GPS resolution is only accurate to within a couple of meters. When moving at slow speeds, the speed calculation is not going to be accurate. This is a limitation of GPS technology.

thanks, because i want to confirm that gps is enter to a geofence, with slow speed
i made a trick
i get the current point and after 8 sec i get one more point and i check the distance of this 2 points and if lower than 1 meter i triger the reset of gps
then the gps when starts gets the current point with accuracy

Sounds like a goods approach. Is it working well for you?

Yes but I still testing to find the best settings for time and distance to triger the reset

Some times when GPS start send me 2-3 meters fallse for 1sec and then return to corect position
