How to Connect to RTKdata in Oklahoma
Works with Trimble, Leica, Topcon, Emlid, u-blox, Septentrio, and any RTCM v3 receiver.
01
Choose a Plan
Pick a monthly or annual subscription, or start with the free 30-day trial. Test corrections on your Oklahoma job sites — a wind turbine foundation pour near Weatherford, a tribal boundary survey in Muskogee County, or a pipeline alignment at the Cushing hub — before committing.
02
Enter NTRIP Credentials
Add the server address, port, and mountpoint to your rover or field controller. Compatible with Trimble, Leica, Topcon, Emlid, u-blox, and Septentrio receivers.
03
Verify FIX
Confirm a fixed RTK solution on your device. Oklahoma’s open prairie terrain and minimal tree canopy across most of the state provide excellent satellite visibility and rapid convergence to centimeter-level accuracy.
Why Oklahoma professionals choose RTKdata
Accuracy
1-2 cm horizontal, 2-3 cm vertical under open sky. Multi-constellation RTCM 3.x corrections via NTRIP perform across Oklahoma's varied terrain -- from the flat Panhandle wheat fields and rolling Cross Timbers to the Ouachita Mountains and Red River floodplain in the south.
Speed
RTK FIX within seconds at any Oklahoma project site. A single NTRIP mount point delivers corrections statewide with no base switching. Wind farm crews and survey teams maintain productivity across remote western Oklahoma where cellular coverage can be sparse.
Availability
99.99% NTRIP endpoint uptime over a rolling 12-month period. Monitored around the clock for uninterrupted real-time streams during Oklahoma's severe weather season, including supercell thunderstorms and tornado events.
Coverage
Stations serving Oklahoma City, Tulsa, Norman, Broken Arrow, Lawton, Edmond, Stillwater, and Enid. Neighboring states Kansas, Missouri, Arkansas, Colorado, New Mexico, and Texas connect through the same network for seamless cross-border corrections.
Industries Using RTK Corrections in Oklahoma
Oklahoma’s booming wind energy sector, 39 tribal nations with complex land boundaries, Cushing pipeline hub, Tornado Alley damage assessment needs, and wheat and cattle precision agriculture demand centimeter-level RTK accuracy.
Wind Turbine Foundation Layout and Farm Construction
Oklahoma ranks third nationally in installed wind energy capacity with over 12,700 MW across more than 50 operational wind farms (DOE WINDExchange). The 998 MW Traverse Wind Energy Center in Custer and Blaine counties required precise foundation layout for hundreds of turbine pads. RTK-guided grading supports turbine foundations, access road alignment, crane pad leveling, underground collection system trenching, and substation site preparation. Centimeter positioning ensures each turbine pedestal meets the 3 mm levelness tolerance required by major OEMs.
Tribal Land Surveying and Checkerboard Boundary Delineation
Oklahoma is home to 39 federally recognized tribal nations, more than any other state (Oklahoma Tribal Jurisdictions). The McGirt v. Oklahoma (2020) decision reaffirmed tribal sovereignty over much of eastern Oklahoma, intensifying demand for precise boundary surveys on checkerboard trust, allotment, and fee-simple lands. Surveyors reconcile General Land Office section lines with modern geodetic control. RTK provides the centimeter accuracy needed for trust-to-fee conversions, right-of-way acquisitions, and environmental compliance mapping.
Cushing Oil Hub Pipeline Surveys and Tank Farm Monitoring
Cushing is the delivery point for WTI crude oil futures, storing approximately 90 million barrels across 15 terminal complexes -- 13% of total U.S. commercial crude storage (EIA Oklahoma). The hub's two dozen pipelines with over 6.5 million barrels per day of flow capacity require continuous surveying for new pipeline construction, cathodic protection surveys, tank settlement monitoring, and right-of-way maintenance across Payne, Creek, and Lincoln counties.
