摘要

本文从PVT精度和完整性信息两方面比较了EGNOS系统与用于列车定位的增强与完整性监测网络(AIMN)定位系统(LDS)的性能。提出的工作插入到基于ERTMS架构的空间技术引进和应用的场景中。该公司预计将EGNOS-Galileo基础设施纳入列车控制系统,目的是提高性能,增强安全性,减少对铁路电路及其维护的投资。性能结果将基于在意大利罗马附近的环形高速公路(名为Grande Raccordo Anulare (GRA))上进行的战役测试,以模拟火车在普通轨道上的运动。

Augmentation and Integrity Monitoring Network and EGNOS performance comparison for train positioning
The paper describes the performance comparison between EGNOS system and an Augmentation & Integrity Monitoring Network (AIMN) Location Determination System (LDS) designed for train positioning in terms of PVT accuracy and integrity information. The proposed work is inserted in the scenario of introduction and application of space technologies based on the ERTMS architecture. It foresees to include the EGNOS-Galileo infrastructures in the train control system, with the aim at improving performance, enhancing safety and reducing the investments on the railways circuitry and its maintenance. The performance results will be shown, based on a campaign test acquired on a ring-shaped highway (named Grande Raccordo Anulare (GRA)) around Rome (Italy) to simulate movement of a train on a generic track.
