GPS System - Overview

Global Positioning System known as GPS is a device, the system offers the most accurate and sophisticating navigation. They are generally used to find the destination gives you the right direction as you travel to unknown places. Were previously used by the people of defense to conduct military operations, weapon systems and missile tracking. In a short time have been used by people in all the ways to navigate, but their destination.

Intoday are used in aircraft, ships, trucks and cars for easy navigation of the route to your destination faster than before. The three main components of this navigation system is necessary, the satellites are satellites, monitoring stations and the GPS receiver. The treatment GPS receiver is a computing device that signals from the satellites and their location to be determined. The components include a GPS receiver antenna,Processors, an accurate clock and a display. Navigation systems are mounted and portable versions.

In the early models, the GPS receiver, the channels to receive signals from only four, now with the advancement of technology, the navigation systems installed have the opportunity to receive more channels than 15 These receivers were developed in area of models and models handheld or portable models. Travel often uses the portable model suitablebetter because they are compact and easy to wear. In addition to these components are some of the other features that are considered the cards, displays, voice directions, Wi-Fi and Bluetooth connectivity and entertainment options.

Before you buy a GPS device that is the main feature of note that the capacity of built-in hard drive. If the hard disk capacity is high, the device has a large memory, which helps you more cards and other data store. The GPS device must be largefor places to see clearly without any interference. The most important source to include a navigation system, card. GPS units that have been introduced recently has a pre-installed maps of your region if you need a site map of other places, a continuous or can be downloaded to the device from a CD.

Usually an SD card is used in navigation systems to improve the memory of the device to require more data. In the current situation, the need forNavigation system has been increased, which will help you achieve your goal correctly, even if you are new to the place. Some GPS systems are equipped with touch screen option, which helps the user to navigate easily. With all these outstanding features of the GPS only weighs a few ounces and fits in your pocket.

The advantages of a GPS system

The GPS is a device that is as high-tech map to find a place at any time. It can be purchased online or in local business. Since many vehicles are now equipped with one, several models are acceptable. In addition, the smaller they are - the more accurate they become. It works as a digital map for the driver to know the exact position / location and then provides the driver with different route options. It also tells the driver on all the neighborsCompanies.

With a GPS you can avoid traffic problems and will not be lost. This is a very important and should make the car. If you do not know the GPS system to acquire the guy who really have to some research. You must determine what type of system to which the work for you. Before you can restrict your search to determine a particular model or brand, how often is there to use it. Do you have a tight budget? If you do this,Do not worry, there is a wide range of models to choose from. You could always something cheap. On the other hand, if they are most often it is better to choose the most expensive.

Basically, there are various classifications of systems, you can choose. The four types are generally known car navigation system, portable external drive, the marine unit and the PDA / GPS hybrid. The most popular is the car's GPS system. It mayDetermine their exact position when on the road, especially if you do not have a map with you.

Some models have screens that maps and directions provided. Most GPS units are placed on the instrument panel and dashboard to your basis. Some cars do not have enough space and can not take this type of car GPS, the little GPS is the perfect solution.

When buying a system, you should always use the system functionality.And 'advisable, one that has more features than a good example is one that can give the exact location, simply enter the address or the indication of a specific location on the map.

There are GPS systems that can actually recognize the voice instructions. If you decide that you really want one, they should have a wireless network that the use of information processing in real time through the visual representation. Not all models offer visual site plans, if you travelalone. These visual representations make the information and tell you if you're on the right track.

If money is an issue when purchasing a GPS system, the market should not worry because with the long-range GPS systems, you will find one, the taste is not only fit your budget, but also yours. Thus, the price of a GPS typically in the range of $ 100 to $ 400 depending on the manufacturer.

GPS tracking system for navigation

GPS, satellite is also known as Global is a set of satellites orbiting the planet Earth. This system is able to send information about the location data and time on Earth. E 'possible for planets to tell the exact position of an object on the following areas of GPS tracking. Systems are widely distributed:

Location & Navigation
The GPS tracking system can be applied for the position location and navigationevery object on Earth. Initially, GPS was used to describe the navigation of aircraft and vessel positioning.

Tracking
With GPS systems, providing precise information on moving objects and people can be achieved in one day, the data provided by accurate and reliable.

Mapping
GPS tracking system is very useful for creating maps and models of various objects and with the GPS system, the task is easier today thanforever.

GPS tracking is the latest invention of technology to improve people's lives. Real-time GPS tracking systems in cars to be used to check the speed, and parents can help children, allows them to monitor their driving habits. This system can be used to ensure the safety of their children. It can be used to monitor the thefts at home. U.S. military uses these systems to determine directions and distancesDestinations.

This is already his important position in people's lives and feel more confident with the system. For it is the greatest invention of the system with data provided by age.Most time GPS is more accurate, but adverse weather conditions may object to the current position des

GPS clock system

When it comes to precise clocks in the GPS-system clock is one of the best. A GPS watch uses the Global Positioning Satellite System of the United States. Many of us are familiar with the Global Positioning Satellite, personal GPS receivers that we use every day to find addresses and places. This system of satellites around the earth, collect the data and can spread with 100% accuracy to 1 / 1000 of a second report includedand transmit data to various locations on Earth.

