What is Waypoint Navigation? Navigation along a series of straight-line segments called legs Beginning and endpoints of each segment are defined by latitude and longitude The endpoints of each segment Multiple legs or course segments may be pre-plotted to avoid obstacles reducing risk Usually begin and end at aids to navigation Plotting and measuring waypoints are necessary steps in using GPS to navigate
