A Review On Gps And Bluetooth Based Underwater Positioning System

Abstract

This project mainly used to monitoring the positioning system based on surface nodes equipped with GPS and acoustic transducers Additionally we are adding obstacle sensors, mems sensors are adding easy to mount, since they can be placed in the hull of a ship or in the vehicle. If any critical condition occurs then alarm will on and inform the people. The Bluetooh protocol is used as the communication medium between the transmitter and receiving base station. Here in this project the receiving base station which consist of mobile phone. Inside the mobile phone android application. One of the main advantage by using Bluetooth is the communication path which is wide by using this method more detailed information could be obtained from the structural behaviour as well as the actual condition of the building structure. This will enable engineers use more precisely information for the structure analysis and repair as well as life time prediction.The main aim of this project is to underwater vehicle’s damage and also we can get structural behaviour as well as the actual condition of the  underwater position. If any critical condition that occurring the ship or in the vehicle. In this project work detailed study of installing various equipments, sensoring the information and which helps to minimise the damages for huge structures and loss human lives.

                 In this project ARM LPC2148 communicates with LCD,sensors and GPS modem.In the Sensor section it has Mems, obstacle sensor are continuously monitoring on lcd. If the value gets abnormal it will send the data to the particular  mobile phone by using Bluetooth module and buzzer will be on.
