project launched
in December 1999 to support GALIEO standardisation activities with the aim to secure world
wide recognition and acceptance of GALILEO as future GNSS standard. This was identified
and is still of utmost importance to trigger development of future GALILEO based services.
To this aim the work plan was :
-
First to output at the end of the first year a report setting forth: organisation and workplan
for standardisation activity as well as results of preliminary analysis of important
standardisation issues. -
Then to develop and issue a first draft of standards document at the end of the second
year. -
Finally to consolidate this first draft during the two next years period in close coordination
with the standardisation towards a final draft ready for approval.
The overall progress made on GALILEO standardisation is important. The results
obtained are significant and in line with the initial objectives apart from slight changes agreed
at project mid term review.
Two main activities were stopped: the work on common standardisation issues due
fewer needs on common actions in the second phase of the project, the work on detailed
receiver’s standards for some applications that were less demanding.
It was also recognised that the maturity of standards could not be as high as initially
expected. Firstly GALILEO definition has progressed lower than planned and secondly more
effort was needed to promote GALILEO within the standardisation bodies.
The Results and recommendations on standardisation are specific to each of the
domain and are summarised in dedicated paragraphs below. Nevertheless some of the general
SAGA results are to be highlighted:
-
GALILEO system is now introduced and recognised as a future GNSS positioning
standard in major domains (Air, Maritime, Road, and Rail).
Objectives:
The objective of SAGA was to support GALILEO standardisation activities so that GALILEO becomes recognised and adopted world wide as a GNSS system standard. For various reasons depending on the applications this is indeed absolutely needed to secure development of future GALILEO based services. This includes also interoperability constraints with other current GNSS standards such as GPS and its modernisation.
To this high level aim the SAGA project’s activities have been organised with two main technical objectives as targets:
- The first objective was to set up the basis for a continuous GALILEO standardisation activity covering the whole definition and development phase of the program. This objective was tobe completed through a preparation phase covering the first year (2000) of the study.This was including: identification of real needs, standardisation bodies involved preliminaryanalysis of important standardisation issues, work plan and recommendations.
-
The Second objective was to issue a set of first draft standards for GALILEO and to improve it through presentation and discussion in the framework of the relevant standardisation bodiesup to the level of maturity required for formal approval. This second objective has been proposed to be achieved in two steps:
- Second year (2001): set of first draft development
- Third and fourth years (2003-2004): consolidation of draft towards final draftready for formal
- approval in the framework of the relevant standardisationbodies.
Such activity was clearly planned to make use and to interact with the most up to date
technical GALILEO definition results as soon as available, and consequently the SAGA work
plan was including such co-ordination activities with other GALILEO projects.
Methodology:
The consortium has operated during the four years project time frame in an efficient
manner in meeting the EC needs for useful deliverables and actions on time to support
GALILEO standardisation in all targeted domains and associated bodies.
This has been accomplished during the first period (2000-2001) in a difficult external
SAGA environment with political GALILEO uncertainties and slow down periods in the
technical progress of Galileo definition. This has also required even more flexibility reactivity
and effort from partners than initially planned.
This has also required a continuous motivation and effort in the second period (2002-
2003) to progress efficiently and on time with limited budget on the final drafting of
standards and on promotion towards standardisation bodies.
The exchanges among the partners responsible for different standardisation areas
have been encouraged in the first phase by the “common approach” activity (WP 1000) and
were still activated after through the periodic project progress meetings.
