Choose a Plan

Pick a monthly or annual subscription, or start with the free 30-day trial. Test corrections at your Missouri project sites — a levee alignment along the Missouri River, a lead mine bench in the Viburnum Trend, or a soybean field near the Grand River bottoms — before committing.

Enter NTRIP Credentials

Configure the server address, port, and mountpoint in your rover or field controller. Works with Trimble, Leica, Topcon, Emlid, u-blox, and Septentrio receivers.

Verify FIX

Confirm a fixed RTK solution on your device. Missouri’s rolling terrain and open agricultural expanses across the northern plains and Bootheel region provide strong satellite visibility, enabling fast convergence and stable centimeter-level positioning.

Why Missouri professionals choose RTKdata

Accuracy

1-2 cm horizontal, 2-3 cm vertical under open sky. Multi-constellation RTCM 3.x corrections via NTRIP perform reliably across Missouri's diverse topography -- from alluvial floodplains at the Mississippi-Missouri confluence near St. Louis to the forested karst terrain of the Ozark Plateau and open cropland stretching across the northern tier.

Speed

RTK FIX within seconds at any Missouri job site. One NTRIP mount point delivers corrections statewide with no manual base switching. Crews working flood recovery timelines and seasonal planting windows stay productive without equipment resets.

Availability

99.99% NTRIP endpoint uptime over a rolling 12-month period. Monitored around the clock for consistent real-time streams during Missouri's severe spring storms and humid summer conditions.

Coverage

Stations serving Kansas City, St. Louis, Springfield, Columbia, Jefferson City, Joplin, St. Joseph, and Cape Girardeau. Neighboring states Iowa, Illinois, Kentucky, Tennessee, Arkansas, Oklahoma, Kansas, and Nebraska connect through the same network for seamless cross-border corrections.

Industries Using RTK Corrections in Missouri

Missouri sits at the confluence of the two longest rivers in North America, produces more lead than any other state, supports a $14.7 billion agricultural economy, and is investing billions in metro construction across Kansas City and St. Louis.

Mississippi-Missouri River Levee Surveying and Flood Monitoring

Missouri contains more than 1,300 miles of federal levees along the Mississippi and Missouri rivers (MO DNR). RTK-equipped GNSS rovers and UAVs collect levee crest profiles, seepage berm grades, and floodwall alignment data at centimeter accuracy for the Corps' Levee Screening Tool. Pre- and post-flood cross-section comparisons detect settlement and erosion that visual inspection cannot quantify.

Viburnum Trend Underground Lead Mining

Missouri produces approximately 70% of the nation's primary lead supply from the Viburnum Trend (Doe Run). Underground drift surveys, shaft alignment checks, ore body delineation, and surface operations -- haul road grading, tailings impoundment monitoring, and reclamation compliance surveys -- depend on RTK for grade control across hilly, forested terrain.

Kansas City Riverfront and Streetcar Construction

Kansas City's development pipeline includes the $1 billion KC Current riverfront district, the $480 million Scarritt Building transformation, and the $500+ million West Bottoms redevelopment. RTK-guided machine control supports mass grading on riverfront sites and sub-centimeter construction staking for streetcar track alignment and station platforms.

Soybean and Cattle Operation Precision Agriculture

Missouri farms generated $14.7 billion in combined crop and livestock receipts in 2025, with 5.9 million acres of soybeans at a record 53.5 bu/acre yield (Missouri Department of Agriculture). RTK auto-steer directs planting, spraying, and harvest passes across the northern plains and Bootheel alluvial soils. RTK-guided fence line surveys and stock pond construction serve cattle operations in the Ozark foothills.

MoDOT River Bridge Replacement and Interstate Widening

MoDOT is investing $1.7 billion in St. Louis alone, with the $600+ million Improve I-70 Project widening from Warrenton to Wentzville. Missouri maintains 24,478 bridges -- fourth most of any state. Network RTK delivers corrections to bridge deck profiling equipment and mobile LiDAR platforms without requiring a physical base station near waterways.

