1. Introduction
In situations like fight crash or any disaster, this leads the passengers may lose in an
unknown place or fall into seas, in that cases, it takes time duration to assemble a rescue team.
During assembly time a person may be lost forever. It’s difficult to rescue the lost person. A GPS
based life jacket helps the rescue team to save a lost person. These life vests include a global
positioning system (GPS) for tracking the lost persons. The aim of the project is to give the GPS
location to the rescue team by GPS transmitter in life vests. Rescue team receives the transmitted
signal from the GPS to the receiver.
1.1 Project Aim
The Aim of the project is to design a life vest with GPS device at low cost. The idea of
outline for this current future's life vest lies in the GPS framework and light appended on the vest
with the goal that inquiry and safeguard squads might be educated of where the casualty is. The
surface material of the life vest is a material that can deliver sunlight based vitality. The vitality
business rate adds greater than 3%, which implies that more than 3% of the daylight that lights
on the fabric can be moved into control. The rule is to embed a delicate sun powered vitality
board into the material, a board that is exceedingly bendable and flexible. As of late, visit
expansive scale catastrophe, for example, a plane crash or the Shipwrecked, debacle help is
imperative, keeping in mind the end goal to help in the brilliant window, utilizing global
positioning system situating to auspicious right position who require alleviation, not exclusively
can accelerate the help rate and more. It can make to enhance the odds of survival.
Another GPS prepared Global Positioning System tracking device, which can be appended to
a lifejacket and actuated by people in trouble adrift, has gotten endorsement to be made
accessible available to be purchased all through the United States of America. The Safe Link
R10 Survivor Recovery System is a progressive gadget planned, tried and produced by United
Kingdom based Kannad Marine. Kannad, some portion of the Orolia Group, has longstanding
ability in crisis area reference points. The waterproof, minimized and toughly built gadget is
intended to be conveyed by any individual who invests energy in the water for work or relaxation
purposes. Endorsement for the Safe Link R10 was conceded by the Federal Communications
Commission of Washington. The gadget will now be issued with a Grant of Authorization
declaration, favoring it for use in the United States. The R10 utilizes the two Global Positioning

System and Automatic Identification System innovation to send 'organized' ready messages.
These signs send subtle elements of the wearer's exact area to AIS gear on board close-by vessels
inside an ordinary four-mile range.
Signs created by the Safe Link R10 additionally show the bearing and separation of the
wearer, an inventive first for such gadgets. It is trusted that the R10 gadget will extraordinarily
enhance the odds of finding and recouping setbacks adrift. With this FCC accreditation the
United States joins a developing rundown of nations that have allowed sort endorsement for the
Safe Link R10 SRS, said Ross Wilkinson, Global Sales Director of McMurdo Ltd, another
organization in the Orolia Group. The R10 has as of late been perceived for its advancement and
innovation inside the marine security segment by being named the Overall Winner of the 2012
Pittman Innovation grants. We are charmed that buyers in the States are presently ready to profit
by this honor winning must-have security item. The Safe Link R10 is accessible through Kannad
Marine's system of universal merchants and by means of Survitec Survival Products Inc as its
select wholesaler in the United States.
1.2 Project Objective
Recreational and proficient exercises get individuals contact with water regular. Security on
and close to the water is an issue for the end of the week cruise boater and in addition for
military and save work force. Buoyancy gadgets are an essential piece of water security. Full-
body, modern survival suits and basic water ski belts are two extremes in the group of individual
buoyancy gadgets accessible. In spite of the fact that they vary enormously in the measure of
insurance, the objective of all security clothing is survival. In fact PFDs is known as Life vests
and life coats, short for individual buoyancy gadgets. They are intended to keep an individual
above water in the water in case of a crisis and are considered life-sparing hardware. The
primary capacity of a PFD is to keep a man on the water's surface in a generally upright position
to enable the individual to inhale and not need to tread water to remain above water. United
States costal Guard directions require a watercraft to convey no less than one Coast Guard
affirmed PFD per individual, including one for every individual water skiing. There are five
classifications of Coast Guard-endorsed individual buoyancy gadgets. Each of the five classes
give distinctive buoyancy and body situating details. Categories 1 and 2 PFDs are full-and half-
length vests intended to turn an oblivious individual from a face-down position to a vertical or

