Design and Development of Railway Beidou/GNSS Reference Service Platform
In order to further improve the service efficiency and information level of railway control network,and to achieve automatic maintenance of railway engineering datum remeasurement,a railway Beidou/GNSS(Global Navigation Satellite System)reference service platform was put forward in this paper,the judgement method of stable and changing points in control network remeasurement was analyzed,the self-maintenance process of position datum was proposed.Combining Internet communication and satellite positioning technologies,the research and development process of the railway Beidou/GNSS reference service platform was discussed from the aspects of key technologies,framework design and module research and development.The system can achieve automatic maintenance of reference station position,high-precision broadcasting of terminal equipment positioning,reduce the workload in the process of line re-testing,and reduce part of the cost for railway engineering operation and maintenance.
