What Is GPS ASSISTED AUTONOMOUS VEHICLE(REMOTE CONTROL HELICOPTER)?
Its a project that use RC helicopter that can fly autonomous within control it using a coding from PC/laptop.


INTRODUCTION
At nowadays, as we known the accident is always happen involved motorcycle,cars and also bus. If accident happen crash to ravine or lost in the forest, we had a lot of trouble to trace the position of the victims and needs lot of rescue team to locate them.

Furthermore, the system of delivery nowaday needs worker to sent the item on time. Others, at the farm and garden we need used mechine in manual to spray poison and fertilizer for plant. This need a lot of energy of human and also it will harmfull to us. Other than that, at the factory or else, we need human to surveillance the area for the safety purpose.

This project called global positioning system(GPS) autonomous vehicle will improve all the problem statement above. This project will give benefit such as if accident happened involved lost vehicle ,we are easy to locate them using this system. Other than that, it can be use for safety purpose for tracking the vehicle if theft or missing.

Second benefit from this project is using RC helicopter, we can used it in agricultured industry such as, fertilizer and poison will be sprayed with fast and easy using Rc helicopter. Others, we also can used this project for safety purpose in industries or office. Suppose that this RC helicopter will be equip with surveiliance camera and just control the RC helicopter to survey the areas.

Lastly,if this project is fully successful. It can be used for comersial purpose and can be sold in the market.
PROBLEM STATEMENT
The main tasks for this project, and at the same time to complete this project, there are several major problems to be faced. For example, there is a major problem on the remote control, because we need to chose whether it should be using wireless, or infrared. We also need to know the frequency to be used to control the RC helicopter. Using wireless is better for a long distance rather than using infrared, RC helicopter can go the distance is very close and not far away. The second problem faced is the ability of the batery RC helicopter, RC helicopter, if small, it only lasted for 7 minutes.  But if bigger, it should be to heavy the helicopter to fly. In addition, in connection with the GPS as we know, GPS is limited to areas with no obstruction from above, if there are barriers that interfere with, most likely signal will disappear and we will not be able to detect that the GPS. 
              A further problem is there about the coding that will be used to automatically control the RC helicopter, and what materials will be used to control the RC helicopter through a laptop or computer. Not only that, we still do not know how much distance it can fly , as we know, small-sized RC helicopter can only fly as far as 6 to 7 meters high, and we need a tool that can control the RC helicopter to go far away. At the same time we also need to know the size and ability that can be reached by one mini helicopter.How many weight that the helicopter can fly up because they may be modified to allow some new things put on it such as batery, gps module,wireless tranceiver and anttena. 
               The last problem is whether the equipment should be used to complete the project, as dimension above, the tool should be used for it to go further, coding used, other items like IC that should be used and others. 

LITERATURE REVIEW

Nowadays as we know they are many types of car that have been install with security at their cars. That is install the GPS tracking at car for prevent the car from be stolen. But not all of car in Malaysia install that GPS at their car. Most of the car that have been install GPS tracking,we can detect that where is the car if the car is stolen. As we know , The GPS-based car security systems works based on the concept of utilizing satellites to provide our car with its current coordinates, and you would be able to have the knowledge of your exact location on a global map with the assistance of the in-car GPS map.We can also receive information such as  travelling speed as well as directions, thus it could prove to be a useful tool to have. And when we installed a GPS-based security system in ours car, in case the car gets stolen, we would be able to detect the exact coordinates of your car, no matter which part of the world it is located at.Then we know that this security is very important to us in nowadays.
Vehicle tracking using GPS (Global Positioning System) is fully integrated into the VTS (Vehicle Tracking System). GPS was developed by the U.S. military to enable accurate navigation. 24 satellites have been placed in orbit some 20.000 km from the earth's centre.The vehicle to be tracked is fitted with a GPS receiver and a small antenna. GPS satellites are continuously transmitting a radio message containing information including when the data was sent, which satellite sent it and the current reliability of the system. The GPS receiver fitted in the vehicle receives information from at least 4 satellites and carries out the necessary calculations to determine its current position.


METHODOLOGY

The main focus on this project is using transmitter to transmit data from device to another device with simultaneous and stable. This need be done by doing research and development using all material and equipment and test their reliability to confirm with is the best for this project. For the transmitter, it have lot of type such as infrared, radio wireless. Infrared is a very cheap component device on the market but have lot of difficulties when using them. This shown infrared cannot transmit far away and need straight forward signal. Compared to wireless device, it is more equivalence and more reliable to do this work, because it is also not very expansive and easy get from local market. Also wireless can transmit over 1km if using high gain antenna and high gain transmitter.
Secondary focus in this project is using and modified the global positioning system(GPS) to communicate data through computer and manage them to control the RC helicopter automatically and perfect with their positions. After that, make the coding code to easy configure and user friendly to control the RC helicopter to any coordinates wanted. But for RC helicopter also need something special to maintain the high from surface.

OBJECTIVE

          This research study intends finish improve and develop remote control (RC) Helicopter from manual operation to autonomous operation using Global Positioning System and Transceiver system.
·         Use GPS tracking on RC helicopter
·         Controlling RC helicopter using coding from laptop.


BENEFITS AND CONTRIBUTION



According to studies made, there are some advantages available when the project is completed. For example, we can determine the position of a vehicle or in the projects of RC helicopter with a remote control, so we do not have to follow the vehicle or the RC helicopter to find out the real position of the vehicle and the RC helicopter. In addition, if we can add applications to the RC helicopter camera, we can use it to monitor a remote place without having to go to the place, enough to be some where and send the RC helicopter to a place desired.

            In addition, if the project is successful, it can be used commercially. It can be sold in the market for public use. It can be used at any place for the purpose of monitoring a location, or been used to examine damage to a place where high place by the movement of people.

CONCLUSION
As a conclusion, these project actually to improve and develop remote control (RC) helicopter from manual operation to autonomous operation using Global Positioning System (GPS) and transceiver system.  This project base on fully controlled by two way communication using high gain transmitter and receiver. In this project also, we need to know about how to design and create a small circuit but high productivity. Because for the RC mini helicopter is hard to fly with heavy equipments attach to them.
The project also will produce new development for two ways long range data transmissions between two devices connect with frequency with stable connection. In addition to create this project, we need to research any equivalent device and made suitable choice to archive our target. Also these projects, we need do a lot of study in microcontroller to archive autonomous controlling on RC device.
