BSEE - KB3UON
RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...

The NAVSTAR Global Positioning System (GPS), originally designed to serve global navigation for the U.S. military, has evolved into a critical element for commercial aviation, maritime, automotive, trucking, rail, and personal navigation. Once the E911 location feature is fully implemented in cell phones around the world, GPS will be as ubiquitous as wristwatches. Russia followed the success of GPS with its own GLONASS (Global Navigation Satellite System), and the European Space Agency (ESA) launched the first of its Galileo satellite in December of 2005. This very extensive listing of component and system resources will assist you in your search for information.
