GPS Tracker Accuracy: What 5–10 Metres Actually Means in Practice
October 13, 2026
Quick answer: 5–10 metres is a radius, not a dot. In practice it means the map shows the right street, the right driveway and usually the right end of a road — but not which parking bay. That is accurate enough to find a vehicle and not accurate enough to navigate to it by screen, and it is what the vast majority of outdoor GPS trackers deliver.
Accuracy figures are the hardest specification to judge, because a number in metres means nothing until it is put on a surface you know. This page does that, and it also covers the two questions that follow: why the marker moves, and when an offset is a fault rather than normal behaviour.
Putting the number on the ground
| Accuracy | What it means where you park |
|---|---|
| Under 5 metres | You can tell which section of a short driveway the vehicle is on. This is the good end of what consumer trackers achieve outdoors, and it is not guaranteed everywhere. |
| 5–10 metres | The right property, the right parking row, the right end of a street. You may need to look at two or three vehicles in a row of parked cars. This is the published figure for the VITALGLOW trackers outdoors. |
| 10–25 metres | The right block rather than the right address. Enough to know the vehicle went where you thought, not enough to walk straight to it. |
| Worse than 25 metres | Something is reducing the view of the sky — a garage, a multi-storey, a dense city centre, or heavy metal above the device. |
Why it changes from place to place
Accuracy is decided for the most part by how much sky the unit can see, and by what is standing next to it. That is why the same tracker is precise on an open road and vague three streets later.
- Open sky. Best case. A clear view in every direction is where the quoted figure comes from.
- Urban streets. Tall buildings on both sides reflect signals, which pushes the marker sideways. This is the classic "wrong side of the road" effect.
- Garages and underground parking. No clear sky view. Expect no useful position until the vehicle comes out.
- Metal above the device. A tracker under a steel cover, inside a container or beneath heavy equipment is working against the material it is mounted on.
- The first minutes of a journey. A unit that has been still is re-establishing its position. Early points are usually the least precise of the trip.
The offset that worries people most is usually the most normal one. A marker that sits on the far pavement while the vehicle is clearly on your side is what a 5–10 metre radius looks like in a street with buildings on both sides. If it settles within a minute or two of the vehicle moving, nothing is wrong.
Telling a normal offset from a fault
An accuracy problem is a fault when it behaves like one, and the distinction is straightforward once you know what to look for.
| What you see | Most likely explanation |
|---|---|
| The marker is out by a few metres, then corrects once the vehicle moves | Normal. Sky view was briefly poor. |
| The marker is consistently offset in the same direction, all day | Worth checking the mount: metal directly above or around the device degrades what it can see. |
| The marker jumps between two distant places | The unit is in an area with poor sky view and is estimating. Move it somewhere with a clearer view and re-check. |
| No position at all, for a full day, outdoors | Not an accuracy matter. Work through the app and device checks instead. |
What accuracy is not for
It is worth saying plainly, because expectations cause most of the disappointment here. A consumer GPS tracker is a finder, not a survey instrument. It will not tell you which bay in a car park, it will not guide you to a specific door, and it will not remain precise inside a building. What it will do is tell you that the vehicle is at this address, it left at this time, and it went by this route — which is the entire job for which people buy one.
Every outdoor accuracy figure on this page is the one published on the product listings: typically 5–10 metres in open conditions.
If your tracker is reporting positions that are consistently further out than that, email cs@vitalglowlink.com with your order number and what you have observed — that is a case worth investigating, and tracker units carry a one-year warranty with a replacement rather than a repair.
If you are choosing a tracker, the magnetic 4G tracker with the SIM and data included is the model these figures come from.
Why this page exists
Stores publish accuracy as a number and leave the interpretation to the buyer, which is how people end up expecting a dot on a map and getting a radius. The number is not vague once it is put on a driveway: at 5–10 metres you will find your vehicle, you will not need to search the neighbourhood, and you should not expect to be told which bay.
Questions about this
Is 5–10 metres good enough to find my car?
For finding a car it is more than enough. A 10 metre radius is smaller than most parking rows, so it tells you which part of a car park you are standing in rather than which bay. That is the job a tracker does: it gets you to the vehicle, and then you look.
Why does the dot sometimes look like it is on the wrong side of the road?
Because accuracy is a radius rather than a point. A 5 to 10 metre radius on a street with buildings on both sides can easily place the marker on the opposite side, especially at the start of a journey before the unit has settled. It usually corrects within a minute or two of movement.
Does driving into a garage break it?
No, it stops reporting position accurately until the vehicle comes back out. Indoors there is no clear view of the sky, and a tracker cannot do better than the signals it receives. The unit itself is unaffected, and the record resumes when it returns to open air.
Why do manufacturers state different accuracy figures?
Because they are quoting different conditions. A figure measured on an open road and a figure measured in a city are not comparable, and some listings quote the best case. Treat any figure in the single-digit metres as the same thing: an accurate outdoor radius, not a precise point.
Interpretation is one question and which brands state an accuracy figure at all is a different one, and both matter before comparing two products.
