It provides continuous and timing information any where in the world under any whether conditions .because it serves an unlimited number of users it is being used for security reasons.
How GPS works?
The main concept behind in GPS calculating is distance between the satellites and the receiver. Where as satellites say us accurately about the orbits by telecasting information then receivers receives the data to alter their locations. Working with GPS is if the persons know accurate distance to a satellite in space, if the person knows some where on the earth surface which consists of an imaginary sphere with a radius that which equals to distance of satellite radius .if the person knows accurate distance between two satellites then the person easily know that where he positioned on the surface that which the both spheres interact
How to use GPS in mobiles phones?
Buying of GPS hardware and software is totally costly .Today system has been changed through help of cellular service providers.
Locating the people in emergency
In case if you need to locate a person immediately by using cell phone GPS system can trace him easily. Where the person uses right network by connecting good mobile phone.

GPS technology requires three segments
Normally in a day 24 GPS satellites orbit surrounds the earth two times in a day spectrum .which they travel at least 7000 miles per hour and which rotates around earth surface nearly 12000 miles .with these satellites that spaced so that's why a GPS receiver can receive signals from any part of the universe which it contains at least four of them.
Which GPS satellite averages transmits radio signals to the earth surface .the information regarding GPS satellites contain.
Which sends the information from a particular satellite
It does not considers whether satellite is working or not
The signals which satellite sends the date and time.
Where as signals can pass through cloud, plastic or glass. where the signal power attenuates such as building crossings and some times signals cannot travel through materials such as lot materials or things that contains water.
The solar energy which is powered by GPS satellites when the solar energy does not exist for e.g.: it utilizes earth's shadow that which it acts back up batteries in a continuous manner. the GPS satellites is builder up at least 10 years which the Department of defence monitors and recharges the satellites to updated new features or technology continues to move smoothly to over come the situation.
Control segment consists of
It contains three categories
master control station
Normally six unmanned monitor station placed around the universe which it constantly controls and receives the data from the GPS satellite and then transforms the orbital and clock data to the master control station.
MCS is placed near Colorado Springs in Colorado .which it averages receives GPS satellite orbital and clock data from monitor station. According to correction in the information as necessary which the MCS is control and transform the data to the GPS satellite by utilizing the ground antennas.
Which it receives clock data and correlated orbit from ground antennas through the MCS and which transforms the data to the particular satellites.
GPS receiver is consisted to user segment through the GPS. which receiver gather and transforms signals from the GPS satellites that are in located and which that data has to calculated and which the location ,place and time .which the GPS receiver could not transmit any data back to the satellites.
Putting GPS to work?
The most important application in GPS is finding of a position or locating a place .it is the first positioning system which it is offer highly precise information for any object in any whether condition.
Which it helps to locate the point's nation wide geodetic network .it is used for surveying the projects.
GPS has actually designed to give navigation data for ships and planes. It's useful in water and it also provides useful information on land and air. By using navigation technology which it cal cutes accurately where you are.
By using the gps commercial business person can deter mine their fishing holes without searching into wrong places.
Tracking is the process that which controls it as it moves along. By using this technology we can trace the vehicle easily, it helpful in saving accident case.
Police, ambulance and fire departments are implementing this system know automatic vehicle location .for providing better service to the people.
By using this technology surveyor can complete with in day before the days it takes one week or more
It is the mapping world
It is sort of resources things like roads, routes and city streets.
It is mostly known for location, navigation, mapping and tracking. Time intervals, frequently and precise time. It is most power full one and accurate is more powerful .GPS systems develops our watches to synchronize easily and reliable. Time makes the world to keep in a schedule manner. Mainly all the companies, televisionstation, communications systems mainly depend and benefits from the precise time.
Which the mobile messaging is evolved through SMS text message that which introduces MMS(multimedia messaging device0.in the olden days such method is utilized to point to point communication. which the messages are normally shown on hand set with a minimum sized screen. how ever this type of situation is not attachable to broad cast real time SMS/MMS message to a public. To utilizes the accurate and advertisement that which related with java web services techonolgy,to develop more visualizing SMS and mms system. The concept of combining both SMS and mms from GPRS /GSM into a remote screen
It is the abbreviation that states short message service .The meaning of SMS is to send a text message trough the mobile device to another device.
