ABSTRACT
 In day-today life we hear about many Tamil fishermen being
caught and put under Sri Lankan custody and even killed.
 The sea border between the countries is not easily identifiable,
which is the main reason for this cross border cruelty. Here we
have designed a system using embedded system which protects
the fishermen by notifying the country border to them by using
Global Positioning System (GPS) and Global system for mobile
communication (GSM).

INDRODUCTION
 Global Positioning System (GPS) provides a wide range of navigation
and timing services with the combined interlocked usage of the GSM
technology, it can be used for border security tracking of boats and
ships in the oceans.
 Today Global Positioning System (GPS) technology is becoming the safe
tool for navigation purpose. The position and location information can
be viewed in electronic map via GPS receiver.
 In this paper, a survey is done on various methods of tracking and
alerting the fishermen in maritime using GPS.
 The tracking system uses the electronic system installed on a vessel,
and with software design which allows the user or owner to track the
vessel location based on latitude and longitude data.

EXISTING SYSTEM
 Lack of communication between shipping boat.
 Inability to identify the border.
 Fishermen suffering in emergency cases.
 Could not carry heavy antenna in small ﬁshing boat.

PROPOSED SYSTEM
 The proposed system is used to detect the
border of the country through the specified
longitude and latitude of the position, not
only between Sri Lanka and India but all over
the world.
 The proposed system uses a GPS receiver
which receives signals from the satellite and
gives the current position of the boat.
 The GPS receiver receives the signal and
converts it into desired data message.
 If the vessel is found beyond the border, then
an alarm is generated along with a message
transmission by GSM.

WORKING PRINCIPLE
 The GPS Modem will continuously give the signal which
determines the latitude and longitude and indicates the position of
the fishermen to them which gets read and displayed in the LCD.
 The same data is sent to the mobile of the fisherman and
simultaneously the same data is sent to the Sea border security. An
EEPROM is used to store the data, received by GPS receiver. The
hardware which interfaces with microcontroller are LCD display,
GSM modem and GPS Receiver.

.
 Then the controller unit finds the current location
by comparing the present latitude and
longitudinal values with the predefined value.
 Then from the result of the comparison, this
system aware the fishermen that they are about
to reach the nautical border. The area is divided
into four zones- normal zone, warning zone, zone
near to restricted zone and finally the restricted
zone.

.
 If the boat is in normal area, then the LCD
displays normal zone. Thus they can make it
clear that the boat is in normal area.
 In case it moves further and reaches the warning
zone, the LCD displays warning zone. If the
ﬁsherman ignores the warning or fail to see the
display and move further, and if the boat enters
the zone nearer to the restricted zone the alarm
will turn on and the speed of the boat engine
automatically gets controlled by 50%.

CONTROLLER
 Microcontroller 89s52 acts as a
main control block of the proposed
system.
 This data is read by the
microcontroller which fetches the
location information. These
information is in the standard
NMEA protocol data format . GPS
modem transmits the data in
RS232 protocol, where as
microcontroller supports TTL,
hence MAX 232 acts as protocol
converter

COMPUTATION OF CONTROLLER
 The current position received from
GPS is stored as S1 (latitude), S2
(longitude). The latitude S1 is
compared with stored latitudes.
 If latitude match, then adjacent
latitude and longitudes (X1, Y1 and
X2, Y2) are retrieved from stored table
and substituted in the equation given
below:
 By simplification, we get ax + by=c
Position Latitude Longitude
Position 1 12° 05'.0 N 82° 03'.0 E
Position 1 12° 05'.8 N 82° 05'.0 E
Position 3 12° 08'.4 N 82° 09'.5 E
Position 4 12° 33' 0 N 82° 46'.0 E

GLOBAL POSITIONING DEVICE
 These GSM modem can accept any
GSM network operator SIM biked
and act just like a mobile phone
with its own unique phone number.
 The modem can either be
connected to pc serial port directly
or to any microcontroller.

APPLICATIONS
 SMS based Remote Control & Alerts
 Security Applications
 Sensor Monitoring
FEATURES
 Highly Reliable for 24x7 operation.
 Simple to Use & Low Cost.

MICROCONTROLLER-AT89S52
 8051 is the name of a big family of
microcontrollers. The device which
is used in our project was the
‘AT89S52’ which is a typical 8051
micro controller manufactured by
Atmel.
 The 89s52 has different ports each
one having 8 Input/output lines
providing a total of 32 I/O lines
.

FEATURES OF MICROCONTROLLER
 Compatible with MCS@-51 products
 8k Bytes of in-System programmable (ISP) Flash memory-Endurance:10,000
Write/ Erace cycles
 4.0v to 5.5v operating Range
 Fully static operation : 0 Hz to 33 MHZ
 Eight Interrupt Sources
 Dual Data pointer
 Fast Programming Time

BENEFITS
 The hijack of the ship by the pirates can be eradicated.
 The lost ship wrecks due to natural calamities can be identified
 By keeping the kits in the entire boats and by knowing the locations
of all the boats we can use our kit to assist the traffic.
 Incase of any accident on the sea, it can be detected by the system
and the accident location of the boat is sent to the rescue team.

CALCULATING THE POSITIONS
.
. .
 Because GPS receivers do not have
atomic clocks, there is a great deal
of uncertainty when measuring the
size of the Spheres.
 All possible distances to the satellite
are located on the circumference of
the circle.
 If the position above the satellites is
excluded, the location of the receiver
is at the exact point Where the three
circles intersect beneath the
satellites.
 Because the relative size of the
spheres is known, there is only one
possible point where they can
intersect.

ADVANTAGES
 Accuracy determination of location
 Maintenance cost is low
 Easily replaceable

CONCLUSION
 Thus the fishermen can easily identify the national sea borders
and therefore prevents them from entering their area.
 The system provides high accuracy and high precision values
of the Latitude and Longitude.
 This model proves to challenge the already existing model
which just uses a GPS device to track the border and make the
boat move backwards .Hence; along with saving lives it also
establishes good relationship with the neighboring countries.
Piracy of ship can be controlled.
