Trekker is a powerful and efficient tool that has
been developed from the ground up with
extensive input from our customers. Trekker
users continuously tell us they would rather not
be without it because it greatly increases their
self-confidence, orientation and independence.
This resource guide will help you to empower
your students with the skills they need to get the
most out of their Trekker.
What is GPS
Trekker uses state-of-the-art GPS and digital
map technology to help blind persons find their
way in urban and rural areas. Users can pinpoint
exactly where they are, learn about area
attractions, and find out how to get to specific
destinations. Trekker provides information to
help users get to where they want to go without
having to count steps or continually ask for
directions. It therefore allows users to
concentrate more on their own mobility and not
worry about getting lost or disoriented.
The Global Positioning System (GPS) is a
worldwide navigation system formed from a
constellation of 24 satellites orbiting the earth.
The idea behind GPS is to use satellites in space
as reference points for locations here on earth.
By measuring our distance from at least three
satellites, we can obtain our position anywhere
on earth.

so we’re here to help you.
Trekker has a GPS receiver that communicates
with the satellites through wireless connection
(Bluetooth) to the PDA (handheld computer).
The PDA has a map of the user’s area installed in
its memory card and is therefore able to tell
users where they are and what is around them.