Once the signal is transmitted, it is then translated by the GPS receiver system and data sent to other recipients of the system, including wireless GPS clock. A GPS satellites transmit wireless takes information from multiple locations and then adjust for any errors or inconsistencies in time the right ones.

For a complete GPS c there is a wireless GPS receiver,and put on the roof of the building that collects time data from satellites and sends them to a master station, located inside the building. When the transmitter, the signal is then FM radio broadcasting signal to all other clocks Wireless GPS system. Each transmitter in the system can transmit up to 250,000 SF. This kind of super precise is often used in places such as schools, hospitals and industrial complexes.

Manythe receiver in use today heavily on data transmitted and transmissions from the GPS satellite system, and not through the radio station.

A GPS is a clock, consisting of one or more. Each has a transmitter, a GPS receiver and a system clock. This type of watch does not need input from you all and once it is connected to a power source and turned on he settled. It 'too easy even for the summer. Even if you happen to be aPower failure, the system is precise and wireless GPS clock automatically resets when the device is turned on again.

One of the most accurate clock system is a GPS wireless clock. GPS Wireless Clock reads the signals from satellites orbiting the planet for the accuracy and reliability of the nanosecond.

To find the key, the best system - GPS Ratings

GPS technology, while a wonderful invention, but not cheap, at least according to the unit is purchased. Specialized GPS systems can be close to $ 10,000, while those designed for consumers in general can be hundreds. Even simple GPS tracking systems used to exercise alone can cost more than $ 100. It 'so important to find out which is the best GPS before you actually make a purchase. This is possible through testing and evaluation> GPS reviews.

Online stores are the first type of websites offering GPS reviews and ratings. These assessments are usually from other people who have purchased the product on. You are a possibility, as well as product performance ratings data, and then are allowed to post a comment. The potential buyer will see how many "stars" was a product with the evaluation of other buyers. In the ideal case, the merit rating of this method is that buyers have no hidden agendaCreative, while the rating of the product. However, it is clear that certain views or not by customers or people who really do not have or use the product. You must take the time to read between the lines when a review is read or too good or too bad. Other sites, including those resulting from the production or dealers are design to make you buy their products. Apparently, it lacks the objectivity of their ratings might suggest.

Another good source for GPSTests on many comparison sites found online. This site contains reviews and comparisons GPS written by professionals. You may or may not comments from customers. When it comes to buying, online comparison sites typically do not offer products for sale directly by its URL. Most of them will be about one to affiliate links, which are published on the website for purchase. These are affiliate links visitors directly to the corresponding online-shop.

If youInternet searches, sometimes found written comments and ratings from customers that really like the product or hate it really. GPS reviews from this source also must be careful with tempered. Some authors have the time, these assessments, because they're trying to get visitors to buy from your affiliate links are being formed. Blogs, discuss GPS technology are another source of reviews, GPS products are used to compare. Others simply give advicefor the love of the function and design to try to ensure potential customers the best value for their money. While these sites may not contain as much information as the sites of professionalization of comparison can be a bit 'less overwhelming if you try to choose brands with only a couple of GPS.

If you intend to buy a GPS receiver, it would be wise for the first time a series of Web pages with credible reviews GPS. These may includeShopping, comparison sites or third-party sites created by individuals. Through these reviews one can get an idea of how effective and reliable, a GPS unit, without risking an investment.

Car Navigation System - How it works

Global Positioning System (GPS) is a navigation system developed by the Defence Department of UP. In 1978, the civilian use of this technology has been approved for the cars. If you reveal your current location on earth longitude and latitude form but also in the same position on the digital map. In this way, the calculation of distance and time are carried out quickly and easily.

In addition, automatic monitoring and automatic routing and re-routing capabilitiesThis technology greatly increases the safety features of cars and outdoor sports like hiking and hunting.

Surely you have experienced with map, compass and other navigation and mapping tools. How to find your location on the map, you must use three reference points. For correspondence manual, series fields or triangulation. With GPS receivers, the calculation is trilateration to determine position.

The GPS works with up to 24The satellites constantly orbiting the earth, each of which gives signals. To determine a specific place on Earth, the network GPS receiver used to receive and analyze signals via satellite. The receiver also takes careful note of the time during which the signals were received. With this information, the device will perform algorithmic calculations and analysis to determine the distance between the receiver and satellites.

In this account of datacurrent position of the beneficiary and its users based on reports trilateration to determine the distance by three points. These three points, the signals received by units of three or four satellites to determine a 2D position or perform the two-dimensional position determination. In this way, the recipient can expect that the absolute position of the three satellites, which are then set the path for the 3D position. The signals from the threeSatellites then provide a point of intersection, which is mainly used to check the accuracy of the positioning signals.

is set depending on the make or model, can provide very precise calculations or accurate calculations with deviation up to 12 meters. Technically, the precision of a portable GPS receiver that's exactly how the synchronization of atomic clocks in the system. The clock on the GPS is not atomic. The signalsexpressed by the fourth satellite receiver used to determine the site's internal clock and corrects any form of opposition.

