Rallycheck GPS accuracy
When using the Rallycheck app, we constantly measure the accuracy of the GPS signals. The app shows the accuracy on the bottom if the screen next to an icon. In this example you can see thet the accuracy is 8 meters. Normaly this is about 3 to 4 meters.
Interested in the quality of your smartphone GPS signal?
We tested a number of smartphones with GPS to make sure they work correctly with Rallycheck. Any phone with GPS should work, but the more GPS signals, the more precise Rallycheck can check your route. The key factor in the European area is the support of the Galileo GPS system. If your phone supports Gallileo, then you’ve got the best quality.
