CHCNAV CGBAS

CGBAS employs advanced algorithms for ionospheric and tropospheric delay modeling, trained on extensive observation data. Real-time monitoring of data quality, baseline processing, ambiguity resolution in triangulated baseline networks, and ionospheric interpolation contribute to reliable GNSS RTK correction services.

CGBAS includes modules for station management, data processing, correction broadcasting, user management, coordinate systems, and online maps. It also offers post-processing capabilities through access to Rinex and a virtual Rinex engine.

CGBAS supports distributed and single-machine deployment, allowing users to select the optimal solution based on the number of base stations and terminal connections. Horizontal scaling ensures the system can expand to higher specifications without interrupting operations.

With backup and load-balancing capabilities, CGBAS achieves up to 99.9% availability. Redundant, off-site dual backups, node self-healing, and automatic failover minimize the impact of server node failures. The microservices architecture enables management of over 5,000 stations and 100,000+ concurrent users.

CGBAS prioritizes data and network security by isolating internal and public networks and utilizing custom compression formats for one-way data transmission. To further protect against base station coordinate leakage, it offers coordinate offset functionality.

An online map and visual statistics enable continuous monitoring of data quality at both base stations and terminal endpoints. Alarms provide prompt notifications, improving operational timeliness and reducing pressure.

CHCNAV integrates auxiliary functions between the P5 station, CGBAS, and CHCNAV terminals. It broadcasts auxiliary positioning data to enhance terminal accuracy. It also supports batch receiver restarts, upgrades, and configurations, even when base stations lack public IPs.
