Large ships or vessels with a more powerful engine are often well-equipped with advanced communication devices such as satellite communications or high power two-way radio with central base stations located along the coastal line but small fishing boats are either ill-equipped or not equipped at all of any type of radio communication equipment. This paper addresses these problems by using a portable device which will give an audio visual indication to fishermen if they approach or cross international borders. An visual alert will be provided to fishermen if they about to cross international boundaries by using LCD display. Also an authority at coastal unit gives voice indication to fishermen in case of emergence purposes. Using GPS receiver, exact position can be located. The information is send to the microcontroller, which compares the current coordinates with preprogrammed boundary coordinates. If the fishermen is about to cross the border, an alarm will alert them.
Hence all these features make a complete portable device for fishermen that can help not only to move in sea but also to gain access for information even in the middle of the vast waters.

Objectives: This paper proposes the own ship manoeuvring strategy to estimate the proper target state in the bearings only tracking. Methods/Statistical Analysis: The modified gain bearings-only extended Kalman filter is used for analysis, where the gain is modifiable. In the context of Target Motion Analysis, the target state is monitored through nonlinear estimations. The own ship exact manoeuvre is to increase the range observability. Findings: The proposed target estimation algorithm is effective in maritime tracking based sonar applications. Application/Improvements: The methodology proposed here is very useful for tracking underwater targets and finds immense usage for Indian Navy.Keywords
