GPS-based controller module

摘要

A GPS-based integrated controller module combines in a single integrated package or module a GPS receiver, a map, and a logic or decision module which provides an output control signal or control code. The map of the integrated module provides various representations. Continuous functions are provided with various types of coordinate systems, which can use interpolation between reference points in a grid system, or Taylor series representations. The integrated module performs discrete output functions such as providing a control code or a user's location either within or out of a particular closed area or polygonal zone, where each location shares a common characteristics with the other locations in the zone.
