How to Connect to RTKdata in Hawaii
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 local job sites, expect centimeter-level positioning within seconds.
Why Hawaii professionals choose RTKdata
Accuracy
1-2 cm horizontal, 2-3 cm vertical in open sky. Multi-constellation RTCM 3.x corrections via NTRIP compensate for tropical atmospheric conditions and varying elevation from sea level to 13,796 ft on Mauna Kea.
Speed
RTK FIX in seconds across all islands. 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 Honolulu, Hilo, Kailua-Kona, Kahului, Lihue, and Pearl City. Coverage spans all major inhabited islands in the archipelago.
Industries Using RTK Corrections in Hawaii
From volcanic deformation research to resort construction, professionals across the islands rely on centimeter-level positioning for unique terrain and industries.
Volcanic Terrain Deformation Monitoring
The USGS Hawaiian Volcano Observatory tracks ground deformation at Kilauea and Mauna Loa using continuous GNSS stations. RTK corrections enable researchers to detect centimeter-scale uplift and subsidence patterns that signal magma movement beneath active shield volcanoes.
Macadamia Nut and Coffee Precision Farming
Hawaii produces 100% of U.S. commercial macadamia nuts and the only domestic Kona coffee crop (USDA NASS). RTK-guided variable-rate fertilization and orchard mapping on steep volcanic slopes optimize yields while minimizing input costs on limited arable land.
Military Installation Construction and Modernization
Pearl Harbor Naval Shipyard, Schofield Barracks, and Marine Corps Base Hawaii support continuous construction and infrastructure modernization. RTK positioning delivers centimeter staking accuracy for barracks, hangars, and port facility upgrades across Oahu's military installations (NAVFAC).
Resort and Hospitality Development
Hawaii's tourism-driven economy fuels ongoing hotel and resort construction across Waikiki, Maui's Wailea coast, and the Kohala Coast. RTK corrections support site grading, foundation staking, and landscape contouring on coastal parcels where elevation precision is critical for flood zone compliance (DBEDT).
Coral Reef and Nearshore Bathymetric Survey
NOAA and state DLNR teams map coral reef extent and health across the archipelago using RTK-corrected survey-grade GNSS. Precise tidal benchmarks and nearshore bathymetry support reef restoration planning and sediment transport studies in one of the world's most biodiverse marine ecosystems (NOAA CRCP).
HDOT Inter-Island Bridge and Highway Infrastructure
The Hawaii Department of Transportation maintains highways, bridges, and harbor facilities across six inhabited islands. RTK positioning supports slope stability monitoring on mountain passes, bridge inspection surveys, and highway reconstruction projects like the Saddle Road realignment on the Big Island.

Frequently Asked Questions
What is the most reliable RTK service available in Hawaii?
Do I need my own base station to get RTK corrections in Hawaii?
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 Hawaii?
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 across Hawaii's volcanic terrain?
Expect 1-2 cm horizontal and 2-3 cm vertical accuracy in open-sky conditions. Hawaii’s tropical atmosphere and varying elevation from sea level to 13,796 ft on Mauna Kea require multi-constellation corrections that RTKdata provides.
Does RTKdata cover all Hawaiian islands?
Yes. RTKdata provides RTK corrections across all major inhabited islands including Oahu, Maui, the Big Island (Hawaii), Kauai, Molokai, and Lanai via the same NTRIP subscription.
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 Hawaii?
Corrections reference NAD83(2011), Epoch 2010.0. Your field software converts to the appropriate Hawaii State Plane zone (Zone 1 through Zone 5) or UTM Zone 4N/5N.
Experience precise RTK coverage across Hawaii
From volcanic deformation monitoring on the Big Island to resort construction surveys along the Kohala Coast, RTKdata provides GNSS corrections that keep your positioning within centimeters. Connect your receiver via NTRIP and reach a fixed solution in seconds.
