C4G launched it's RTN (Real Time Network) in November of 2007, with the intention of bringing National Spatial Reference System (NSRS) positions to users in Real-Time. The C4G RTN started out as GPS only and quickly expanded to include GLONASS and in 2008 C4G had 42 CORS deployed throughout Louisiana. All servers were hosted at LSU C4G and the infrastructure hardware and software quickly increased by 4 times what it was in 2008. 

It became clear that to provide our clients with 24/7 top-tier Quality of Service, C4G needed to move its mission-critical servers off-campus to a top-tier hosting facility to give our clients availability that was never possible on the LSU network. Non-critical servers are still at LSU C4G so we currently manage hardware and software at both LSU and our off-campus hosting facility.  

The C4G RTN became C4Gnet.XYZ in January of 2018 with too many important advancements bundled into it to get into here, but the verbose details of all the tools and features is available in the C4Gnet.XYZ RTN User Guide found on the C4Gnet.XYZ portal.  

Our core servers and software have undergone major upgrades, essentially operating on a totally new platform. Now that the C4Gnet.XYZ has gone through this expansion phase there are over 130 stations in the RTN and statewide coverage with GPS, GLONASS, Galileo and BeiDou constellations being supported so we are concentrating on outreach to help users understand the benefits of the many new features and services C4Gnet.XYZ provides.

C4Gnet.XYZ has coverage for the entire State of Louisiana.  

C4Gnet.XYZ Constellation Upgrades 

All C4Gnet.XYZ stations support GPS, GLONASS, Galileo and BeiDou constellations, we continue to replace all our older receivers with the latest GNSS capable receivers. We currently support all constellations and signals including L2C and L5. If you wish to access all constellations, you will want to use a mountpoint that includes GREC in its name.
