| The worldwide Global Positioning System (GPS) | | | | six inches depending on the accuracy of the unit's |
| network is becoming more and more popular | | | | clock. While the GPS technology does not really |
| each day. Known as a useful tool for mapmaking, | | | | need a lot of space, the software that adds the |
| land surveying, commerce, and scientific uses, | | | | functionalities expected by the consumer, actually |
| GPS is now a widely used navigation aid world | | | | does. |
| wide. | | | | Uses Of GPS |
| The Global Positioning System (GPS) is the fully | | | | In the advanced modern world, GPS is mainly |
| functional Global Navigational Satellite System | | | | used in various daily life equipments including |
| which will help in determining the location, speed | | | | mobile phones and more popularly in cars. The |
| direction and time with the assistance of 24 | | | | military uses GPS technology to guide missiles, |
| medium earth orbit satellites. The GPS network | | | | track and control forces and facilities, and more. |
| consists of 24 navigation satellites, which orbit the | | | | Many newer vehicle models come with a GPS |
| planet at a height of approximately 12,000 miles. | | | | feature, which can be used to get customized |
| These satellites each orbit the earth twice every | | | | maps and directions from your current location, to |
| 24 hours, and they are set up in such a way that | | | | a specified location. Just like automobiles, many |
| they can send signals to any location on the | | | | boats and ships use GPS for navigation. On top of |
| planet, whether it be land or sea, and no matter | | | | that, GPS may be especially helpful during |
| how remote. | | | | darkness, fog, or other low visibility conditions. |
| The current GPS is divided into three major | | | | Hunters, wilderness explorers, and other outdoor |
| segments called space segment (SS), control | | | | sportsmen may use GPS for navigation purposes, |
| segment (CS), and user segment (US).It is the | | | | and / or to help find their way when lost. Many |
| navigation message broadcasted by GPS satellites | | | | surveyors use GPS units to survey and establish |
| that provides the time-of-day, GPS week number | | | | boundaries and other locations or markers. And |
| and satellite health information. | | | | for those who loves fishing, with a GPS unit you |
| How Does GPS Work? | | | | can just plot the points and you will have that |
| The software once created, gets improved by | | | | spot marked on your GPS so that you can go |
| getting smaller. GPS device requires a radio | | | | back to the same spot or just go find another |
| emitter and a clock to work. The emitter sends | | | | good spot and mark that down on the GPS. Or |
| the time of the clock to the satellite overhead. | | | | perhaps if you are in your boat and you are lost |
| The satellite then calculates the amount of time it | | | | you should have a plot that says home so that |
| took for the radio signal to reach them and then | | | | you can just activate home and it will send you in |
| figures the distance from that. Three or four | | | | that direction. The list of the benefits and |
| satellites compare their location and the time | | | | importance of GPS in our daily life grows as we |
| involved. They then show the location within about | | | | speak. |
