Navigating With GPS

PARTING COMMENTS

The C code provided supplies the basic building blocks for a small, low-cost yet significant navigation application program. GPS receivers are available on the ’Net for bargain basement prices. Mapping programs that provide latitude and longitude data are widely available. The C code supplied in the example program is portable, so it runs on most processors that support floating-point operations and trigonometry functions.

Now you’re on your way to creating your own navigation program. Being lost will be a thing of the past!
