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)

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.

CONSIDERATIONSCONSIDERATIONS

Craig L. Phillips, MS Ed. COMS

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.

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...”22
