GPS units are being used now both as dedicated handhelds and in Android and other smartphones.
Handheld GPS devices are traditionally used by hikers, hunters, and other outdoor people. There are specific models of handheld GPS units, often known as Outdoor GPS, that are used in these outdoor activities.
Increasingly, the GPS in an Android phone is being used for navigation. The Android GPS can get its location from the GPS Satellites without depending on cell towers. It can also store maps for outdoor activities on a storage card. By using an Android GPS app, users are able to choose what style of navigation is appropriate for their activities.
GPS devices use the Global Navigation Satellite System. This system is operated by the United States Department of Defense. The satellite locations are to triangulate a user's positions Handheld GPS devices, sometimes known as "receivers," give users accurate coordinates of their current location to help them navigate to trails and custom waypoints.
Here are some of the tradeoffs between the Android GPS and more traditional handheld units.
