My GPS does not react if I'm moving too slowly: The StaticNagivation
Filter the track

Filter the track

NoniGPSPlot is directly dependent on the position provided by the GPS, but sometimes it is difficult to determine.
This happens usually when conditions are bad reception (narrow alley, inside a building, basement…) or when we disables staticnav.

The position is chaotic:

The distance calculated by NoniGPSPlot is distorted and may increase even at a standstill.

If the GPS provided false information, I can not do anything about it.
Nevertheless, it is possible to setup the parameter
'Min. Between 2 pts' in the configuration window of the track to filter a little.
Example with a min. 100ft.

Over the position is unstable, the longer it will increase this value to compensate.
But it also impact track when the signal is good.
