Sat Nav

GPS refers to a bunch of satellites circling around the earth, since several decades, after the United States Government had positioned them in orbit. A GPS receiver communicates with these satellites, and indicates its present position accurately. The information, represented by a collection of co-ordinates guides the user to the destination. This type of receiver may be fitted to security systems or mobiles, while today’s smartphones have built-in receivers.
Sat Nav is actually the software that utilizes the signal from the GPS system. It picks up the co-ordinates given by the GPS, and unites it with a detailed map. For any given destination, the program computes a route, and continuously updates the GPS signal. Therefore, a satellite navigation system guides the user by giving one instruction after another, in a detailed manner.
Even certain digital cameras use the Global Positioning System to record the exact location of clicking a photograph. As these devices are gaining recognition and becoming more and more affordable, numerous products have flooded the market. Consumers have to consider essential elements, to discover the features that best suit them. Voice-based devices are particularly helpful, as they verbalize driving commands audibly. Price is also a big aspect, starting from a few dollars to a couple thousand dollars, depending upon the maker, as well as features of the gadget. A free map update of the system accompanies the purchase of the device from select manufacturers.
Both the systems can be found in various formats, and it is possible to get devices for cars, trucks, cyclists, athletes and runners. The display is the most important factor that determines the utility of these devices, with regard to size, readability and clarity. While purchasing a GPS device it is essential to observe the ease with which the menu system could be manipulated, readability under different lightings, battery life, and audible navigation. Traffic routing, text-to-speech functionality and Bluetooth capability are other crucial features to be taken into account prior to purchasing the device.
The most common brands of GPS equipment and Sat Nav equipment include TomTom and Garmin. Both the companies offer a various range of products. The Europe-based TomTom Company focuses on equipment for motor vehicles like cars and trucks. It also makes the required software for smartphones. The American-based Garmin Company concentrates on a myriad of products ranging from watches to aircrafts.
Travelers no more depend on stars or landmarks, as technology has advanced the modes of navigation from the traditional compass and paper maps, to today’s global positioning satellites. One has to literally consult these ultra-modern gadgets to find out the present location, as well as destination.

Generally known as Global Navigation satellite System (GNSS), the satellite navigation systems are the gadgets that provide autonomous geo-spatial positioning with global coverage. To begin with, we can have a look at the functioning of these devices that have more or less revolutionised the way we travel and communicate. A GNSS works by allowing small electronic receivers to determine the locations including longitude, latitude and altitude within a few meters with the support of time signals. These signals are transmitted along a line of sight by radio from satellites. In the present day, Global Positioning System (GPS) is the only fully functional global navigation satellite system. Satellite navigation devices were earlier used for defense purposes. But in the recent years they have become a part of daily life. In present days, these products are mostly used in vehicles. These devices help the users in identifying particular locations during long journeys to unknown destinations.

While purchasing a sat nav device, certain points have to be kept in mind. The user who opts for a device to be fitted in the vehicle should ensure that the device is user friendly – in terms of the interface it supports and the graphics & sound output it delivers. Devices having touch screen functionality should be preferred over others as scanning through endless pages of an instruction manual is a tough task while driving. A user who travels a lot would always need a map – and most of the sat nav devices come with one. However, before making the final purchase, the users have to ascertain the availability of the “right” coverage in the gadgets of his choice. This feature would be a great help in finding unknown destinations in the areas of one’s choice. In addition, potential users should go for a device that provides regular map updates of different countries.

Different sat nav devices deliver different sound outputs. It would be in the interest of the users to choose Sat Nav Devices that come with clear voice modules. Low or unclear voice levels would distract the attention of the users while driving, ands so the chances of accidents would increase. Also, care should be taken to select those devices that provide a choice in voices – this would ensure some degree of personalisation in these very useful accessories of our times.

Satellite Navigation systems offer geo-spatial positioning with wide global coverage. Scientifically known as Global Navigation Satellite System (GNSS), it ensures electronic receivers to inform about the longitude, latitude and altitude of the users. It tells you about the exact location where you are standing at that particular time. This is done with the time signals which are generally transmitted by satellite radios. The NAVSTAR Global Positioning System by the United States is the only operational GNSS right now. Russia is also marking its entry in the field with GLONASS. Galileo positioning system is scheduled to be operational by 2010. It is said to be the next generation GNSS by European Union.

The first Sat Nav device was installed by the US defense forces. Earlier, it was mainly used in the military applications but now they are used as car accessories and come pre-loaded with mobile phones. They broadcast the signal that informs about the position of the satellite and at the same time records the time of the transmitted signal. This detail is transmitted in a data format and is applied as code i.e. the time reference. They are now used with great ease and simplicity. Mostly used in cars, they are recognised as personal travel assistants.

