GPS Tracker Jumping Around When Parked? How to Stop GPS Drift
Charles Alexis
You know the van has been parked all night. But the tracker shows it wandering around the block, or bouncing between two streets. That is GPS drift.
Why GPS drifts
GPS works out position from satellite signals. When the signal is weak or bouncing off buildings, the position can wander, even when the vehicle is not moving.
Drift is worst:
- In city centres with tall buildings, where signals bounce off walls.
- In multi storey or underground car parks.
- Under trees, bridges or metal roofs.
- When the tracker is mounted somewhere with a poor view of the sky.
Each new position is slightly different, so the map shows the vehicle “moving”.
Why it matters
Drift is not just cosmetic. It can:
- Add fake mileage, which messes up reports. See GPS tracker showing wrong mileage.
- Trigger geofence alerts when the vehicle has not moved.
- Create fake trips in trip reports.
- Make it look like a vehicle is being used out of hours.
How to fix it
1. Turn on static navigation or similar filtering
Many trackers have a setting that freezes the position when the vehicle is not moving. On Teltonika devices it is called static navigation. The tracker uses ignition or movement sensors to decide when the vehicle is parked, and ignores small GPS changes while it is.
This one setting fixes most drift.
2. Use ignition to define trips
Configure the tracker and platform to start and end trips based on ignition, not just GPS movement. If the ignition is off, the vehicle is not driving, whatever GPS says. See our guide to ignition showing on when the engine is off if ignition is not detected properly.
3. Set a minimum speed or distance
Some platforms let you ignore movement below a certain speed or distance. That filters out small jumps.
4. Improve the mounting
A tracker buried under metal, or right against the bulkhead, sees less sky. Mount it with the GPS side facing up and avoid metal directly above it.
5. Check GPS antenna connections
For trackers with an external GPS antenna, a loose or damaged antenna causes poor signal and more drift.
Accuracy problems while driving
If the vehicle jumps around while moving, not just when parked, that is a wider accuracy problem. See our guide to GPS tracker not accurate.
No more fake trips
The aim is that your platform shows what really happened. Traknova filters drift using ignition and movement data, so parked vehicles stay parked on the map and trip reports reflect real journeys.

Summary
Drift happens when GPS signal is weak. Turn on static navigation, use ignition for trips, set minimum movement filters and mount the tracker with a clear view of the sky.
