RTK corrections in Hawaii
RTK Premium delivers network RTK corrections in Hawaii in NAD83(PA11), epoch 2010.0, over standard NTRIP. In a fixed solution it reaches under 1.5 cm horizontally and 2.5 cm vertically. The coverage map shows 1 network on Hawaii Island, Maui, Oahu, Molokai and Lanai, and no network on Kauai and Niihau today, and a site on 1 network has no second network to fall back to if that network drops. It costs $900 per device per year, or $690 for RTK Core, and a 14-day free trial comes first.

Correction services in Hawaii
Hawaii crews choose between commercial network RTK, crowd-sourced base stations, satellite-delivered corrections and their own base.
| Type | Typical operator | What to check |
|---|---|---|
| Commercial network RTK | A private provider with stations across several states. | How many correction sources serve your area, the published service level and its remedy, and the term. |
| Crowd-sourced network | Independent owners hosting single base stations. | Distance to the nearest base, station uptime, and how each base was surveyed. |
| Satellite or state-space (PPP-RTK, SSR) | A provider broadcasting an error model without a local base. | Convergence time, accuracy and vertical performance. |
| Your own base | Your crew, on a surveyed point. | The survey of the base point, range, and the time spent setting it up and guarding it. |
Coordinates and heights
RTK Premium delivers NAD83(PA11), epoch 2010.0, on every Hawaii connection, and ITRF on request. NAD83(PA11) is the Pacific realization of NAD83 and differs from the NAD83(2011) frame used on the mainland, so set Hawaii projects and controllers to NAD83(PA11). Hawaii uses five State Plane zones under NAD83, Zone 1 to Zone 5, each on a transverse Mercator projection. NAVD 88 does not extend to Hawaii, so check the height datum each project specifies. Set the project, the controller and the correction service to the same frame and zone before the job starts.

Industries using precise positioning or RTK corrections in Hawaii
Farmland: Hawaii had 6,500 farm operations on 1,050,000 acres operated in 2025. Planting, irrigation and spraying on those farms, much of it on sloping ground, depend on a correction that holds pass after pass. (USDA NASS, State Agriculture Overview, 2025)
Coffee and macadamias: Hawaii's utilized coffee crop reached 4,910,000 pounds on a parchment basis in 2025, and its macadamia crop reached 30,600,000 pounds in shell. Orchard blocks are mapped so that planting, drainage and harvest follow the same rows each season. (USDA NASS, State Agriculture Overview, 2025)
Roads: Hawaii had 4,628 miles of public road in 2024, 3,246 of them urban. Resurfacing, widening and drainage on those roads are staked and checked against design. (FHWA, Highway Statistics, Table HM-10, 2024)
Power plants: Hawaii's power plants had a net summer capacity of 3,369 megawatts in 2024, and petroleum was the primary energy source. Solar farms, substations and transmission routes are laid out from surveyed points. (U.S. Energy Information Administration, 2024)
