A Navigation Tool for Boating, Hiking and Pilotting
Price --- US$59/License
This is a necessary navigation tool for boating, piloting or hiking. NACNav lets you input the current location NAC or longitude/latitude coordinates from GPS (i.e. in WGS84 Datum)
and the destination location NAC or longitude/latitude coordinates in WGS84. It outputs the
heading angle of the destination in magnetic compass (i.e. the angle between the
magnetic north pole and the destination pointing from the current location) and the
real distance (the shortest distance from the current location to the destination along
the earth surface) as well as the magnetic declination at the current location (i.e.
the angle between the true north and the magnetic north directions). The software also
draws the results on a compass to show you the interpretation of the directions. This software
has employed the accurate algorithm for the computation of distance and heading. It uses
the World Magnetic Model - 95 to calculate the magnetic declination.
