Navigational Tools Now Enabled With GPS
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.
Why Must You Own A PDA Gadget?
A personal digital assistant (PDA), also called a palmtop computer, is a handheld computer. Color screens as well as audio capabilities have been introduced into the newer PDAs so that they can also be used as smartphones or mobile phones, portable media players or web browsers. Many PDAs can now access the Internet, intranets or extranets using Wi-Fi, or Wireless Wide-Area Networks. Touch screen technologies too have been introduced.
