How to Connect to RTKdata in South Carolina
Works with Trimble, Leica, Topcon, Emlid, u-blox, Septentrio, and any RTCM v3 receiver.
01
Choose a Plan
Pick a subscription that fits your workload or start with the free 30-day trial. Test corrections across your project sites before committing to a paid plan.
02
Enter NTRIP Credentials
Add the server address, port, and mountpoint we provide into your rover or field controller. Setup takes a few minutes regardless of hardware brand.
03
Verify FIX
Power on your receiver and confirm a fixed RTK solution. In typical open-sky conditions across Lowcountry marshlands or Upstate construction sites, expect centimeter-level positioning within seconds.
Why South Carolina professionals choose RTKdata
Accuracy
1-2 cm horizontal, 2-3 cm vertical in open sky. Multi-constellation RTCM 3.x corrections via NTRIP keep your rover on target across humid Lowcountry coastlines, Piedmont clay soils, and Blue Ridge mountain terrain.
Speed
RTK FIX in seconds statewide. Single NTRIP mount point with no manual base switching. Surveyors and machine control operators stay productive from the first setup.
Availability
99.99% NTRIP endpoint uptime (rolling 12 months). Monitored 24/7 for consistent real-time streams across all conditions.
Coverage
RTK stations across Charleston, Columbia, Greenville, Spartanburg, Myrtle Beach, and Hilton Head. Neighboring states North Carolina and Georgia share the same network.
Industries Using RTK Corrections in South Carolina
South Carolina’s deepwater port expansion, military installations, BMW manufacturing campus, booming Lowcountry construction, and 187 miles of Atlantic coastline drive centimeter-level RTK demand across all 46 counties.
Military Installation Construction at Joint Base Charleston and Fort Jackson
South Carolina hosts eight major military installations including Joint Base Charleston, Fort Jackson (the Army's largest initial entry training center), Shaw AFB, and Marine Corps Recruit Depot Parris Island. RTK supports facility construction, runway surveys, range modernization, and utility infrastructure across these bases, with combined annual military construction budgets exceeding $500 million.
Automotive Manufacturing
BMW Plant Spartanburg is the largest BMW factory globally, producing over 1,500 vehicles per day across a 1,150-acre campus (BMW Group). Machine guidance, site grading, and facility expansion surveys demand centimeter-level precision.
Port and Maritime Construction
The Port of Charleston's Hugh Leatherman Terminal expansion adds 1,600 feet of new wharf and five ship-to-shore cranes (SC Ports). Dredging, pile driving, and berth alignment surveys require continuous RTK corrections.
Coastal Engineering and Beach Renourishment
The $72M Grand Strand renourishment places 2 million cubic yards of sand along 26 miles of coastline (USACE Charleston District). Hilton Head's $47.5M project covers 46,500 feet of shoreline (Beaufort County). RTK-guided dredges ensure precise sand placement.
Precision Agriculture and Peach Farming
South Carolina is the second-largest peach-producing state, harvesting 67,400 tons annually (USDA ERS). RTK auto-steer enables sub-inch row guidance for Ridge region orchards and Pee Dee row crops.
SCDOT Carolina Crossroads and Interstate Widening
SCDOT manages nearly $7 billion in active projects including the $2.75B Carolina Crossroads interchange and I-95 widening (SCDOT). Machine control on graders, excavators, and pavers relies on continuous RTK corrections for grade accuracy.

Frequently Asked Questions
What is the most reliable RTK service available in South Carolina?
Do I need my own base station to get RTK corrections in South Carolina?
No. RTKdata streams network RTK corrections from continuously operating reference stations. Your rover connects via NTRIP and receives real-time RTCM3 data without a local base.
Which GNSS receivers work with RTKdata in South Carolina?
Any device supporting RTCM v3 over NTRIP connects without modification. This includes equipment from Trimble, Leica, Topcon, Emlid, u-blox, and Septentrio.
How accurate is RTK positioning in coastal South Carolina conditions?
Expect 1-2 cm horizontal and 2-3 cm vertical accuracy in open-sky conditions. Dense base station spacing compensates for tropospheric delays common in Lowcountry humidity and subtropical storm systems.
How does RTKdata compare to the SC VRS network?
Can I test RTKdata before subscribing?
Yes. The 30-day free trial includes full access to all corrections and features. No credit card is required and the trial ends automatically.
Which coordinate system does RTKdata support in South Carolina?
Corrections reference NAD83(2011), Epoch 2010.0. Your field software converts to South Carolina State Plane (single zone, FIPS 3900, Lambert Conformal Conic) or UTM.
Experience precise RTK coverage across South Carolina
From port expansion surveys in Charleston to beach renourishment along the Grand Strand, RTKdata provides GNSS corrections that keep your positioning within centimeters. Connect your receiver via NTRIP and reach a fixed solution in seconds.
