GPS has a variety of applications on land, at sea and in the air. The most common airborne applications are for navigation by general aviation and commercial aircraft. At sea, GPS is also typically used for navigation by recreational boaters, commercial fishermen, and professional mariners. Land-based applications are more diverse. GPS is now commonplace in automobiles as well. Some basic systems are in place and provide emergency roadside assistance at the push of a button (by transmitting your current position to a dispatch center). More sophisticated systems that show your position on a street map are also available.
User interface refers to the method of communicating with the device. These can include; various types of keypads, touch screen or thumb stick.
Most of the new sophisticated systems show your position on a map. The Basemap GPS unit will show interstates, highways, lakes, rivers, railroads, cities, airport location etc. The Mapping GPS units have the ability to download detailed maps from PC.

A grid is a map coordinating system that uses square zones to relate positioning measurements for establishing points of reference. Some systems will have (multiple) preinstalled grids of countries built into the GPS OS. MGRS - Military grid reference system. OSGB - British national grid reference system. USNG - United States National Grid. UTM - Universal Transverse Mercator coordinate system. WGS - World Geodetic System.

Many GPS systems have preset trip calculations capable of showing your average speed, total distance traveled, time spent moving, time spent stopped, and other information such as; Shortest Time (fastest time) allows you to calculate your route using shortest distance, considering speed limit factors Shortest Distance / route determines your best route by shortest distance traveled Least Use of Freeways calculates your route through city and side streets enabling you to stay off the highways when possible Most Use of Freeways provides directions over freeways, highways and interstates.

GPS System
Waypoints are locations or landmarks worth recording and storing in your GPS. These are locations you may later want to return to. They may be checkpoints on a route or significant ground features. (E.g., camp, the truck, a fork in a trail, or a favorite fishing spot). Waypoints may be defined and stored in the unit manually, by taking coordinates for the waypoint from a map or other reference. This can be done before ever leaving home. Or more usually, waypoints may be entered directly by taking a reading with the unit at the location itself, giving it a name, and then saving the point. Waypoints may also be put into the unit by referencing another waypoint already stored, giving the reference waypoint, and entering the distance and compass bearing to the new waypoint.
