The
Global Positioning System (GPS) is the most significant recent advance
in navigation and positioning technology. In the past, the stars were
used for navigation. Today's world requires greater accuracy.
The new constellation of artificial stars provided by the Global Positioning
System serves this important need.
GPS is an aerospace technology that uses satellites and ground equipment to determine position anywhere on Earth. Anyone with a small receiver can use the system at no cost. GPS has drastically changed methods of navigation and is fast becoming important in everyday life. |