Today there are many types of devices that are designed to meet the specific needs of navigation for different applications.

The GPS Fishfinder Adventure was developed for use on fishing and commercial fishing purposes and pleasant. Sonar With RSS, this allows portable assistant fisheries people chasing their biggeststart targeting a certain type of fish to temperature, time, feed water sonar and other parameters.

Aviation GPS was developed to assist pilots in navigating their artwork. Aviation units operate as a car GPS. your most important tasks in order to plan their users and to determine the shortest route to their destinations. In this way, aviation and land fuel economy is enormous and the time spent on the ruleTravel.

There are devices that are specifically designed to support the adventure of geocaching. Obviously portable receiver unit must be an essential tool for the safety of your daily commute, occasional trips and outdoor activities pleasant. this light, GPS applications in life was gone, well beyond its military roots, and in our daily lives.

WAAS - GPS-enabled system

WAAS (Wide Area Augmentation System) was developed by the Federal Aviation Administration to improve the global positioning system to complement the accuracy, integrity and availability. WAAS was originally to allow the plane to the airport, rely on GPS for all phases of flight, including precision approach in its coverage area. WAAS is usually greater than 1.0 meters laterally and 1.5 m vertically over much of the contiguous UnitedStates and in most of Canada and Alaska. This accuracy is provideing approaches with aircraft capable of precision flight safety and navigation for all conditions. WAAS integrity of the information no more than 3 seconds of invalid data by year allows the system to be considered safe by the FAA for instrument flight rules.

Although originally developed for aviation, not only from WAAS limited to aviation, all GPS receiver is able toThe WAAS signal reception in a position to benefit from the reduced data so that the accuracy of GPS position. In fact, a WAAS-enabled GPS receiver can also point the way into the lane the car is traveling through (provided that the program supports Maping directions, "Lane Assist"). Since the Wide Area Augmentation System quickly today is standard in the field of GPS, most new GPS receivers are WAAS capable. Only with suchConventinal GPS, WAAS makes the application will not be any additional costs or taxes. All you need is that the corrections WAAS-enabled GPS receiver will then be able to decrypt the data and can then apply. Currently, the service is limited WAAS in the United States, Canada, Alaska and Hawaii. Although independent of WAAS, Europe and Asia are working on their systems, some GPS fix. Europe has the Euro Geostationary NavigationOverlay Service Multi-Satellite Augmentation System (MSAS) (EGNOS) and Japan on their working conditions. "

How does the WAAS

WAAS uses a network of 25 land-based wide-area reference stations (WRS) in North America and Hawaii measure, to small variations in the Western Hemisphere GPS satellite signals. These precisely surveyed ground stations monitor and collect information on GPS signals and transmit their data tothree wide-area master stations (WMS). The WMS to create two different types of fixes: fast and slow. Fixes for bugs that change rapidly and are a major concern of the current positions of GPS satellites and clock errors. These corrections are independent of the user's location, which can immediately of any receiver in the WAAS coverage area may be applied. Corrections slow long-term estimates of the errors and ephemeric clock and ionosphereDelay of information.

Once these corrections are generated, the master sends Ground stations have two pairs of uplink stations (GUS), the transfer of messages of correction of a number of geostationary satellites to broadcast its correction data on the Earth. WAAS-enabled GPS receiver, then use this information to signial corrections to the original GPS, WAAS-enabled GPS receiver to give a more precise location. GPS receiver uses the informationeach GPS satellite to determine the transmission of their position and the current time. According to the GPS device, a GPS receiver needs only) of the signal received from 3 to 4 satellites (the 31 satellites currently transmiting a signal to the user civilan be able to calculate its position. In addition to GPS, WAAS - enabled GPS receiver can also download the geostationary WAAS satellite signal.

The two different types of correctionNews from the WAAS (fast and slow) are the type used by the GPS receiver. The rapid nature of the correction data includes the correct satellite position and clock data, calculations can his current position with GPS. The more time a approximate location of the fixed GPS receiver begins to use the corrections for the slow improvement of its accuracy. Contains data for Slow-to delay the ionosphere. If the GPS signal moves fromreach the satellite to the receiver through the ionosphere. The receiver calculates the position in which the signal penetrates the ionosphere and, if given a value of ionospheric delay for this place, it corrects the error that created the ionosphere. In contrast to the fast data transfer, the data are slow can not be updated regularly, because the ionospheric conditions do not change quickly. During the slow data can be updated every minute, as required, are only updated every twoMinutes and to be valid for a maximum of six minutes.

Limitations of the WAAS

(1) WAAS is currently only the U.S. and in most of Canada and Alaska, but will expand the system in other continents and countries.

(2) Since the WAAS geostationary satellite transmission means that travel less than 10 degrees above the horizon for positions in the north to 71.4.This means that aircraft can be used in areas of Alaska and northern Canada have difficulty maintaining a lock on the WAAS signal.

(3) For the calculation of a grid station ionospheric delay that a reference point and must choose between a satellite. The small number of satellites and ground stations, the number of points that can be calculated.

(4) Aircraft conducting WAAS approaches must be certified GPS receiver.