Tornado Damage Assessment and Storm Response Surveying
Oklahoma averages 56 tornadoes per year in the core of Tornado Alley. The 2024 season produced two EF-4 tornadoes -- Marietta in April and Barnsdall-Bartlesville in May (NWS Norman). Post-storm surveys use rapid-deployment GNSS to document debris fields, map displaced structures for insurance adjusters, and establish new control for rebuilding. RTK-equipped drones generate georeferenced orthomosaics within hours, supporting FEMA preliminary damage assessment.
Wheat Belt and Cattle Ranch Precision Agriculture
Oklahoma ranks second nationally in winter wheat harvest and second in beef cow inventory, with 2.57 million acres of wheat and over 2.77 million acres of forage (USDA NASS). RTK auto-steer enables sub-inch pass-to-pass accuracy for wheat drilling, fertilizer application, and harvest operations from Garfield County through Caddo County. Cattle operations use RTK for fence line surveying, stock pond grading, and rotational grazing paddock layout.
ODOT Highway and Bridge Infrastructure Program
ODOT's FY 2026-2033 Eight-Year Construction Work Plan contains $7.7 billion in highway investments across more than 1,200 projects, including 209 bridge projects and 2,800 miles of pavement improvements (ODOT). Major corridor work includes I-35 widening, the US-70 Roosevelt Bridge replacement over Lake Texoma, and the US-81 Chickasha Bypass. RTK machine control on graders, milling machines, and pavers meets ODOT ride quality specifications.

Frequently Asked Questions
Which RTK service provides real-time corrections across all of Oklahoma?
Does Oklahoma have a free state-operated RTK network?
No. Unlike neighboring Kansas and Missouri, Oklahoma does not operate a state DOT real-time CORS network. NOAA CORS stations within Oklahoma provide RINEX files for post-processing only. RTKdata offers the closest equivalent to a statewide RTK service at $40 per month with instant activation and no hardware restrictions.
Do I need my own base station for RTK in Oklahoma?
No. RTKdata generates network corrections from surrounding reference stations, eliminating the need to transport, set up, and maintain a local base. This applies whether you are surveying a wind farm pad near Woodward or a pipeline right-of-way in Cushing.
How does Oklahoma's open terrain affect RTK accuracy?
Oklahoma’s predominantly flat to rolling prairie provides excellent satellite visibility. Expect 1-2 cm horizontal and 2-3 cm vertical accuracy across most of the state. The Ouachita Mountains in the southeast and wooded Cross Timbers belt may reduce satellite count under canopy, but multi-constellation tracking (GPS, GLONASS, Galileo, BeiDou) maintains fix reliability.
Which GNSS receivers are compatible with RTKdata in Oklahoma?
Any receiver supporting RTCM v3 over NTRIP connects without modification. This includes Trimble, Leica, Topcon, Emlid, u-blox, and Septentrio equipment — whether mounted on a survey rod, a machine control dozer, an auto-steer tractor, or a mapping drone.
What coordinate system does Oklahoma use for land surveys?
Oklahoma uses two State Plane zones — North (FIPS 3501) and South (FIPS 3502) — on the Lambert Conformal Conic projection in US survey feet, referenced to NAD83(2011). The state also spans UTM Zones 14N and 15N. RTKdata corrections are datum-independent and work with any coordinate system configured in your receiver or field software.
Can RTKdata support post-tornado damage assessment in Oklahoma?
Yes. RTK corrections enable rapid-deployment GNSS surveys and drone mapping after severe weather events. Georeferenced orthomosaics produced within hours of a tornado support FEMA preliminary damage assessment, insurance claims documentation, and emergency infrastructure inspection across affected areas.
Centimeter-accurate RTK corrections from the Panhandle to the Ouachitas
From wind turbine foundations on the western plains to tribal boundary surveys in eastern Oklahoma and pipeline alignments at Cushing, RTKdata provides centimeter-level GNSS corrections through a single NTRIP connection.
