Calculate velocity and errors from distance between GPS points
Hiking & ActivitiesHow do you find velocity with GPS coordinates? First we plot the two GPS points on a spherical model of the earth, then calculate the angle between them using a dot product, then calculate the ‘Great Circle’ distance using this angle and the earth’s radius and finally we divide by the elapsed time to approximate
