Fact #1. Having a dedicated GPS device can be extremely helpful. Many people use their smartphones for day-to-day navigation. But suppose you're going out to sea, or going hiking in an area where you don't get reception. In times like these, it's a good idea to have a device that's built with your journey in mind.
Fact #2. There are many different types of GPS units. Some are meant to be used in your car. These usually have a way to mount to the windshield or dashboard. There are also small, handheld units that are designed to be taken on off-road adventures. Then there are GPS watches. These tend to be used by runners, golfers, swimmers, and other athletic types.
Fact #3. All of these devices work by communicating with a network of satellites. These satellites go around the earth two times a day, following a specific orbit. As they go, they send information to GPS receivers on the ground. This allows the receiver to know how far away the satellite is. When the receiver is in communication with at least three satellites, it can determine exactly what location it's in.
Fact #4. GPS stands for Global Positioning Systems. It was originally built to be used by the US military. In the 1960s, it consisted of just five satellites and was only used by the United States Navy. The government gave the public access to the technology in the 1980s. Today, the system is made up of 24 satellites and is used by all kinds of devices.
Fact #5. There are many features available. Avid photographers may want to look for a model that can attach to a camera and add geotags to images. That way, you can know exactly where each of your photos was taken. People who go on hikes, camping trips, or other outdoor adventures should get a unit that's ruggedly built and water-resistant.
