What is FPRN?

   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.

Is there a fee for using the network?

   Currently there are no plans to charge users for access to the real-time network.

Who can use it?

   Anyone with a network ready GPS receiver. All corrections are available thru the internet via NTRIP and TCP/IP protocols. So whether you own a Leica Geosystems rover or another make of GPS receiver you are able to gain access to the service via mobile phone technology..

What are the Network Terms of Use?

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

What type of cell phone do you need and what provider should I use?

   Data services are available through most of the major carriers in Florida. GPRS/EDGE (T-Mobile and AT&T) or CDMA (Verizon) services can be used. Please select the carrier that provides the most reliable coverage for your planned area of operation. In addition to manufacturer specific cellular devices, standard cellular phones or cellular modems may also be used. To use a standard cell phone, please verify it has Bluetooth Dial-Up Networking or Wi-Fi capabilities and a data plan that is capable of "tethering".

How do I get access to the network?

   Please visit the FPRN Registration page and complete the registration form. 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.

How can I add additional rovers or make changes to my account?

   Re-visit the FPRN Registration page and enter the username and password you were supplied. You can add additional rovers, change contact information, etc.


How do I get support for my rover?

   We are an email or phone call away. We will make every attempt to assist with the configuration of your rover. The FPRN Contacts page has multiple articles on configuration. This site is independent of the primary FPRN portal. You will need to register an account. For continuity, use you existing account credentials.


Where can I find out more information about FPRN?

   Please visit the FPRN page for additional information!.


Is there a fee for using the network?

   Currently there are no plans to charge users for access to the real-time network.


What correction formats are available?

   Standard formats include:
     SINGLE BASELINE: RTCM 2.3,RTCM 3.1, CMR+ and Leica
     VRS:RTCM 2.3, RTCM 3.1, CMR+ and Leica
     MAX/iMAX:RTCM 2.3, RTCM 3.1, CMR+ and Leica.


Does the FPRN limit support of GPS rovers?

   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.


Where can I get connection information?

   New connection information for your particular rover and a complete list of all real time products will be available soon. Contact FPRN support staff for more information.


What is the RTK (Real Time Kinematic) accuracy?

   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 multipath environments etc, FPRN typically achieves an RTK accuracy of 1-2 cm horizontally and 2-3 cm height.


What is the established datum for FPRN?

   FPRN is on NAD(83)-(CORS96)-(Epoch 2002.0000).


Where can I get a map of the stations?

   You can always visit www.http://www.dot.state.fl.us/surveyingandmapping/fprn.shtm for more information.
