GPS altitude vs altimeter altitude
It is my understanding that even if a GPS is reading perfectly and your
standard altimeter is reading perfectly even on a standard day that the 2 values will not be the same. Does anyone know about how far off they are and if there is a way to calculate what the difference should be? My guess is that at different points around the earth, the correction will be significantly different, making a generic formula difficult if not impossible to write. -- Chris W KE5GIX Gift Giving Made Easy Get the gifts you want & give the gifts they want One stop wish list for any gift, from anywhere, for any occasion! http://thewishzone.com
