Abstract
Accessing the location of Gondar city for the peoples in Gondar as well as gusts; is the primary goal of our project.
Our project displays the Gondar city location name according to the data received from microcontroller based city locator using GPS and LCD system. This demonstrates how to get the location (longitude and latitude) information from GPS receiver and if that received co-ordinate corresponds to any city then it also display the name of Gondar city.
Now a day finding places in Gondar city is so difficult for peoples especially visitors. They get confusion because there is no clear city location system and also there are no street maps on most places around Gondar.

Chapter One
1. Introduction
The GPS is a collection of 24 satellites that continuously transmit coded information, which is received by GPS receiver to precisely identify location on earth by measuring distance from the satellites.[1]
GPS allows you to record or create locations from places on the earth and help you navigate to and from those places. Originally the System was designed only for military applications and it wasn’t until the 1980’s that it was made available for civilian use also. [2]
This microcontroller based city locator has so much application in the world. There are lots of places that have to be visited but have no idea where to locate them. In Gondar city locating places is one of major problem. Our project main aim is to get easy access for the location of Gondar city. For our project we uses software ,hardware and also programming language. This microcontroller based city locator system allows peoples to guide themselves to travel wherever they want to go, visit and also for different purposes.

1.1 Problem statement
Traveling to any places may be the life adventure of some peoples around the world and this comes to be a problem when it comes to our country because of different reasons some of them are listed below…
- There is no clear location guider for the places or cities in Ethiopia
- It cost additional money for guider(travel agencies)
- Peoples loses much time for searching places or cities without having someone guiding them
- Many peoples will be lost into some where places which are not safe or they will go to the restricted areas without knowing the danger they are going into …
1.2 Objective of the Project
1.2.0 General objective
Exploring GPS based city location in Gondar city
1.2.1 Specific objective
To provide access for the user or groups of user as a guideline for the location that they want to go
- Developing city Location system using GPS for positioning information.
- Providing clear location guider for Gondar city
- Minimizing additional coast for traveler
- Acquisition of city’s location information (latitude longitude) after specified time interval.
- To provide a solution to avoid wasting time for searching the exact location of the place (GPS)
1.3 Goal of the project
2009
of construction and agricultural machinery and, in the near future, reporting of exact cell-phone locations for emergency response purposes. As with many technologies, the uses of GPS extend far beyond what the original designers envisioned. As receivers have shrunk in size and weight and costs continue to drop, the number of users and applications has grown rapidly.

2.1 Methodology
2.1.0 Data gathering methodologies To prepare this project documentation we have examined different methodologies to gather relevant information that will help us to accomplish the project in well-formed manner.
- Interview:^ -^ to^ get^ the^ basic^ information^ and^ background^ information^ about^ the existing city locator GPS system of Gondar city, the team members has interviewed the some residents of the city, and the problems associated with that environment.
- Direct observation: even though interview is very important to gather information, direct observation is simple and we project team members physically observe different areas or kebeles of the Gondar city, like kebele 18, piassa ,arada .kebele 19 which have no city loctor system..

- Existing document: To get more information about the project we use earlier documents that help us to develop the project. During the analysis of documents, we give a special consideration to those documents which can bring more features to the project.
2.1.1 System development methodology
The GPS receiver collects information from satellite and generates output in form of different strings. Then, it gives these strings as an output to micro controller. After this, MAX232 level converter chip converts RS232 level signals given by GPS receiver into TTL level signals that can be given to micro controller and the AT89C51 micro controller receives all the strings from GPS receiver but extracts only one string. It extracts location information from string and displays them on LCD in proper format. Finally, the LCD panel displays location information and name of city.
The system block diagram for the process is given as follows:
Software requirement are..
- Proteus simulation software
- Microc compiler
