China will use the BeiDou satellite-based augmentation system (BDSBAS) to provide positioning services in railway surveys and construction, reported the China Railway Siyuan Survey and Design Group and Xinhua Net.
Four satellite-based and 12 ground-based observation stations will be placed along the Wufeng-Enshi railway section located in the Hubei Province in central China.
The BDSBAS and the BeiDou ground-based augmentation system aim to further enhance railway survey efficiency.
