Many Portable Digital Assistants (PDAs) now have been enabled with the Global Positioning System (GPS). This is a global navigation satellite system (GNSS) established and managed by the United States Department of Defense of the United States Air Force 50th Space Wing. GPS can be used freely by any civilians anywhere. Enabling PDAs with GPS receivers will allow it to determine its current location by transmitting precise radio signals to a constellation of 24 to 32 medium earth orbit satellites. GNSS became fully operational in 1995. Its application for navigational purposes has spread globally whether land, air or sea. It is a useful tool for tracking, surveillance, map-making, land surveying, scientific use and commerce. In the late 1990s, the first GPS enabled handsets were launched.
