Dave Wilkinson, Presenter Title: “I Know Where I Am And How I Got Here”
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) Craig L. Phillips, MS Ed. COMS
Global Positioning System 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 Craig L. Phillips, MS Ed. COMS
Global Positioning System 101 • Satellites orbit 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 Craig L. Phillips, MS Ed. COMS
Global Positioning System 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 Craig L. Phillips, MS Ed. COMS
Global Positioning System 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 Craig L. Phillips, MS Ed. COMS
Global Positioning System 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 Craig L. Phillips, MS Ed. COMS
Point of Interest = POI • Point of Interest = Landmarks /Waypoints • Use POI rich in the beginning • Preset • Downloadable maps • TeleAtlas and NAVTEQ • Manual set • Noun first, then Adjective • “North High School, East Door…” • Physical reference points Craig L. Phillips, MS Ed. COMS
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. Craig L. Phillips, MS Ed. COMS
Considerations • Everything is relative. • Take a cheat sheet on lessons…use it. • The device is a where and when tool. • GPS does not supplant O & M skills. • It’s about what works for the student not you. Craig L. Phillips, MS Ed. COMS

FYI… • “i feel like i'm "cheating" somehow, when i don't have to keep track of what street is what, where it's located, what direction i'm heading, etc... it frees my mind up to concentrate on other aspects of orientation...and then, listening to the gps as i'm riding in a car, realizing the breadth of this world that is outside my car window i have heretofore never gotten to interact with...amazing, simply amazing...” Craig L. Phillips, MS Ed. COMS
