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.
GPS has been incorporated by many mobile phone manufacturers. PDAs enabled with GPS are in use widely in sports to calculate time, speed and distance. It is extensively used in navigation. Tracking of movement, customized directions and maps, detailing of journey and planning of trips can be carried out precisely and quickly. Palmtop Software’s Route Planner application can be used to detail route maps as well as travel plan. Indicating the starting and destination point or pointing and clicking the route you wish to take are all that is required to do. Realtime navigation too employs GPS enabled PDAs. New cars were fitted with this device. The traffic conditions, road conditions, dynamic routing and roadside mobile radar guns were displayed to assist the driver.
The PDA market has been remarkably upbeat with newer models incorporating newer technologies as the GPS and touchscreen. Some of the popular PDA models are the PalmOne M515, Palm TX, Palm Z22, Pharos 535e Traveler , HP iPAQ 111 Classic Handheld, Palm TX Handheld, Palm Tungsten E2 Handheld, Nokia N810 Portable Internet Tablet.
PDAs have many applications in various sphere of human activity. In the area of health care, it could be deployed to assist in recording symptoms, diagnosis of diseases, determining the line of treatment and assisting in the selection of drugs. In the field of education, PDAs can be particular use such as digital note taking, dictionaries, word processing, spell-check, storage of e-books and their use, and digital planning besides others.
