Microcontroller Based GPS Data Logging Techniques

The GPS system is a precise navigation and
positioning system. Developed in 1973 by the
Department of Defence (USA), the GPS was originally
designed as a military tool to assist soldiers,
military vehicles, planes, and ships to accurately
determine their locations on Earth. Today, GPS is
used widely in military, commercial, industrial, and
leisure applications. One of the widest commercial
uses of GPS is on street-level route guidance that
helps a driver to navigate to an address or to a
post-code. This book describes the basic principles
of the GPS system and then the design of a
microcontroller based GPS data logger device is
given in detail, including the full source code.
With the help of the device, the coordinates of a
person, animal, or a vehicle can be stored on an SD
card and then the Google Earth mapping program can
be used to display the user track on a street-level
map.
