The GSM/GPRS based positional information system with integrated GPS receiver provides up-to-date location information for tracking the Tugs/ships in the port. It also allows emergency message transmission from Tugs/Ships/locomotives to Network Center. The system primarily consists of a GPS receiver integrated with a GSM Module fitted on the Tugs/ships.
The positional data acquired by the GPS receiver will be transmitted by modem as GPRS packet to network center. At the network center, the data will be collected by the GPRS server, this data will be processed and stored in a database. The user can access the data through the internet by logging in to the web interface provided. MIS Reports and GIS-GPS integration are provided for viewing the messages, statistical reports for tracking the tugs on a digitized map. Network diagram is shown in figure below.
