LSU Center for GeoInformatics invites qualified professionals* to subscribe to the C4G Real-Time Network! C4G RTN is a network of Continually Operating GPS Reference Stations (CORS) that delivers Real Time Network error corrections for GPS data providing the next step of sophistication serving the aims of research in surveying, geology, subsidence, hurricane safety engineering and much more. C4G RTN provides real-time data for use by surveyors, construction crews, precision farming and others with appropriate equipment and training to further enable uniform ties to the National Spatial Reference System (NSRS) in Louisiana.
LSU C4G Real-Time Network (RTN) presently consists of over one hundred CORS distributed throughout the state that allow RTN subscribers to login and start working anywhere in the state of Louisiana. C4G RTN subscribers can also subscribe to a post processing service that has access to 1 second RINEX data from any or the CORS in the network and the ability to create Virtual Reference Stations anywhere in the state and generate RINEX files on the fly for these locations. C4G RTN has deployed the infrastructure to support the GLONASS satellite system and members can currently access GLONASS subnets anywhere in the state of Louisiana.

All subscribers will receive the same benefits and must agree to our TERMS OF SERVICE. Academic users must pursue research collaborative agreements with LSU C4G or a memo of understanding from the LSU College of Engineering.
In an effort to deliver the most robust Real Time Network end user experience, C4G has implemented a redundant system of Global Load Balancers that automatically switch RTN users over to the equipment providing the best quality of service. C4G has maintained primary and backup servers for years but end users have always had to switch the hostname manually in their rover settings. With the new Always On redundant global load balancing system a rover simply needs to set the RTN hostname to RTN.LSU.EDU and the LSU DNS servers will direct the connection to the primary or secondary global load balancer based on weighting and availability. The global load balancers continuously monitor the quality of service at the NTRIP servers and pass the rover off to the primary or secondary NTRIP server based on quality of service and availability. The RTN Always On system is currently online and C4G encourages all clients that want to take advantage of this new improved fail-over feature to switch their host address from 22.214.171.124 to RTN.LSU.EDU to take advantage of the robustness of C4GNet's Always On RTN
C4Gnet remained online during Hurricane Isaac but eleven CORS sites went offline for the most part due to power outages in the wake of the storm. C4G will be working to get all of these sites back online as soon as possible. While network solutions are still possible in Southeast Louisiana, extra care should be taken do checks on important points until the network density is restored in this area.
