Vessel Monitoring System Using GSM Communications Network

The purpose of this study is to monitor the data sent from ship server. This system relies on internet network transmit such as coordinates position, direction vessel, distance obstacles in a front speed and length trajectory server using GSM Shield SIM900 module. will use four providers Telkomsel, XL Axiata, Indosat, Tri. benefit monitoring research that it can supervision ships access via mobile phones. result respond well send coordinates, direction, obstacle speed, vessel trajectory. Then best signal strength Simpati card provider with -65 dBm
