FPRN Frequently Asked Questions

The I.P. address that you will need to enter into your receiver to connect to the FPRN is 40.121.5.206. The port assignments can be determined from https://www.myfloridagps.com/Products/Nad83.pdf page.

FPRN (Florida Permanent Reference Network) is Florida's GNSS (Global Navigation Satellite System) Reference Station Network. The FDOT Permanent Reference Network (FPRN) will serve as an augmentation service to the survey engineering community by providing raw GPS data collected at reference stations statewide. The core of this project is an array of 100 or more continuously operating, dual-frequency geodetic GPS sensors. Each sensor will log raw GPS data and transmit this data to the Network Operations Center (NOC) in real time via hi-speed data network. The FPRN Operations Center will process the data from each station daily and perform system wide integrity monitoring. By monitoring the systems integrity (in real time) early detection of unhealthy stations can be detected and corrected.

Currently there are no plans to charge users for any FPRN services or products.

Anyone with a NTRIP ready GPS/GNSS Receiver. Access to the Internet is required. There are no other equipment restrictions or requirements.

Please visit the FPRN Terms of Use page for terms and conditions.

You will need to create a separate account for each rover. Please visit the FPRN Registration page and complete a separate registration form for each rover. Once completed, we will activate your account within 24-48 hours. You will receive an email containing your FPRN username and password. This login is your gateway to the full suite of FPRN services including both real-time corrections and RINEX data files.

You will need to create a separate account for each rover. Please visit https://www.myfloridagps.com/sbc to either make changes to your existing account information by logging in, or to create new user accounts by selecting “create new account” in the upper right hand corner of the login page before entering your credentials

We are an email or phone call away. We will make every attempt to assist with the configuration of your rover. The FPRN Help page has multiple articles on configuration.

Please visit the FPRN page for additional information!.

Standard formats include:

Absolutely NOT! We go out of our way to provide corrections to ANY sensor that has the means to receive RTN data, regardless of brand or age.

Assuming the standard GPS RTK protocols and best practice methods are employed for maximum precision i.e. good satellite coverage, good geometry of precisions, low multi path environments etc., FPRN typically achieves an RTK accuracy of 1-2 cm horizontally and 2-3 cm height.

The FDOT maintains and publishes universal coordinates (geocentric polar and Cartesian) for the Florida Permanent Reference Network (FPRN) as we must deal with one coordinate system for the entire state. We leave it up to the end user to translate our universal coordinates into whichever State Plane (SP), Universal Transverse Mercator (UTM), or other projection that is appropriate for his or her use. Today, virtually all vendor-supplied GPS processor packages come with projection translators that can be tailored to one’s particular needs. The National Geodetic Survey (NGS) also makes available translators at their web site for producing state plane coordinates from geocentric coordinates such as those published for the FPRN.

The old and new FPRN geocentric coordinates are based on the same ellipsoid which is GRS1980. This is the ellipsoid on which all North America Datum of 1983 (NAD83) coordinates are based. Therefore you can use the same projection translator for the old and new FPRN universal coordinates for your comparison at specific locations. The FDOT does not have the resources to provide specific projection comparisons for specific sites as each site (be it FPRN station or other control) can have multiple projection coordinates associated with it. We leave that exercise of producing projected plane coordinates up to the end user.
