Latitude and Longitude Display System Using GPS Microcontroller and AVRashish Sharma (B.Tech., EL Engg.)E- email: [email protected] The project is a reference to budding engineers or a helping hand to those who want to work and interface a GPS receiver with a microcontroller and create their own channel to communicate with the satellite, looking for useful information from the satellite to create an effective and efficient system. the simplest way “The Global Positioning System (GPS)” is a satellite navigation system consisting of 24 orbiting satellites. This satellite transmits a quantity of information in the form of a string (eg: latitude, longitude, altitude, time etc.) which we will discuss further. If you want a detailed description of GPS, just search the web or visit a technical tutorial website, you will get a lot of information. GPS Receiver The GPS receiver received the information in string format, transmitted by the satellites, which uses this information to calculate different parameters between it and the satellites. Using information from satellites, a GPS receiver can determine its position on the ground from the known position of the satellites. I would now like to draw your attention to the purpose of this project. In this project, we will display "Latitude & Longitude" used for positioning an object on earth. So let's talk about how a GPS receiver fixes its location on the ground, as I said above and finding the location of an object on the earth. Location Finder Let me tell you, if we want the location of an object on earth, the GPS receiver has to connect with a minimum of 3 satellites at that specific time. Now I explain this in a simple way using Figure 1.1: Fig. 1.1 In figure 1.1, I try ...... middle of paper ...... completely, then go to step (4), otherwise go back to step (1)4. Leave the first comma and wait for the second comma (since we are not looking for the tense).5. Start taking data into an array lati_value[ ] up to the next decimal point.6. Get latitude direction in lati_dir7. Do the same for longitude8. Display the values ​​on the LCD screen and return to step (1). You will get the following result on the LCD screen: Congratulations!!!! We successfully completed this project. CONCLUSION A position locator can be easily implemented with the grouping of simple commands and basic knowledge of interface devices and USART communication or it can be more restrictive if we are going to use other parameters at the same time. more knowledge is acquired and more experiences are compared. A lot of information is finally collected, I concluded with great pleasure to have achieved my objective.
