Meaning there is no exact number of satellit Thu, 04 Jun 2009 23:00:26 -0600 http://www.WhyGPS.com/GPSTips/6.php http://www.WhyGPS.com/GPSTips/6.php GPS is the most accurate positioning system we have today. It can locate a person in very exact latitudinal and longitudinal degrees. Plus it can even determine the exact altitude of a certain device. Innovation never stops for the GPS. Today, there are many systems that are being augmented Thu, 04 Jun 2009 23:00:26 -0600 http://www.WhyGPS.com/GPSTips/10.php http://www.WhyGPS.com/GPSTips/10.php A GPS waypoint is a marker to a particular location you want to return to in another time.
