What waypoint means?

The waypoint is a point defined by a geographical position, latitude and longitude coordinates and in most cases altitude, used by the GPS navigation tools. Waypoints are represented on screen as points with name or representative icon.

Why do planes use waypoints?

In aviation Waypoints may be a simple named point in space or may be associated with existing navigational aids, intersections, or fixes.

Why do we use waypoints to find our way?

A waypoint is a reference point that helps us know where we are and where we’re going. Whether we are walking, driving, sailing, or flying, waypoints help us find our way.

How are GPS waypoints different from other navigation systems?

GPS waypoints are much more specific: They identify an exact spot on Earth. Waypoints in the atmosphere or outer space usually include altitude. These waypoints let pilots know how tall a mountain is, for example. GPS and other navigation systems will often combine waypoints.
