Standardisation Activity for Galileo

SAGA

Standardisation Activity for Galileo

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.

Key Results: 

The overall progress made on GALILEO standardisation through SAGA project is
significant and the results are globally in line with the initial objectives.

The main results and recommendations on future GALILEO standardisation are
actually specific to each of the domains. They are detailed per applications in chapter 3 and
an overview is provided in the executive summary. The general SAGA results that can also
be identified are following one:

  • GALILEO system is now introduced and recognised as a future GNSS positioning
    standard in major domains (Air, Maritime, Road, and Rail);
  • Most of the standards are ready to include potential benefits from combined GALILEO
    / GPS standards;
  • An efficient feedback from standardisation point of view has been provided by SAGA on
    GALILEO system definition and this will ease future standardisation;
  • The draft of standards produced for each domain represent an important first step on the
    overall standardisation process. Main standardisation issues have been preliminary
    assessed, proposals have been made on most important requirements to be standardised
    and have been discussed within the standardisation bodies;
  • A road map and recommendation for further work exist for each domain.

The SAGA
experience has also shown that two different categories of standardisation activities exist:
the safety of life related applications for which standards are driven by regulations and
the mass market for which the driver is commercial.
Finally it has to be highlighted that such support activities to future GALIELEO
standards initiated d by SAGA should be continued in the next years. This is t essential to
consolidate and finalise standards before GALILEO operational use.

Technical Implications

Air

The objectives pursued by the consortium during the four years of the project can be
summarised as follows:

  • Definition of existing civil aviation standardisation framework for signal in space and
    user receivers. The purpose it to identify the mechanisms and bodies in charge of
    standardisation at international and national levels.
  • Presentation and promotion of Galileo to the civil aviation community. The purpose is to
    present the main technical features considered for system design and the corresponding
    expected performance. The main expected result of this activity is to get feedback from
    the user community on the proposed definition.
  • To review and provide feedback on the key Galileo definition documents.
  • To support the Galileo standardisation activities within the ICAO GNSSP and Eurocae
    WG62.
  • Drafting of initial standards. This includes draft ICAO SARPs for the Galileo signal-inspace,
    draft MOPS for the airborne receiver, and outline standards for the Galileo local
    component for aviation.

These initial objectives were refined during the course of the project in consultation with the
EC. The refinements changed the focus of the work to some extent but did not significantly
change the overall objectives. Some example of this were:

  1. The work on drafting standards within ICAO did not proceed as rapidly as initially
    expected. Additional work was carried out analysing such as GNSS vulnerabilities and
    the benefits of combining Galileo and GPS in the user receiver. The main objective of
    this work was to ensure that the benefits of Galileo were recognised within ICAO and
    specifically at the 11
    th
    Air Navigation Conference, held in October 2003.
  2. Work within Eurocae WG62 was focussed mainly on issues such as the Concept of
    Operations for combined Galileo/GPS receivers an
