PHOTO IC WUHAN - China will employ the BeiDou satellite-based augmentation system BDSBAS to provide high-precision positioning service in railway survey and construction, according to the China Railway Siyuan Survey and Design Group Co, Ltd.
Four satellite-based and 12 ground-based observation stations will be set up along the Wufeng-Enshi railway line in central China's province of Hubei.
The company said that the BDSBAS will be used in the field of intelligent railway surveys for the first time.
Users can access the real-time centimeter-level positioning service after receiving relevant signals through a wireless network or satellite to earth communication.
The BDSBAS is more efficient in network construction and wide-range constant positioning in mountainous regions compared to the BeiDou ground-based augmentation system BDGBAS.
The construction of BDSBAS and BDGBAS in the Wufeng-Enshi section will further improve railway survey efficiency and lay the foundation for high-precision geographic information services of intelligent survey and design, said the company.
