Integrated GPS Receiver
Many ruggedized computers offer integrated GPS as an option. For those in the field, this is really handy and precludes the need to carry around an extra device (an external GPS receiver). Also, the antenna is built-in to the computer and provides the best reception. GPS is also a popular feature in computers used in cars, trucks, boats, planes, tractors, and other forms of conveyance. Numerous mapping software programs exist for road and street maps, aviation maps, marine maps, topographical maps, etc. GPS devices can also be external and connected to the portable computer via USB or Bluetooth connections.
Group Mobile Comment: Keep in mind that even though there are theoretically 12 satellites in view above the horizon at all times; mountains, buildings, trees, etc. are normally present to block the signals. Having a high-quality antenna is important if you want a constant GPS reading.
