FPRN (Florida Permanent Reference Network) is Florida's GNSS (Global Navigation Satellite System) Reference Station Network. The FDOT Permanent Reference Network (FPRN) serves as an augmentation service to the public by providing raw GNSS data collected at reference stations across the state. The core of the FPRN is an array of 100 or more continuously operating, dual-frequency geodetic GNSS receivers. Each receiver will log raw GNSS data and transmit it to the Network Operations Center (NOC) in real time via a high-speed data network. The FPRN Operations Center will process the data from each station daily and perform system-wide integrity monitoring. By monitoring the system's integrity in real time, early detection of unhealthy stations can be achieved and corrected.
The I.P. address that you will need to enter into your receiver to connect to the FPRN is 48.223.232.215. The port assignments can be determined from https://www.myfloridagps.com/links/2025products.pdf page. Registration Process for using the FPRN
Currently there are no plans to charge users for any FPRN services or products.
Anyone with an NTRIP ready GPS/GNSS Receiver. Access to the Internet is required. There are no other equipment restrictions or requirements.

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 you respond to the validation email your account will automatically activate. You will receive a confirmation email containing your username. This login is your gateway to the full suite of FPRN services including real-time corrections and other services offered by the FPRN.
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.
We are an email or phone call away. We will make every attempt to assist with the configuration of your rover. https://www.myfloridagps.com/links/support.pdf

Network Transmission of RTCM via Internet Protocol (NTRIP) is the method for delivering GNSS corrections over the internet. Standard formats include: CMR Compact Measurement Record CMR+ Compact Measurement Record Plus RTCM 2.x Radio Technical Commission for Maritime Services version 2.x RTCM 3.x Radio Technical Commission for Maritime Services version 3.x RTCM 3.x MSM 4 Radio Technical Commission for Maritime Services version 3.x Multiple Signal Messages (contains full GNSS Pseudoranges and PhaseRanges plus carrier-to-noise ratio)
SINGLE BASELINE (SBL): Single baseline RTK refers to an RTK configuration where a rover receives correction data from a single physical base station located at a known position.
NETWORK RTK (NRTK): Network RTK integrates data from multiple continuously operating reference stations (CORS) spread throughout the State. By leveraging this network, spatially correlated errors (such as those caused by atmospheric delays, satellite orbits, and clock errors) are modeled collectively, and corrections are interpolated precisely based on the user’s real-time location.
SINGLE BASELINE (SBL): Single baseline RTK refers to an RTK configuration where a rover receives correction data from a single physical base station located at a known position.
AUTOMATIC NEAREST (NEAR): Single Baseline solution to the nearest FPRN Tower
FLACHEN-KORREKTUR-PARAMETER (FKP): a one-way correction method that uses a single set of coefficients transmitted by a base station network to correct a rover's location across a broad area, simplifying correction delivery.
INDIVIDUALIZED MASTER AUXILLARY CONCEPT (iMAX): The network uses multiple stations to model atmospheric and other errors and then sends a "personalized" correction stream to the rover that is referenced to a master station.
AUTOMATIC INDIVIDUALIZED MASTER AUXILLARY CONCEPT (AUTO-iMAX): The network determines the distance from the closest station and sends a correction stream to the rover. If the distance is under 14 kilometers, an SBL solution is sent; otherwise, an iMAX solution is sent.
VIRTUAL REFERENCE STATION (VRS): uses a network of fixed reference stations to create a virtual one at your specific location, providing real-time, centimeter-level accuracy without the need for a physical base station.
AUTOMATIC VIRTUAL REFERENCE STATION (AUTO-VRS): The network determines the distance from the closest station and sends a correction stream to the rover. If the distance is under 14 kilometers, a SBL solution is sent; otherwise, a VRS solution is sent.
RINEX Download: Users can download static RINEX data for each FPRN Station.
Computation Service: Users can submit Rover Rinex data for positioning computation.
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 GNSS 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.
North American Datum of 1983 - NAD83 (2011) (Epoch 2010.0000): The horizontal and geometric datum for North America.
North American Reference Frame of 2022 - NATRF2022 (Epoch 2020.0000): a new and modernized geodetic reference system replacing NAD83.
World Geodetic System 1984 – WGS84 (G2296): defines an Earth-centered, Earth-fixed coordinate system and a geodetic datum, and also describes the associated Earth Gravitational Model (EGM) and World Magnetic Model (WMM).
International Terrestrial Reference Frame 2020 – ITRF2020: a system that provides a standardized set of 3D coordinates for locations on Earth. Epoch is updated quarterly.
