Is Alaska or Hawaii covered?

No. Neither Alaska, nor Hawaii, nor the US offshore territories are inside Northing RTK coverage. When this site says "US coverage" it means the contiguous states, and we would rather be blunt about that here than have you find out after paying. The free Northing Global mode works in all of them.

My farm is near the edge of a covered zone. Will it work?

Check rather than assume. Coverage boundaries are polygons, not national borders, and "the county is covered" does not mean the far side of it is. Send us the location — a town is usually enough, coordinates are better near an edge — and you will get a specific answer. Your location is also checked at checkout.

What happens if I am outside coverage?

The receiver still works everywhere on Earth on Northing Global, the free built-in mode, which has no coverage zones because its corrections come from the navigation satellites themselves. Accuracy is 10–20 cm once converged rather than ±2.5 cm, and it takes minutes to settle rather than seconds. We will not sell you an RTK subscription for a location it cannot serve.

Does coverage change?

Yes, and it generally expands. This page is dated at the top for that reason — a stale coverage claim is worse than none. If you were declined once, it is worth rechecking.

Do I need coverage where I bought it, or where I work?

Where you work. The subscription is not locked to a billing address; the check at checkout exists to stop you buying a service that cannot reach your fields. If you work across a boundary, tell us the awkward location, not the convenient one.

Northing RTK coverage, plainly stated

Where the RTK subscription works as of August 2026 — the regions covered, the gaps stated as clearly as the coverage, and what to do if you are outside them.

Coverage maps in this industry are usually a zoomed-out blob that makes everything look covered. Here is Northing RTK coverage in words, as of August 2026 — gaps included, because finding one from the cab is a much worse way to learn about it than reading it here.

The short version: Northing RTK is coverage-bound and Northing Global is not. Every receiver has both.

Covered

These are the regions where a Northing RTK subscription delivers the ±2.5 cm, fixed-in-seconds behaviour described elsewhere on this site. Read them together with the gaps in the next section: the two lists are one answer, and quoting either on its own would misrepresent it.

Contiguous United States and Canada — the lower 48 and the populated Canadian belt.
Most of Europe, including Ireland and the UK.
Japan and South Korea.
New Zealand.
Brazil.
Parts of Australia — New South Wales, Victoria, Tasmania, plus the areas around Adelaide, Brisbane, and Perth.

The gaps worth knowing about

No Alaska, no Hawaii, no US offshore territories. “US coverage” means the contiguous states.
Australia is partial in exactly the wrong places for broadacre work. Much of the Western Australia wheatbelt and the Queensland cropping country falls outside the covered zones even though the capital-city surrounds are inside them. If you farm in either, assume you are outside until a specific check says otherwise.
Boundaries are polygons, not national borders. A property near the edge of a zone deserves a specific check rather than an assumption, and so does a holding split across two blocks of land some distance apart.
Coverage is about the service, not the sky. Being inside a zone still does not help under a canopy or beside a grain bin — that is a satellite visibility problem, and no correction service can send you a satellite you cannot see.

Why coverage has edges at all

RTK corrections describe atmospheric conditions and satellite errors for a region. Those descriptions are only trustworthy where there is enough ground truth behind them to compute a good model, so a modelled correction service has real, computed boundaries rather than marketing ones.

That is also why coverage tends to expand rather than move: coverage follows infrastructure and demand, and it grows in populated, agricultural, and surveyed regions first. A location that was outside a zone eighteen months ago is worth rechecking.

It is worth being clear about what we are and are not claiming here: we do not operate a reference-station network, and this page will never pretend otherwise. What we sell is a receiver, a correction service under our own name, and a straight answer about where it reaches.

Three things that look like a coverage problem and are not

Most “coverage” complaints in precision GNSS are not coverage at all. It is worth being able to tell them apart, because the fixes are completely different.

1. Sky view. You are inside a covered zone, parked beside a shed or under a tree line, and the fix will not hold. Corrections have nothing to do with it: the receiver cannot use a satellite it cannot see, and no service can send you one. The tell is a low satellite count that recovers as soon as you move into the open. Our own drive testing was fixed 88% of a 40-minute route — the missing 12% was tree cover, a bridge, and buildings, not the correction service.

