GPS Marker and Accuracy
The GPS marker shows your position on the mobile map. The GPS button shows the quality of the fix. On desktop, you are usually reviewing saved data rather than following a live position.
The Marker And The Button
The marker sits at your position on the map. The button controls GPS and recentring, and changes appearance when a tracklog is recording or paused. See GPS Button for the illustrated guide to every button state and what tapping does.
The Marker Ring
The ring around the GPS marker has a fixed size, thickness, and colour that you set under Settings > GPS Marker. It does not grow or shrink with GPS accuracy. OMN4 shows how confident the current fix is through the GPS button colour instead, described in the next section.
How OMN4 Shows Fix Confidence
The GPS button is green when the device reports accuracy of 10 m or better and the fix is no more than 60 seconds old. It is orange when accuracy is poorer, the position is older, or accuracy or age is unavailable. It pulses while searching for a live fix.
The marker can retain a previously known position while GPS searches again. A visible marker alone does not guarantee that the position is current; check the button too.
Why The Marker Disappears
If GPS is off or the device is not supplying a usable fix, OMN4 cannot draw a reliable live marker.
Customising The GPS Marker
On mobile, open Settings and then GPS Marker to adjust the marker appearance.
The settings are:
- Outer ring size
- Outer ring thickness
- Outer ring colour
- Internal shading colour
- Direction line thickness
- Direction line colour
These settings change how the GPS marker is drawn. They do not change the device's actual GPS accuracy.
The six marker appearance settings sync through your OMN account. After another mobile device signs in and syncs, it uses the same marker appearance. If you changed a marker setting on more than one device while they were offline, the most recent edit wins.
