And

It's Background

Introduction

Maps are most reliable when used with the compass to determine orientation and direction. With the advent GPS (Global Position System) technology, you might think that maps have become obsolete. Just the opposite they have even more useful. The guide contains practical information for using the features contained in installing a GPS and Map Navigator in automobiles. This description is used to plan safe paths and navigate the vehicle towards a given goal and or incase when you car got lost you can able to find where your car is using the GPS will help you.

The system is intended for indoor as well as outdoor use; it may be coupled to other systems, such as vision, to locate landmarks that would serve as intermediates or final destinations. In the course of this paper, we will briefly identify some of the conceptual processing levels needed for mobile android/IOS software, relate the present system to this framework, discuss the multiple representations developed as well as their use in different kinds of problem-solving activities, describe the overall system architecture and show some results from actual runs.

Our goal is to install GPS and map navigator in automobile cars. And to lead you into map navigation with some basic discussions and exercises and provide you with paths to discover more information on your own, through the use of detailed references found at various sites on the World Wide Web.

STATEMENT OF THE PROBLEM

Possible Title: Installation of GPS (Global Positioning System) Technology and Map Navigator in automobiles

Specific Problem

1. How does GPS Technology and Map Navigator to be conduct?

1.1 I.T professionals who will do the system.

1.2 GPS/Map accuracy

1.3 Capability of the users on how to use the proposed system.

1.4 Compatibility of the software in other units in Androids/IOS.

2. What are the information of installing of GPS Technology in automobile cars in terms to:

2.1 GPS/Map accuracy

2.2 IT professionals

2.3 Algorithm

2.4 Programming Language to be used.

3. Any chances to conduct the GPS Technology and Map Navigator into words by means of the statements stated.

Significance of the study

The importance of this study is to improve the GPS Technology and Map Navigator. Maps are important for lots of reasons.

1. Helping us locate ourselves in the world.

2. Helping us to locate and navigate to our friends.

3. Helping us to communicate with others about our understanding of the world.

4. Helping us to locate resources.

5. Helping us to know what places are dangerous.

Scope and Limitation

The purpose of study is to install in automobile cars the GPS Technology / Map Navigator. GPS navigation and surveying techniques have limitations that may not permit desired accuracies in a given environment. The timeline of this research is on to November 2012 to March 2013.

Relevant Theories

In Einstein's Special Theory of Relativity he united space and time into one entity--space-time. Within this new continuum, time slows down as you move faster. Many have probably heard of the twin paradox, where a pair of twins is separated; one stays on Earth and the other travels on a trip to a nearby star at near the speed of light. When the traveling twin returns home he finds his Earth-bound twin much older than he is. The space trekking twin's biological clock slowed down as the speed of his spaceship approached the speed of light. This characteristic of time has been proven by comparing two atomic clocks: one stationary on the earth while the other was flown around the world aboard a jet plane. The clock that went for the ride was slower than the clock that stayed behind.

The GPS satellites are in orbit above Earth at an altitude of 26,600 km (15,960 miles) and totay in that orbit they are moving at a speed of 14,000 km/hr (8,424 mph) relative to the surface of our planet. This speed, although not anywhere near the speed of light (299,793 km/s or 186,282 mile/s) is still faster than any reference spot on the earth is moving, therefore a clock aboard a GPS satellite will run correspondingly slower - about 7200 ns/day (7200x10-9seconds/day) - than a clock on Earth. This is a very small number indeed, but very measurable and that difference needs to be accounted for.

Now for the General Theory of Relativity. In this theory, gravity comes into play and it too affects time. To be brief: a clock in a gravitation field will run slower than a clock in a weaker gravitational field. Again, looking at the GPS satellite orbiting above us, we should immediately realize that the satellite is in a lower gravitational field than we experience on the surface of the earth. Acceleration due to gravity falls off as: 1/ (radius) 2. It is not zero, as some people might believe it would be in space, but at this altitude is about 4% of the acceleration we feel here on Earth, known as "1-g", or 9.8m/sec2 (32 ft/sec2)--small, but not zero. This corresponds to an increase in the clock of about 45,900 ns/day; a much bigger affect than that provided by the satellite's speed.

The changes in time due to these properties of relativity total to an increase of
