INTODUCTION

This project is a reference to budding engineers or a helping hand to those who willing to work and interface a GPS Receiver with microcontroller and making their own channel to communicate with satellite, seeking for some useful information from satellite to make a effective and efficient system.

GPS

In a simplest way ‘The Global Positioning System (GPS)’ is a satellite-based navigation system that consists of 24 orbiting satellites. This satellite transmits an amount of information in string format (e.g.: latitude, longitude, altitude, time etc.) which we are going to cover further. If any want a detailed description about GPS, just search on web or visit a technical tutorial website, you will get plenty of information.

GPS Receiver

GPS Receiver received the information in string format, transmitted by Satellites, which uses this information to calculate different parameters between it and satellites. With information from satellites, a GPS receiver can fix its location on the ground from the known position of the satellites.

Now I want to drag your attention on the purpose of this project. In this project, we are going to display ‘Latitude & Longitude’ used for positioning of an object on the earth. So let’s talk about how a GPS receiver fixes its location on the ground, as i above said and the find the location of an object on the earth.

Position Locator

Let me tell you, if we want an object location on the earth, GPS receiver have to connect with minimum 3 Satellite at the point of time. Now i explain this in a simple way by the help of fig 1.1:

4. Leave first comma and wait till second comma (since we not looking for time).

5. Start taking data in an array lati_value[ ] till the next comma.

6. Get latitude direction in lati_dir

7. Do the same for longitude

8. Display the values on LCD and go back to step (1).

You will get following result on LCD:

Congratulation!!!! We have successfully done this project.

CONCLUSION

A position locator can be easily implemented with the grouping of simple controls and basic knowledge of interfacing devices and USART communication or it can be more compelled if we are going to use some other parameters with the same time.

Well more knowledge is gained and more experiences are faced. Lot of information’s are collected ultimately, I have concluded with a great pleasure for achieving my aim.