2. Phone signal. You are inside a covered zone with clear sky, and the correction age is climbing. That is the data path, not the coverage map. Corrections need about 1 kbps, which survives one bar, but not a genuine dead spot. The receiver holds centimeter accuracy for roughly a minute unaided and re-fixes within 24 seconds of the stream returning, so short gaps are a non-event; a dead valley for ten minutes is not.

3. Convergence, on the free mode. You are outside RTK coverage, running on Northing Global, and the position is wandering by a hand-span. That is not a fault — it is what a convergence-based mode does, especially while moving. It is working exactly as designed and as described honestly; it is simply not RTK.

Only the first case is about the sky, only the second is about your phone, and only being outside the zones is actually a coverage question.

How to check a specific location

A town name is usually enough. Coverage zones are large; if you are well inside one, a town resolves it.
Coordinates are better if you are anywhere near an edge, or if the nearest town is 40 km away and on the other side of a boundary.
Send the awkward location, not the convenient one. If you work across two blocks, or across a border, the one to check is the far one. The subscription is not tied to a billing address — what matters is where the receiver will be working.
Ask before buying if it matters to your decision. Support will give you a specific answer rather than a sales pitch, including “no”, which is the answer that saves everyone the most time.

We check before you pay

Your location is checked against current coverage at checkout. If Northing RTK cannot serve your fields, we tell you before you pay, not after. If you want to know now rather than at checkout, email the location and you will get a specific answer — see support.

Why we publish the gaps

Listing where a product does not work is unusual enough in this market that it is worth explaining rather than leaving it to look like modesty.

A coverage gap discovered before purchase costs a sale. The same gap discovered from the cab, halfway through a job, costs the customer a day and costs us the relationship — and in a business where the corrections renew annually, the second one is far more expensive. There is no version of this where the vague blob map wins.

It also keeps the rest of the site honest. Once a page is willing to say “not Alaska, and not most of the Western Australia wheatbelt”, the accuracy numbers next to it become easier to believe, because you can see what this site does when the truth is inconvenient.

If we get it wrong

Coverage data is maintained upstream and boundaries move. If you are told at checkout that you are covered and the service does not reach your fields, that is our problem to fix, not yours to absorb: contact support and we will sort it out rather than pointing you at a map. Tell us the location that failed, and it improves the answer the next person gets.

Outside coverage? The receiver still works

Northing Global — the free mode built into every receiver — has no coverage zones at all. Its corrections come from the navigation satellites themselves rather than over the internet, so it works on any field on the planet, with no account and no data plan.

What it gives you, measured:

Parked, after convergence: 50% of positions within 7.7 cm, 95% within 22 cm.
Driving: 24–82 cm median depending on the segment, with convergence resets under obstructions.

That is genuinely useful for marking points, checking a boundary, or finding a stake again, and it is genuinely not a substitute for RTK on repeated guidance passes. The full comparison, including why a convergence-based mode behaves so differently once the antenna is moving, is in RTK vs PPP.

Only the RTK subscription is coverage-bound. The hardware never is.

What coverage means for what you pay

Northing One is $999 with the first year of Northing RTK included, and the subscription renews at a flat $299 for 12 months. Coverage interacts with that in three ways worth knowing before you buy:

We will not sell you a subscription for a location it cannot serve. The check happens at checkout, before payment, not in a support ticket afterwards.
Being outside coverage does not make the hardware a bad purchase — it makes it a 10–20 cm instrument instead of a 2.5 cm one, permanently and for free. Whether that is worth $999 depends entirely on your work, and RTK vs PPP is written to help you decide rather than to talk you into it.
If coverage arrives later, the receiver you already own is the receiver that uses it. There is no hardware upgrade and no trade-in: subscribe, and RTK is live in seconds.

Renewal is a flat annual price with a reminder email before every renewal, no per-hour metering, and cancel-anytime — the whole of it is on the pricing section.

How to read this page in six months

Facts on this site are date-stamped so you can tell how fresh they are, and this page is the one most likely to age. The date at the top moves whenever the coverage list changes. If it says August 2026 and it is well past that, ask us rather than trusting it — a stale coverage claim is worse than no claim at all, and we would rather be told than be wrong.

Next: how Northing RTK works for what the correction stream actually does, or inside the receiver for the hardware that applies it.
