Study on feasibility of SATCOM for railway communication

Final Report
2.4 STUDY METHODOLOGY
The methodology followed to complete the objectives of this study is presented in Figure 8, where the
work to be performed has been broken down in four main tasks:
- Task 1: Identification of the parameters and criteria (technical, multi-technology and nontechnical)
for the subsequent assessment of SATCOM solutions.
- Task 2: Detailed analysis of the satellite communication market with respect to the candidate
solutions and technology to be adopted in railway domain. This second task also includes a
consultation process in order to identify the trends and manufacturers‘ roadmaps regarding
SATCOM solutions.
- Task 3: The activity in task 3 is split into three main tasks
o Analysis of solutions and technologies regarding criteria and parameters from task 1
(e.g. performance, functional, technical, cost, etc)
o
o
Criteria assessment by using a compliance matrix with all railway communication
requirements and candidate solutions.
Identification of the deployment and operational requirements or contour conditions.
- Task 4: Drawing conclusions and recommendations taking into account the results of the
previous tasks. It also provides answers to the questions requested by the Agency as a main
objectives of this study. In addition, a Business Case Analysis taking into consideration the
potential introduction of additional services provided by the solutions proposed (e.g. nonsafety
or mission-critical services) is performed.
