Study on feasibility of SATCOM for railway communication

Final Report
2.5 DOCUMENT STRUCTURE
This document is structured into the following sections:
Section 3 provides the main results of the analysis of the railway applications described in the
URS document [AD-01], a main input for this study.
Section 4 introduces Satellite Communications Systems adapted to railway applications.
Section 5 summarises the identified criteria to be evaluated against the proposed satellite
communications systems.
Section 6 presents the SATCOM solutions identified in the market survey.
Section 7 lists a pre-selection of SATCOM solutions to be analysed and describes why some
of the solutions identified in the market survey are discarded in advance.
Section 8 shows the main conclusions of the consultation process carried out to the SATCOM
and railway markets regarding their views about SATCOM for railways.
Section 9 provides the assessment of SATCOM solutions based on technical, multitechnology
and non-technical criteria. This section also shows the methodology followed in
the cost analysis study and CBA for both SATCOM and terrestrial solutions and their delta
cost regarding current GSM-R.
Section 10 shows the operational and deployment conditions of SATCOM for railways.
Section 11 presents the conclusions and recommendations of this study.
Section 12 provides answers to the ToR questions.
In addition, this Final Report includes a number of annexes containing extra material:
Annex A shows the criteria identification, including justification and traceability.
Annex B presents the questionnaire used for the consultation process.
Annex C provides the technical assessment of each SATCOM solution with justifications.
