Tip:
To optimize your settings for faster speeds and data
conservation when accessing your company network,
work in "Offline"mode and synchronize periodically to
send and receive company email. Do not use the Preview
Pane, and save or drag and drop attachments to a
desktop folder before opening them (rather than
double-clicking them in the email). For more detailed
information, see the Microsoft white paper located at:

Global Positioning System Receiver
The Express Card also has a built-in high sensitivity Global
Positioning System (GPS) receiver. A GPS receiver uses signals
from a constellation of 24 satellites with worldwide coverage
in six orbital planes to pinpoint its exact location.
Access online information when and where you need it most.
Get real-time visual driving directions, perform local business
searches, and access live traffic directly from your GPS-ready
card. Using wireless communication and GPS technology,
your card will retrieve the positions automatically with the
highest sensitivity and accuracy.
GPS satellites circle the earth twice a day in a very precise
orbit and transmit radio signal information to earth. The GPS
receiver then takes this information to calculate your precise
location. A GPS receiver must be locked on to the signal of at
least three orbiting satellites to calculate a 2D position
(latitude and longitude) and track movement. With four or
more satellites in sight, the Express Card's GPS receiver can
determine your 3D position (latitude, longitude and
elevation) as well as the horizontal 3D estimated position
error (HEPE).
