RTK corrections in Alaska
RTK Premium delivers RTK corrections in Alaska in NAD83(2011), epoch 2010.0, over standard NTRIP. RTK Premium serves the best solution available at each site: a network (VRS) solution where one exists, and corrections from the nearest reference station where none does, and on the nearest-base stream accuracy depends on the distance to that station. It reaches parts of Southcentral, Interior and Southeast Alaska on 1 network, and most of the state has no RTK Premium network today, so check each site on the coverage map. It costs $900 per device per year, or $690 for RTK Core, and a 14-day free trial comes first.

Elsewhere most of the state has no network, including the North Slope and most of western and northern Alaska; check your site on the map |
|---|---|
| Frame | NAD83(2011), epoch 2010.0; ITRF on request |
| Accuracy | Under 1.5 cm horizontal, 2.5 cm vertical, in a fixed solution on network RTK; on the nearest-base stream, accuracy depends on the distance to the reference station |

Setup guides
More than 100 step-by-step guides cover receivers, controllers, drones and machine control.
Test it yourself
RTKTEST.com compares up to three correction services against a surveyed point in one 15-minute session, and the 14-day trial runs on your own receiver at your own sites.
Correction services in Alaska
Alaska crews choose between the state's reference network, commercial network RTK, crowd-sourced base stations, satellite-delivered corrections and their own base.
| Type | Typical operator | What to check |
|---|---|---|
| State reference network | The state natural resources department with the state DOT and other partners. | Whether it reaches your sites, how you get access, whether an availability commitment is published, and support hours. |
| 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(2011), epoch 2010.0, on every Alaska connection, and ITRF on request. Alaska uses ten State Plane zones under NAD83, and together they use all three State Plane projections: oblique Mercator in zone 1, transverse Mercator in zones 2 to 9 and Lambert conformal conic in zone 10. Set the project, the controller and the correction service to the same frame and zone before the job starts.
Setup
- Start the 14-day free trial on this site, or order a subscription. Your account arrives by email within two working hours.
- Enter the caster rtkpremium.xyz, port 2101 and mountpoint COMMON in your controller or receiver, with the username and password from your account.
- Measure a control point you trust before the job starts, and compare the result with its published coordinates in your project's frame.
Industries using precise positioning or RTK corrections in Alaska
Crude oil: Alaska produced 154,033 thousand barrels of crude oil in 2025, 151,238 thousand of them on the North Slope and 2,795 thousand in South Alaska. Drill pads, pipelines and gravel roads on those fields are surveyed and staked against design. (U.S. Energy Information Administration, Crude Oil Production, 2025)
Seafood: Fishermen landed 4,788,014 thousand pounds of seafood in Alaska in 2024, and the catch was worth $1,368 million. Docks, harbors and processing plants that handle that catch are built and maintained against surveyed control. (NOAA Fisheries, Fisheries of the United States 2024, Table 4, 2024)
Roads: Alaska had 17,654 miles of public road in 2024, 14,282 of them rural, and the state highway agency was responsible for 4,952 rural miles. Grading, culvert work and resurfacing on those roads are staked and checked against design. (FHWA, Highway Statistics, Table HM-10, 2024)
Rural airports: The state DOT maintains and operates 235 airports in its rural aviation system, and 82% of Alaska communities depend on aviation for year-round access. Runway, apron and lighting work at those airports is staked and checked against design. (Alaska DOT&PF, Division of Statewide Aviation, accessed Nov 2026)
Questions about RTK in Alaska
Which RTK correction service serves Alaska?
RTK Premium serves parts of Southcentral, Interior and Southeast Alaska on 1 network with the best solution available at each site, and most of the state has no network today, including the North Slope. The coverage map shows which sites have a network.
Is there a free RTK network in Alaska?
The state natural resources department, working with the state DOT, is building a statewide reference network that it describes as a public service, with a real-time network as its goal. Check whether it reaches your site and what it commits to on availability and support, and check community base stations for distance and survey quality before you rely on them for paid work.
How much does RTK cost in Alaska?
RTK Premium costs $900 per device per year, RTK Core $690 and RTK Access $350, with monthly plans from $39 to $100, excluding sales tax.
Which reference frame and zone do I use in Alaska?
RTK Premium delivers NAD83(2011), epoch 2010.0, with ITRF on request. Alaska has ten State Plane zones under NAD83, so confirm the zone for each site before the job starts.
Do I need my own base station?
Network RTK needs none, because it builds the correction for your position from the surrounding stations. On the nearest-base stream, a site far from the station may do better with a base of its own, so measure a known point near the site first.
How does RTK Premium choose the correction in Alaska?
RTK Premium serves the best solution available at each site: a network (VRS) solution where one exists, and corrections from the nearest reference station where none does. On the nearest-base stream, accuracy falls with distance from the station, and a site on 1 network has no second network to fall back to, so measure a known point near the site before the job starts.
Can I try it before I buy?
Yes. The 14-day free trial runs on your own receiver and needs no payment.
