9.1 Introduction
Prior to the widespread availability of GPS, Loran, and other electronic navigation aids, pilots used visual cues from terrain to navigate. Now everyone uses GPS. We want to return to the good old days of terrain-based navigation. We will design a system that will be able to match terrain with a database. It will then use that information to determine where it is flying.
