GPS technology is now very much prevalent in commercial aviation. Most commercial jetliners now increasingly employ GPS navigation for initial and non-precision approach to specified airfields. The Automatic Dependent Surveillance – Broadcast (ADB-B) is the futuristic primary guidance and navigational GPS technology for which a substantial amount of research, development and investments are being poured in. The ADB-B technology also involves direct inter-aircraft communication within a pre-defined radial proximity wherein it enables the aircraft to inter-communicate their relative speeds, distances, flight paths and locations. The development of this technology is not confined to any one country but is being developed globally through strategic technological multi-lateral alliances. Besides its use in commercial aviation, the GPS ADB-B technology is also being employed in the navigation Unmanned Aerial Vehicles (UAVs). The UAV’s are primarily used for resource mapping and air surveillance imaging – a task that was previously tasked to earth orbiting satellites such as the NASA Landsat.

The all encompassing, all progressing GPS technology has further underlined its presence in the field of maritime technology. GPS digital technology has since replaced conventional electronic maritime technology and is now being employed to include such vital operational parameters as 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 regard to railroad navigation, GPS technology is widely used today to streamline such navigational essentials that include the management of rolling stock, … Read more
