Study on feasibility of SATCOM for railway communication

Final Report

1.3 IDENTIFICATION OF CRITERIA FOR THE ASSESSMENT OF SATCOM SOLUTIONS
Three types of criteria have been identified for the subsequent assessment of the SATCOM solutions
proposed regarding their feasibility to support critical railway applications:
Technical and functional criteria
Multi-technology criteria
Non-technical and non-functional criteria
A high-level definition similar to the one used within the URS document [AD-01] has been used in the
description of the criteria identified.
The tables below summarise the criteria to be applied to the proposed SATCOM solutions.
Technical and functional criteria
Criterion ID
Criterion
CRT-TECH-1
CRT-TECH-2
CRT-TECH-3
CRT-TECH-4
CRT-TECH-5
CRT-TECH-6
CRT-TECH-7
The ―link availability‖ of the proposed SATCOM system shall be High.
The ―reliability‖ of the proposed SATCOM system shall be High.
The end-to-end error ratio of the proposed SATCOM system shall be Low.
Transfer delay for the proposed satellite system shall be Low.
Delay jitter of the proposed SATCOM system shall be Low.
Network registration delay shall be Normal (with similar values to GSM-R).
The call establishment delay for the proposed SATCOM system shall be Low.
