衛星通信在高速鐵路系統中的應用探討

Abstract

本研究概述衛星通信在高速鐵路系統中應用的現狀與前景，提出利用衛星通信的接入方案配合GSM-R系統進一步增強高速鐵路運行的安全性和魯棒性。從技術和經濟的角度探討該方案的可行性。The situation and outlook of satellite net-works used in high speed railway were outlined. Also, it was proposed that, besides GSM-R, satellite access scheme should be introduced into high speed railway system to enhance the safety and robustness of system. Feasibility of the proposed scheme was discussed from the view of technology and economy.
