WHERE AM I ?



Trying to figure out where you are
and where you're going is probably
one of man's oldest problem...

There are been many solutions:



(many centuries ago...)

Historical ones:

  • Landmarks, maps
  • Dead Reckoning, compass, sextant...
  • Celestial


(now...)

Modern ones:

  • OMEGA, LORAN (Radio beacons)
  • SatNav (Satellite Doppler measuraments)
  • GPS: Global Positioning System
