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-readycard. 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).
