Louisiana's Statewide Real-Time GNSS Network for Precise Positioning

Operated by the LSU Center for GeoInformatics (C4G), C4Gnet.XYZ is a professional-grade Real-Time Network (RTN) delivering centimeter-level accurate Real-Time Kinematic (RTK) corrections across the entire state of Louisiana. Subscribers achieve high-precision GNSS positioning without setting up or maintaining a local base station.

Key Benefits

• Exceptional Accuracy — Typically centimeter-level (within the 3D volume of a golf ball in real time), directly tied to the National Spatial Reference System (NSRS) using NAD83(2011) Epoch 2010.00.
  
• True Mobility — Reliable real-time corrections via cellular internet (NTRIP protocol). No base station required—faster setups, less equipment, and greater field efficiency.
  
• Statewide Coverage — Powered by a dense network of over 137 Continuously Operating Reference Stations (CORS).

Wide Range of Applications

Ideal for:

• Land surveying (design/stakeout, topographic surveys, boundary/right-of-way determination, project control, photogrammetric ground control, and more…)
• Construction and monitoring
• Asset inventory
• GNSS surveying
• Mobile mapping
• Precision agriculture
• GIS data collection
• Emerging uses like autonomous vehicles

Advanced GPS/GNSS Processing Technology

• Virtual Reference Station (VRS): Uses a network of fixed GNSS (Global Navigation Satellite System) reference stations and a central server to create a "virtual" base station near a user's rover, and by modeling atmospheric and other errors for consistent high accuracy positions, delivering real-time, centimeter-level positioning corrections via the internet, eliminating the need for a physical base station.
  
• Point Positioning (PPP) using RTXNet Processors: Integrates with proprietary RTX (Real-Time eXtended), a Trimble RTX technology for enhanced reliability, multi-constellation support (GPS, GLONASS, Galileo, BeiDou), and robust performance in challenging conditions.
