What is the meaning of the fan shaped area behind my current position in those gps applications In osmand and other gps navigation applications, my current position is shown as a spot with a certain radius, the radius shows the accuracy of my position, sometimes there is a fan shaped area in that spot, what does that mean?
It's the direction we are facing when holding the device in front.
