GPS Software
The Global Positioning System (GPS) is the only completely functional satellite navigation system in the world. The United States Air Force 50th Space Wing currently manages the satellite constellation system; however, GPS is available in many different receiver forms to the general public. Recently, handheld GPS devices have started to become popular for travelers, but they usually cost several hundred dollars. A less expensive option is GPS Software for laptops. New GPS technology is now available as software that can run on a person’s laptop, and is available at a fraction of the cost of purchasing a separate device. All one needs is a GPS receiver, which differs from a traditional GPS device in that it uses the laptop’s screen and software as its display, instead of having its own display. All it does is act as an antenna to allow the software on the laptop to communicate with the satellites. GPS receivers for laptops plug into the computer’s USB port, and are usually sold for under $100. GPS software can often be downloaded for free, although companies such as Microsoft sell relatively inexpensive software packages.

Adding a GPS receiver to a laptop makes it possible for people to easily navigate to their destinations. GPS for laptops work as receivers by calculating the receiver location by measuring itself in distance to three or more GPS satellites. The satellite frequencies can calculate and measure the speed, altitude, trip time, and actual distance of the person to the final location. GPS technology in laptop computers makes it possible for hikers, campers, and other travelers to determine their location without a paper map. This technology is especially important for rescue teams to locate injured hikers. The GPS receivers enable the person to give a rescuer the exact location of where the injured person can be found.

Having access to thousands of locations on one system is extremely convenient. GPS software enables laptop owners to travel to any destination without an actual map. The maps are built into the system, and accurately depict terrain features, road networks, and even list recreation sites for stops. In short, having this technology on a notebook computer can not only be fun and informative, it can be a lifesaver.