NGA Next NGA West Campus and Geospatial Corridor

The $1.7 billion Next NGA West campus opened in north St. Louis in September 2025 with a 700,000 sq ft office building and 3,150-person workforce. RTK supports site grading, utility installation, perimeter alignment, and as-built documentation on the campus and neighboring GeoFutures district redevelopment parcels.

Last updated: March 30, 2026. Competitor pricing verified from provider websites where available. MoDOT RTN station count from gpsweb3.modot.mo.gov. MoDOT operates the Missouri Real Time Network with 78 GNSS reference stations (NetR5 receivers with Zephyr Geodetic II antennas) spaced at a maximum of 70 km. The network tracks GPS and GLONASS and is built to NGS CORS specifications. Data is available at no charge to registered users via NTRIP. Point One Polaris and Skylark offer hardware-agnostic corrections at a national scale. Trimble VRS Now and Leica SmartNet deliver strong performance within their respective hardware ecosystems.

Frequently Asked Questions

Which RTK correction service covers all of Missouri including rural counties?

RTKdata delivers NTRIP corrections across all 114 Missouri counties and St. Louis City with 99.99% endpoint uptime. The network reaches from the Bootheel to the Iowa border and from the Kansas City metro to the Mississippi River. Subscriptions start at $40 per month with a 30-day free trial that ends automatically.

How does the MoDOT Real Time Network compare to RTKdata?

MoDOT operates 78 CORS stations across the state with free public access via NTRIP registration. RTKdata provides access to a larger global network of 20,000+ stations, instant self-service activation, a 99.99% uptime SLA, multi-constellation support (GPS, GLONASS, Galileo, BeiDou), and cross-state coverage into all eight bordering states — starting at $40 per month.

Can RTKdata support levee surveys along the Mississippi and Missouri rivers?

Yes. RTK corrections provide centimeter accuracy for levee crest profiling, cross-section surveys, seepage berm grading, and floodwall alignment checks. Network RTK eliminates the need to place a base station on unstable floodplain ground near the riverbank, and corrections remain available during and after flood events when physical access is limited.

Does Missouri's terrain affect RTK correction accuracy?

The open cropland of northern Missouri and the Bootheel provides strong satellite visibility for fast RTK convergence. The forested Ozark Plateau may reduce satellite count under dense canopy, but multi-constellation processing (GPS, GLONASS, Galileo, BeiDou) maintains reliable fixes in most open-sky clearings, ridgetops, and road corridors.

What GNSS equipment connects to RTKdata in Missouri?

Any receiver that accepts RTCM v3 corrections over NTRIP works without modification. Trimble, Leica, Topcon, Emlid, u-blox, and Septentrio equipment all connect. This includes rovers on MoDOT highway projects, auto-steer tractors in soybean fields, and UAV payloads mapping mine sites in the Viburnum Trend.

Does RTKdata support MoDOT highway and bridge survey standards?

Corrections reference NAD83(2011), consistent with MoDOT survey control requirements. RTK provides centimeter accuracy for construction staking, earthwork measurement, bridge deck profiling, and mobile LiDAR control on state highway and interstate projects.

What coordinate systems does RTKdata support for Missouri surveys?

Corrections reference NAD83(2011). Missouri uses three State Plane zones: East (FIPS 2401), Central (FIPS 2402), and West (FIPS 2403), all on the Transverse Mercator projection in U.S. Survey Feet. Most of the state falls in UTM Zone 15N, with eastern counties extending into UTM Zone 16N. Kansas City is in the West zone. St. Louis is in the East zone.

Reach centimeter accuracy on every Missouri job site

From levee surveys along the Mississippi-Missouri confluence to underground lead mine control in the Viburnum Trend and soybean fields spanning the northern plains, RTKdata delivers centimeter-level GNSS corrections across all 114 counties.
