5 G lobal P ositioning S ystem 101 Satellites orbiting 12,000 miles above Earth 24 satellites constantly moving Two complete orbits in less than 24 hours Travelling at speeds of roughly 7,000 miles an hour July 23, 2010Craig Phillips, MS Ed. COMS5

6 G lobal P ositioning S ystem 101 First GPS satellite was launched in 1978 Built to last about 10 years Weighs approximately 2,000 pounds 17 feet across with solar panels July 23, 2010Craig Phillips, MS Ed. COMS6

7 G lobal P ositioning S ystem 101 Accuracy resolution +/- 50 feet Any weather conditions Anywhere in the world No subscription fees or setup charges to access GPS. 24 hours a day July 23, 2010Craig Phillips, MS Ed. COMS7

8 G lobal P ositioning S ystem 101 Triangulation ◦ three satellites to calculate a 2D position (latitude and longitude) and track movement ◦ four or more satellites to determine the user's 3D position (latitude, longitude and altitude) and track movement July 23, 2010Craig Phillips, MS Ed. COMS8

9 G lobal P ositioning S ystem 101 Signals travel by line of sight ◦ Can go through clouds, glass, and plastic ◦ Cannot go through most solid objects such as buildings and mountains July 23, 2010Craig Phillips, MS Ed. COMS9

10 Sources of GPS Error Signal slows as it passes through the atmosphere Signal multipath occurs when the GPS signal is reflected off objects such as tall buildings or large rock surfaces before it reaches the receiver. Number of satellites visible-buildings, terrain, electronic interference, or sometimes even dense foliage can block signal reception Receiver clock errors- receiver's built-in clock is not as accurate as the atomic clocks onboard the GPS satellites.

11 Point of Interest = POI Point of Interest = Landmarks Preset ◦ Downloadable maps  Navtek TeleAtlas Manual set ◦ Noun then Adjective ◦ “East High, North Entrance” July 23, 2010Craig Phillips, MS Ed. COMS11

12 Berthold Lowenfeld Blindness imposes the following limitations  In the range and variety of experiences  In the ability to get about  In the control of the environment and the self in relation to it. (1948) July 23, 2010Craig Phillips, MS Ed. COMS12

14 Teaching Points Everything is relative. Carry a cheat sheet…Use it. The device is a tool: where and when. GPS does not supplant O & M skills. It’s not about you…It’s not about you…It’s not about you… July 23, 2010Craig Phillips, MS Ed. COMS14
