I. Railway Beidou Satellite Service Platform
Functions and Features
The Railway Beidou Application Service Platform provides high-precision positioning, timing, and short-message information services for terminal equipment. At the same time, it provides location, short-message, and status information for business systems and integrated communication networks, and also provides spatiotemporal information for the railway data service platform. Specifically, it includes:
Unified Provision of High-Precision Positioning Services: Provides users with real-time positioning services with centimeter-level to sub-meter-level accuracy and quasi-real-time positioning services with millimeter-level accuracy.
Unified Provision of Timing Services: Provides accurate timing services for terminal equipment and business application systems.
Unified Provision of Communication Services: Provides short-message communication services between terminal equipment, between terminal equipment and the Beidou platform, and between terminal equipment and ordinary mobile phone users.
Unified Management of Whole-Network Equipment: Accurately grasps the online status and location of satellite navigation application equipment across the entire railway network, and realizes the comprehensive display of online equipment across the entire railway.
Spatiotemporal Information Sharing: Provides spatiotemporal information of online equipment for the railway data service platform, supports big data analysis based on spatiotemporal information, and enables spatiotemporal information sharing with other industries and enterprises outside the railway sector.
II. On-Board Beidou High-Precision Spatiotemporal Reference Unit
(1) Application Scenarios
It is mainly used to build the on-board spatiotemporal reference for mobile equipment, ensuring the consistency, safety, and reliability of the railway on-board spatiotemporal reference system, and providing high-precision positioning and timing services for on-board equipment.
(2) System Composition
It is composed of a spatiotemporal reference unit, a transmission network, the Railway Beidou Application Service Platform, and the station-level ground system. When the train is in an environment without satellite signals, it can use the built-in high-precision inertial navigation module, radar, and time taming module to continuously provide services for on-board equipment.
(3) Core Functions
High-Precision Positioning: The reference unit receives the differential service broadcast by the Railway Beidou Application Service Platform and provides high-precision positioning services for railway on-board equipment.
Time Synchronization: The reference unit takes GNSS satellite time or a ground clock source as the reference and provides time information for other on-board systems through standard timing interfaces, realizing time synchronization of all on-board equipment.
Wireless Data Transmission: The reference unit can provide high-speed wireless data transmission services for itself and other on-board equipment.
Data Encryption and Decryption: The reference unit can encrypt and decrypt the data transmitted by on-board equipment to ensure the security of data transmission.
