The Advantages of Using a Hand-Held GPS
A hand-held GPS is a small device that a person can use to find their exact location. This type of GPS differs from an embedded GPS in several ways.
There is absolutely nothing wrong with embedded GPS devices, and they are actually much more popular when compared to their hand-held counterparts. However, a hand-held GPS will work much better than an embedded version in a variety of scenarios.
This is a feature that not many embedded GPS devices have. A hand-held GPS enables a user to set tracking points on the device. This is very beneficial for people who go camping and hiking frequently. While hiking with a hand-held GPS unit, tracking points can be set for safety.
There is no way to get lost when hiking if tracking points are being set while on the trial. The ability to set tracking points is also great for people who like to track their location while camping. The tracking feature lets users know where they have been, and it tells them where they’re going.
Advanced Topographical Information
The extra information that a hand-held GPS provides is very useful for certain situations. Unlike a traditional GPS unit that only shows a standard map, hand-held devices show topographical information that is especially useful for people who go hiking often.
A hand-held GPS unit also shows a compass that is very useful for people who engage in activities like geocaching, which is a form of treasure hunting that requires a hand-held GPS.
How a GPS Works
A large number of individuals have no clue how a hand-held GPS works. The process is actually quite simple. A GPS device uses about 30 to 40 satellites that are in space. A GPS unit is sent microwave signals from the satellites that are orbiting the planet.
The microwave signals contain information, like the current position of a satellite and transmission time. The GPS unit uses the raw information in the microwave signals to determine where the person who us holding the unit is standing. It uses trilateration to determine an exact position.
For an accurate position, a GPS device needs to receive information from at least four different satellites. There are a few other great benefits to gain from using a hand-held GPS. People who like to catch fish while on a boat use a hand-held GPS that might also be equipped with a fish finder.
