During the acceptance phase of the Hotan-Ruoqiang Railway, the SpatiX Xstar service assisted builders in quickly collecting high-precision position data of numerous key devices along the line, laying the foundation for safe scheduling and efficient operation and maintenance after the railway's official operation.
The construction process of the Hotan-Ruoqiang Railway was extremely difficult. This railway, stretching from Hotan to Ruoqiang in Xinjiang, has a total length of 825 kilometers and is located on the southern edge of the Taklimakan Desert, known as the "Sea of Death." Approximately three-quarters of its length passes through deserts and gobi, and it took 3 and a half years to finally complete.
During the railway acceptance phase, builders needed to collect accurate position information of key facilities such as the main railway line, station tracks, trackside equipment, and auxiliary facilities to provide data support for the safe operation and maintenance of the railway. However, accomplishing this task in the desert was no easy feat.
Typically, precise position information can be obtained using ground-based augmentation services, but such services rely on communication networks. About 60% of the Hotan-Ruoqiang Railway passes through sandy and windy sections, and most areas along the line lack infrastructure such as communication, power supply, and transportation, making the ground-based augmentation service unavailable.
To address this challenge, the SpatiX Xstar service can provide fast, real-time high-precision positioning services in deserts and other areas without the need for control surveys, additional ground-based augmentation stations, or communication facilities, significantly improving work efficiency.
Verified by the Hotan-Ruoqiang Railway project, the convergence time for centimeter-level positioning using the SpatiX Xstar service's data collection terminal is less than 2 minutes, and the positioning accuracy after convergence is better than 2 centimeters at its highest. Additionally, SpatiX's terminals can directly output results in coordinate systems such as CGCS2000 and WGS84 without the need for additional conversion work.
In addition to its practical application in desert areas, as the world's first high-precision location-based service (LBS) to pass a series of functional safety certifications, the SpatiX Xstar service has also undergone extensive verification on urban roads, expressways, and major border areas in China, and has been commercially applied in fields such as surveying and mapping, precision agriculture, precise power inspection, and marine vessel positioning systems.
