GPS using AVR is possible to develop
at home with an AVR microcontroller and a personal computer. GPS
(Global Positioning Software) is widely used across the world as a
means to aid navigation. The basis of a GPS system is a network of
satellites which are orbiting the planet, relaying information back to
the surface of the planet, and picked up by receivers which are able to
read the latitude and longitude of their global position. Not only can
a GPS system track location, but it can also detect time as well as the
velocity of travel. Such a device can be connected with an AVR
microcontroller
By hooking up a GPS system to an AVR you will be able to recreate a map
on the chip, providing full data of the GPS system. There are designs
for such tasks on the internet, and the overall process may not be as
challenging as one would imagine. In general, the code need to power
GPS using AVR is relatively short, with most of the code taking up the
bitmapping of the graphics for the map. The most commonly used method
of transmitting data is called NMEA which is based on strings of ASCII
36, and the whole meaning of the string (which always begins with a
'$') will be |