marginally head-back position coasting in the water. These vests are normally enormous and
massive. A category IH PFD, most usually utilized as a part of recreational exercises, is
additionally a light vest or coat. This sort is intended to keep a cognizant individual above water
in a vertical or somewhat head-back position. This sort comes in many styles and is the most
agreeable. A further contrast in the 1, 2, and 3 categories is that the particular level of lightness
required increments from category 3 to category 1. Throw able gadgets, for example, a ring float
or the light pad normally utilized by boaters as a pad for sitting are viewed as Category 4.
Category 5 PFDs are exceptional reason gadgets for air ship pilots who fly over water, rafters,
and ferryboat pilots.
1.3 Project Background
Global Positioning System (GPS) Technology is the only fully functional Global Navigation
Satellite System. There are many GPS satellites currently around the earth to transmit the signal
to specify the location, direction of the receiver. The first satellite related to the GPS is launched
in1978, the GPS became an important instrument to navigate, survey and cartography. It also
provides reference of time used in the study of earthquakes and telecommunications. This GPS is
developed originally by the United States. It’s used in military applications, but nowadays its
used in all fields. The GPS receiver position is calculated by calculating the distances between
itself and other satellites. Every Satellite has an automatic clock. When the device is ON the
receiver acquire signal and synchronize them with clock. These signals are received instantly and
analyzed to locate the position. The GPS uses Trilateration method to determine the location of
the Device. The GPS receiver basically consists of a receiver, then with help of 27 earth-orbiting
satellites, that rotates around the earth only 24 is in use others are kept for backup. If you want to
know the accurate position using the GPS, the receiver should determine using minimum three
satellites.
The receiver transmits the signal to locate itself, and it detect the three nearest satellites
positions. The receiver end determine the distance between the satellite and receiver and to that
distance it draws an imaginary sphere with X as radius from the receiver. The sphere is drawn
with satellite as a Centre. Similar process is done for other two satellites.

Figure 1 Trilateration Method
GPS can be used to assess human location. They highlighted the following potential
advantages of utilizing GPS:
1. Portable
2. Non-invasive
3. Continuous Measurement
4. Access to GPS Satellite
1.4 Scopes and Limitations
The scopes of GPS are mentioned below.
1. It is to be noted that GPS is very easy for the purpose of navigation.
2. The direction is clearly known with the help of GPS. The system of GPS is proved to be an
evolutionary example.
3. GPS comes along with numerous purposes. It is a kind of an evolutionary technology. There
are many advantages. The cost of GPS is much low when comparing to the other devices.
The GPS has many advantages. The most useful thing is that it covers the planet. As it is
having low cost, it is much easier for integrating. The navigation system of GPS provides the
best navigation system.
4. Usually, the navigation requires the map work and the map work is
5. The GPS system is being updated in regular intervals by US government. Once a while, the
user on GPS in his/her device, then it automatically tracks it accordingly. It necessarily needs

a specified and it will then be allocated with technologies. This is also very much helpful for
the users to track the location. GPS locator
6. They can even track the location like hotels nearby, restaurant and the gas stations. If the
climate changes, then GPS locates the particular direction. There are many different kind of
advantages, it makes less complex. This has the tracking system and then the navigation
system.
7. This also has few limitations. At times, GPS may sometimes get fail, so that the user need to
have a backup map and its related directions.
8. At times the GPS signal may lost due to the climatic changes.
9. The external power supply is not possible in the bad climatic regions.
10. The battery may sometimes get affected. Because of the over usage or some inner
mechanical issues,
11. Some of the gas stations provides external supply power. Sometimes, the GPS signals are not
that much accurate.
12. There are many different obstacles, some of them are trees nearby, building and at times if
there are extreme atmospheric conditions, then it is also an obstacle.
1.5 Project Plan and Methodology
We are using Formative Research Methodology for this work. The fundamental logics for the
formative investigation is as discussed by Reigeluth in the year 1989. In that, it is stated that if the user
creates a precise application of a kind of an instructional part in the design theory or the model, then there
are many weaknesses which are found mostly in the field of application which may reflect the
weaknesses in theory, and any improvements identified for the application may reflect ways to improve
the theory and at least intended for some subsection of situations for which theory was envisioned. There
are more number of notable resemblances to the logic of Developmental Research five experimental
design concepts, in which one of them creates the instances of each and every parameter for an
independent variable, the other one collects the data on those instances and the remaining one generalizes
it back to those nondependent-variable of concepts. The Replication with more diverse number of
students, the content, and those settings is now necessary in both the cases.
There are different types of formative research techniques and studies. The designed cases are the
theory which is very purposely instantiated and is usually done by those researchers for the purpose of
research. • in different kinds of naturalistic cases all around the world, there are more number of
