DESIGN OF SHIP’S PERSONNEL POSITION MONITORING SYSTEM BASED ON LORA / GPS SHIELD USING DELPHI

Abstract

The ship escort mechanism and system in KRI / KAL in reporting the position of the ship being
guarded at this time is only limited to reports via radio communication equipment / HT. This caused
the KRI / KAL Commander's decision to be reconfirmed manually between the ship's escort Personnel
and the KRI / KAL Guard Officer. Therefore it is necessary to have a system that can monitor the
position of ship escort personnel periodically by applying LoRa (Long Range) technology integrated
with a GIS-based information system (Geographic Information System). The position monitoring
system for ship escort personnel can send coordinate data from the Client transceiver device that is
carried by the ship escort personnel periodically with the 915MHz LoRa TM protocol and receive the
closest Gateway transceiver in KRI / KAL with the same frequency with an average time of two once a
second transmits, the coordinate data received is stored in the application server database monitoring
the position of ship escort personnel in the form of markers, so that the position of personnel is
monitored periodically and can be immediately reported to the KRI / KAL Commander as decision
maker. This system can also receive coordinate data from several Client transceiver devices.
