Reference Stations

Florida Permanent Reference Network
The Florida Permanent Reference Network (FPRN) is an RTK GPS network presently consisting of nearly 100 Continuously Operating Reference Stations in Florida built and operated by the Florida Department of Transportation, or its cooperative agencies.

The network presently provides RTK baseline solutions to public and private users free of charge as a public resource to the taxpayers of the State of Florida, regardless of which brand of GPS equipment they use. Access is provided through off-the-shelf cellular modems connecting to the internet. IP/Port assignments for each reference station are available on

The system utilizes Leica Geosystems GPS Reference Stations controlled by Leica SPIDER Reference Station software. Plans call for additional reference stations to be added over time, and for the inclusion of correction data from existing private and public reference station networks, thus creating a densely populated system capable of providing network solutions statewide.
