GPS receiver

Anything labeled GPS has a GPS receiver. Some include WAAS capability (Wide Area Augmentation System) which utilize land modules which add precision (1-2 m) to the location. Used with a mapping database, gps provides navigation capability. Basic models indicate a location, but to know the location's relevance, a user usually places in "waypoints", which are placed on a digital or raster map and downloaded to the GPS unit. Of course, the GPS receiver and the mapping software must use the same geophysical coordinate system.

Another post for me!

The strength of personal GPS really lies in the availability of maps for the local area. Being an early adopter, I paid top dollars for a GPS module for PocketPC only to find out that there weren't any local maps in my city - sold it within 2 weeks ;)
