GPSRTT for Vessels

We have been using the GPS technology since early 2008 to automate the capturing of vessels berth arrival (ATA) and departure (ATD) data. Initial results showed that the GPS technology combined with Auto Geofence, a software technique, can serve the purpose well if the GPS tracker works normally.

However, GPS trackers in the commercial off the shelf products bought from the market are not robust and stable enough. In order to solve the problem, ISD decided to develop and build a GPS real time tracker from the ground up for all in-house GPS tracking applications, such as reefer monitoring and vessel and truck tracking.

 

Starting from December 2010, we have been installing our own GPSRTT (GPS Real Time Tracker) on our vessels. Currently about 14 vessels are using our GPSRTT an have shown remarkable improvement in signal reception (80% on an average). ISD anticipates that the average performance can further be enhanced to achieve 98-99% improvement, or even 100% subject to the results from full deployment to be completed by the end of February 2011. 

The deployment of GPSRTT will continue to cover all our 72 own and charter-in vessels as well as the two new vessels coming into service later this year.

How GPSRTT Works

  1. GPSRTT gets its own current location
  2. GPSRTT sends the location and time information over GSM mobile network to GPS Server
  3. GPS server acts as a repository to collect all information, and detect if vessels are entering into or leaving from the area of berth by using the auto-geofencing technique
  4. Various application systems such as SchedulingSmart, may retrieve the timely ATA/ATD milestone information from GPS server



Locating Vessels on the Map
Location of the vessels can be tracked and visualized on public map services.
