GPS technology is now considerably prevalent in commercial aviation. Most commercial jetliners now increasingly employ GPS navigation for an initial and non-precision approach to specified airfields. the automated Dependent Surveillance-Broadcast (ADB-B) is that the futuristic primary guidance and navigational GPS technology that a considerable amount of research, development, and investments are being poured in. The ADB-B technology also involves direct inter-aircraft communication within pre-defined radial proximity wherein it enables the aircraft to inter-communicate their relative speeds, distances, flight paths, and locations. the event of this technology isn’t confined to anybody country but is being developed globally through strategic technological multi-lateral alliances. Besides its use in commercial aviation, the GPS ADB-B technology is additionally being employed within the navigation Unmanned Aerial Vehicles (UAVs). The UAVs are primarily used for resource mapping and air surveillance imaging – a task that was previously tasked to earth-orbiting satellites like the NASA Landsat
Shipping and Rail Transport
The all-encompassing, all progressing GPS technology has further underlined its presence within the field of maritime technology. GPS digital technology has since replaced conventional electronic maritime technology and is now being employed to incorporate such vital operational parameters as the ocean and inshore navigation, dredging, port, and harbor entrance approach navigation and docking, Vessel Traffic Services (VTS), Automatic Identification System (AIS), hydrographical data collection and cargo logistics.
In reference to railroad navigation, GPS technology is widely used today to streamline such navigational essentials that include the management of the wheeled vehicles, passenger information, prevention of door releases contingent to carriage platform alignment, cargo tracking signaling, train integrity, and grade crossing approach.
The applications of GPS technologies in various scientific fields are quite widespread and impactful; these include such areas as environmental and atmospheric monitoring, animal behavior studies, botanical specimen locations, meteorology, and climate research, agriculture, fisheries and fishing, acreage mapping, yield monitoring, precision planting of crops, spray and harvest monitoring, autonomous vehicle control.
Security is another very wide field that employs GOS technologies. GPS security applications include tracking of all types of vehicles – light and heavy vehicles, 20 and 40 ft. containers comprising general cargo, special air-conditioned containers for perishable food items, security monitoring of vehicles for the transfer of criminals and suspects, etc.
It is obvious that GPS technology is indeed very applicable and suited to a really wide spectrum of scientific and technological applications which involve constant monitoring and tracking data, especially if the targeted objects are important, urgent, sensitive, and precious. This includes people, animals, machinery, valuable, currency notes, etc.
