How to Connect to RTKdata in New Hampshire
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 on a granite quarry in Concord, a ski lift alignment at Cannon Mountain, or a bridge deck survey on the Kancamagus Highway before committing.
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 New Hampshire job sites, expect centimeter-level positioning within seconds.
Why New Hampshire 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 White Mountain valleys, seacoast tidal flats, and southern New Hampshire suburban corridors near the Massachusetts border.
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 Manchester, Nashua, Concord, Portsmouth, Keene, Lebanon, and the White Mountain region. Neighboring states Vermont, Maine, and Massachusetts share the same network.
Industries Using RTK Corrections in New Hampshire
From granite quarry grading to ski resort construction, professionals across the state rely on centimeter-level positioning for diverse terrain and industries.
Granite Quarry Extraction and Monument Grading
The Granite State produces dimensional stone from quarries in Concord, Milford, and Conway. RTK positioning guides drill-hole placement, bench grading, and volumetric stockpile surveys. Centimeter accuracy ensures cut faces meet architectural specifications for building facades and memorial monuments. NH Geological Survey
Ski Resort Lift Alignment and Snowmaking Infrastructure
Cannon Mountain, Loon Mountain, and Bretton Woods rely on precisely graded terrain for lift tower foundations, snowmaking pipe routes, and trail widening. RTK corrections position excavation equipment on steep alpine slopes where traditional survey methods lose efficiency. Ski NH
NHDOT Bridge Rehabilitation and Highway Monitoring
New Hampshire maintains over 2,100 state bridges, many crossing the Connecticut and Merrimack rivers. NHDOT's Ten-Year Transportation Plan funds deck replacements, bearing upgrades, and scour monitoring. RTK-equipped total stations and rovers deliver the structural positioning accuracy these projects demand. NHDOT
Southern Corridor Tech Campus Site Development
The I-93 and Route 101 corridors from Nashua to Manchester attract data centers, biotech labs, and semiconductor facilities. Site grading, utility trenching, and foundation staking for these campuses require centimeter-level machine control from initial earthwork through final as-built surveys. NH Business Review
Maple Syrup Operation and Sugarbush Terrain Mapping
New Hampshire ranks fourth nationally in maple syrup production. Producers map sugarbush terrain with RTK-enabled GNSS to plan tubing networks, gravity-fed collection lines, and access road grading across hillside woodlots. Accurate elevation models reduce sap loss and pumping costs. NH Maple Producers Association
Dam Safety Inspection and Spillway Surveys
New Hampshire's Dam Bureau oversees 435 regulated dams statewide. Safety inspections require precise crest elevation measurements, spillway geometry surveys, and downstream inundation modeling. RTK positioning provides the geodetic control needed for structural deformation monitoring between inspection cycles. ASDSO

Frequently Asked Questions
What is the most reliable RTK service available in New Hampshire?
Do I need my own base station to get RTK corrections in New Hampshire?
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 New Hampshire?
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 New Hampshire's mountainous terrain?
Expect 1-2 cm horizontal and 2-3 cm vertical accuracy in open-sky conditions. White Mountain valleys and dense forest canopy can reduce satellite visibility; plan fieldwork for ridgelines and cleared areas when working in steep terrain.
How does RTKdata compare to the NHDOT CORS network?
NHDOT operates a limited CORS network primarily for department use. RTKdata provides unrestricted access to a broader station network starting at $40 per month with instant self-service activation.
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 systems does RTKdata support in New Hampshire?
Corrections reference NAD83(2011), Epoch 2010.0. Your field software converts to New Hampshire State Plane (NAD83) or UTM Zone 19N.
