Real-Time Location Tracking System suitable for Global Shipping Logistics

Abstract

Recently it has become easier to figure out cargo positional information by using GPS(Global Positioning System) and wireless communication technology. The acceleration of globalization in the shipping logistics is ever more increasing the need to provide visibility, traceability and real time informations of entry, departure of vessel including cargo and status of logistic vehicle entry into each logistic base. Providing such positional information to logistics party by using wireless communication technology can bring effective operation of supply chain and reduction in logistics costs. In the previous paper, I suggested a global location tracking system based on GPS data in global shipping logistics by means of software using GPS data. However, the previous system had a problem of being inadequate to figure out a real time location movement information and was unsatisfactory on quickly searching and checking the location of global logistics hubs according to the longitude and latitude coordinates. Hence, in this paper, I suggest a real-time location tracking system that provided real-time location of the container cargos and logistics hubs can be searched quickly according to the GPS coordinates in global shipping logistics.키워드 :실시간 위치추적, 해운물류, 가시성, GPS

“…However, most locationbased services using mobile devices are based on GPS data which makes it difficult to process data on access to a specific space or area. This is where the location tracking system comes in [17]. Information on particular buildings or areas are shown as MBRs (Minimum Bounding Rectangle) and each MBR is grouped and built into an R-tree index.…”
