Mobile satellite measurements on the Pomeranian Metropolitan Railway

Topological Analysis of Tokyo Metropolitan Railway System

High Assurance System for the Tokyo Metropolitan Area Railway Network

L Introduction Large-scale public systems in today’s information control field require. that seveml conditions should be satisfied. Fmt, a phased-in construction of the system must be possible so that the system can be constructed over a long period of time. Second the system must be flexible and be adapted to meet the changes of social needs. All such systems are assumed to constantly grow, ex...

On the satellite diversity in CDMA based mobile satellite systems

With non-GEO constellations the primary means of counteracting the shadowing and the blockage effects is through the use of the satellite diversity, i.e. multiple satellites in the constellation are simultaneously visible to user. The probability system availability is improved by increasing the probability at least one satellite is in clear Line Of Sight. In the selection diversity (SD) scheme...

The Use of Modern Satellite Systems in the Railway Traffic

In this paper the satellite-based railway positioning systems are summarised. In the first part the advantages of the satellite-based railway systems, short summary of the GPS system and the application today are given. Further on a system model is presented which can help us to survey the whole transport process.

Mobile Metropolitan Ad hoc Networks

The aim of this deliverable is to provide the software that implements, on the Linux operating system, the functions required to set up a MobileMAN. Specifically, in addition to the revised version of the software modules already delivered in D11 -i) CORE watchdog mechanism, ii) ad hoc routing framework, iii) p2p Pastry platform, and iv) VoIP and whiteboard applications -we now also deliver: th...
