Chapter 5 Using GPS Navigation
Introduction
The MC75A includes Global Positioning System (GPS) technology using the SiRF III chipset. GPS technology is
based on a worldwide system of GPS satellites orbiting the earth that continuously transmit digital radio signals.
These radio signals contain data on the satellites’ locations and their exact clock time and are used to determine
your location on the earth.
Software Installation
Third-party GPS navigation software is required. Evaluation software is available from various suppliers. For
example; VisualGPS, visit: http://www.visualgps.net/VisualGPSce/
If interested in purchasing GPS navigation software check with the GPS software vendor (before purchasing,
downloading, or installing any software) to determine that the application is compatible with the MC75A. Refer to
the application’s user guide for application installation and setup information.
