Vaya siempre con el GPS Compass.
GPS Compass is a small but complete navigation tool, it leverages on both magnetic compass and GPS to give you always the most accurate information available.
GPS Compass shows you distance and direction to geographical location (waypoint) you can define in many ways.
GPS Compass calculates relevant points position by bearing and triangulation then saves the points as waypoints.
You can see the waypoints on a map or you can use the map to define waypoints for navigation.
The Basic version is limited in the number of waypoints you can define, it allows you up to 30 points.
GPS Compass is the basis of the shortcoming Regatta application that adds a lot of feature for sail race navigation.
