Vlsi Based Accident Information and Car Security System

If they do not, but are within the acceptable margin of error of ±20√4=±40’’, each angle is corrected to create a sum of 360˚. For this project, the angles added to 360˚ 00’ 10’’. After each angle is corrected, angle 412 is 78˚31’03’’, angle 123 is 99˚01’23’’, angle 234 is 92˚32’21’’, and angle 341 is 89˚53’13’’. After using the Total Station, the Auto level is used to measure the elevations of each point. The known elevation outside of Powell is 380’. The Auto level is placed between each point to measure the backsight and foresight. Once all the points are measured, all the backsights and foresights can be measured with the difference taken to find the error. With this project, the error was -0.128’. Next, the pacing between each point must be taken to find the correction for each elevation with the equation, (distance from known elevation/total level network distance) X total error. The total pacing for the project is 235 steps with a pace of 2.31 feet per step. After the corrections, point 4 is 379.384’, point 3 is 378.182’, point 2 is 379.093’, and point 1 is 379.645’. A transit is used to find the true north from the magnetic

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 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

A cell phone is an electronic device used for the mobile telecommunication i.e. mobile telephony, data transmission and text messaging. It is used over a cellular network of specialized base stations. It differs from cordless telephones, which offers telephony service only within a limited range i.e. within a home or an office. As the time passes it offers more and more advance features. A society is a social, economical or industrial infrastructure,

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.

Upon a request from a subscriber for location information about an MS, the service provider will contact a location control center querying it for the coordinates of the MS. This subscriber could be a commercial subscriber desiring to track a mobile device or a PSAP trying to answer an E-911 call. The location control center will gather information required to compute the MS’s location. This information could be parameters such as received signal strength, BTS ID, TOA of signals, and so on that we discuss later. Depending on past information about the MS, a set of BS’s could be used to page the MS, and directly or indirectly obtain the location parameters. These are sometimes called Geolocation base stations (GBSs). Once this information is collected, the location control center can determine the location of the mobile with certain accuracy and convey this information to the service provider. The service provider will then use this information to visually display the MS’s location to the subscriber. Sometimes the subscriber could be the MS itself, in which case the messaging and

GPS satellites are powered by solar energy. They have backup batteries onboard to keep them running in the event of a solar eclipse, when there’s no solar power. Small rocket boosters on each satellite help them keep flying in the correct path.

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.

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!

The Global Positioning System (GPS) is used by an almost endless amount of people and professions. Although originally designed for

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.

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

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