Vlsi Based Accident Information and Car Security System

The Global Positioning System (GPS) is a constellation of twenty four satellites that can pinpoint any position on earth using a GPS receiver. Used to calculate exact position, speed and time, there are tremendous

The development of Global Positioning System (GPS) devices was offered an optimal scenario when the

Consisted of 24 satellites, the system could pinpoint a GPS receiver anywhere on the globe with an accuracy of several feet to several yards

Today the accuracy of GPS navigation is not questioned, however, there are still some Applications that use GPS to plot routes between two points and can be very inaccurate because it is hard to determine the difference between locations [5]. For example if you are on a trail that is not registered a GPS could give you an incorrect route. Also a GPS receiver will give inaccurate readings in a forest or a city with tall buildings because satellites have to send clear signals to GPS

The 24 satellites that make up the GPS space segment are orbiting the earth about 12,000 miles above us. They are constantly moving, making two complete orbits in less than 24 hours. These satellites are travelling at speeds roughly 7,000 miles per hour.

Essentially, the GPS receiver compares the time a signal was transmitted by a satellite with the time it was received. The time difference tells the GPS receiver how far away the satellite is. Now, with distance measurements from a few more satellites, the receiver can determine the user's position and display it on the unit's electronic map.

GPS sensors are receivers with antennas that use a satellite-based navigation system with a network of 24 satellites in orbit around the earth to provide position, speed , and time information.

Global Positioning Systems (GPS’) are widely used around the world. It’s a system composed of satellites, computers, and receivers. Their purpose is to send precise back specific details of their position (in space), back to Earth. With this device we can calculate precise positions and also the speed and time of automobiles location. GPS’ receive their signals from the satellites in space. They are used for navigation devices, in cars, phones and GPS’ themselves!

In order to measure the distance of the satellites, GPS receivers measure the time it takes for radio signals sent from the satellite to reach the base station on Earth. Once we have the precise time it takes we can plug that number into a simple equation and we have our answer.

GPS or Global Positional System is the use of satellites to determine the position of devices that can receive the

The vehicle tracking system works in a way that a hardware device (product) called Cotrac is installed and placed into a vehicle which then sends and transmits the vehicle’s location to the server and can be assessed through mobile application and via the internet by customers.

The use of cell phone has rapidly become an integral part of our lives and has become the source of economic growth and employment opportunities at the country level (Madden and Savage, 2000 & Sridhar and Varadharajan, 2007). In many countries, mobile phones are often people’s only way of telecommunication (CSR Report, 2003). They are addressing their specific needs and encouraging the use

The vehicle tracking system is very useful in tracking and management for fleet. It is the technology used to determine the location of a vehicle using different methods like GPS and other navigation systems operating which uses satellites and ground based stations. Modern vehicle tracking systems use GPS technology to locate and keep monitoring our vehicle anywhere on earth, but sometimes using different types of automatic vehicle location technology are still another option. The vehicle tracking system is fixed inside the car and gives location of the car in real time and the data can even be downloaded in a computer which can be used for making analysis in future as it can be viewed on electronic maps through internet and software. The device contains modern hardware and software components that help in tracking and locating vehicles in both online and offline mode. A tracking system comprises of mainly three parts- unit in vehicle, fixed based station and

From the past few years it is said that “every mobile company are making the smartphone and feature phone. And increasing the computing power of mobile phone, rapidly increase the smart phone mobile application. Most of the people from developed countries cannot imagine leaving their home without mobile phones. Not only the developed countries but also the developing countries the mobile application usage rate is growing rapidly. The mobile application are available in different areas like social networking, games ,news and magazines, travel, weather, health & fitness, books and many more.”

The worldwide market for global positioning system (GPS) navigation and locationbased services has been growing exponentially and is expected to rise to 13.4 billion Rupees in 2014, with a high compound annual growth rate. Although still at a nascent stage in India, the GPS navigation market holds tremendous potential for growth, driven by its increasing acceptance among the younger generation as well as the exponential growth in popularity in car as well as in bike.
