Uhm no , because if satellites are strong they rule , but if it ' s less than that both contribute so it shouldn ' t remain without location . What could happen is that data received from wifi spot isn ' t accurate enough , or it takes more time between two signals . I don ' t have many references , so I ' m basing it on my router , which gives coordinates every 20 seconds satellites instead every 1 second once they ' re stable , so I set the limit to 30 seconds . If there are ones that give coordinates with a slower rhythm than that , though , it will lose the position for a bit continuosly , so I would have to change the parameters . About the accuracy , I discard any too inaccurate data , that ' s also why it can ' t be too much wrong . The ' satellites only ' system didn ' t discard anything so it ' s a new thingAnyway I ' ll test it more myself thanks