They come with user-friendly features like turn-by-turn voice directions and highlighted points of interest, for example, petrol pumps, ATMs and restaurants. To avoid any error related to position, time and velocity, the satellite navigation receivers use Kalman filtering techniques. The sat Nav enabled devices are advantageous. They are used for varied navigational purposes like searching, surveying and in the field of geophysical sciences. Different well known brands such as Road Angel, Garmin and TomTom have introduced latest sat Nav gadgets with customer-friendly menus; wide touch screens and safety camera locations.

Satellite navigation systems always use radio time signals, which are transmitted by the satellites in order to enable mobile receivers on the ground to determine their exact location. It is due to the relatively clear line of site between the satellites and receivers on the ground. Which are combined with ever-improving electronics and allows satellite navigation systems to measure location to accuracies on the order of a few meters in real time. An early time the predecessor was used as a ground based Loran and Omega systems, which were used by terrestrial long wave radio transmitters instead of satellites. The first satellite navigation system was deployed by the US military in the 1960s.

In the present time the best necessary satellite navigation system is the Global Positioning System (GPS), which is nothing but a satellite-based navigation system, was made up by the help of a network of 24 satellites. It was placed into a fixed orbit by the U.S. Department of Defense. GPS satellites are powered by the solar energy. They have many backup batteries onboard, to keep them running in the event of a solar eclipse, when there’s no solar power. There are many Small rocket boosters on each satellite keep them flying in the correct path. Due to this GPS works in any weather conditions, also it is able to works anywhere in the world and 24 hours a day. GPS satellites circle the earth twice in a day, in a very calculative orbit and transmit signal information in to the earth. The GPS receivers take all this information and use triangulation to calculate the user’s exact location. 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 in a suitable way. GPS unit can calculate other information like speed, bearing, track, trip distance, distance to destination, sunrise and sunset time and more.

At the time of choosing any GPS devise you have to be careful about many things such as, Price, Features, Maps and Brand etc. Here is many satellite navigations product which available in the market in a very low cost such as: Garmin Nuvi 265W, Garmin Nuvi 255, TomTom ONE v4,TomTom XL Satellite Navigation System , Navman F45 Widescreen Satellite Navigation System etc.

The ease and simplicity of satellite navigation or Sat Nav devices have made them a welcome car accessories these days. The devices have made the stressful car journey to an unknown location a joyous occasion. These devices are equipped with features like turn-by-turn voice directions, highlighted points of interest (like ATMs, hotels, hospitals) which have made them a much sought after personal travel assistant.

The Sat Nav systems provide you autonomous geo-spatial positioning with global coverage. The satellite navigation receivers combine signals from multiple satellites and reduce errors by using techniques such as Kalman filtering to combine the constantly changing data into a single estimate for position, velocity and time. The Sat Nav systems, also known as Global Navigation Satellite Systems (GNSS) allow small electronic receivers to determine their location within a few meters using time signals transmitted by satellites. Based on their generations, the GNSS has been classified as GNSS -1 and GNSS -2.

Transit was the first satellite navigation system developed by the US military in 1960s. Satellite navigation is regarded as a force multiplier now-a-days. The system’s ability to reduce unintended casualties is of particular advantage in wars where public relations are an important aspect of warfare. The satellite navigation was originally intended for military use but has found applications in civilian use of late. Currently, the United States’ NAVSTAR Global Positioning System (GPS) is the only fully operational GNSS.

The Sat Nav systems have been put to a wide variety of use like navigation through hand-held devices fitted in cars, search and rescue operations, surveying and geophysical sciences. Several popular brands like Garmin, TomTom, Road Angel and Navman have launched their newest sat Nav devices with easy to use menus, safety camera locations and large touch screens. The systems have been developed so that they can be operated straight out the box and straight into the car.

Satellite navigation systems for your car used to be expensive accessories. But due to the rapid development of technology and rising competition, prices have slumped over the past few years so that almost everyone can afford sat navs nowadays.

The technology of satellite navigation systems resembles the one once used in submarines when they were on or near the surface and is the main global positioning system (GPS) of international military services. While originally developed and designed for military purpose in 1960-70 sat navs are now available for civilians, too. The principle is based on satellite signals determining the position of a sat nav receiver which is part of every in car sat nav system. Military devices have an astonishing accuracy with a maximum error of only one metre. Even though civil sat navs can’t keep up to this, they can easily position where about on a road the receiver is. However, the accuracy mainly depends on the number of satellites supporting a signal.

As a consequence of the rising popularity of sat nav systems for cars, the latest devices don’t only locate your position and give directions but include traffic, conjunctions warnings and even roadwork. Here, the recently launched TomTom Go 720 Traffic Edition has set a new milestone. It is able to receive live traffic updates via an RDS signal and takes them into consideration when calculating routing. It further suggests alternative directions if necessary and provides different routes depending on the day and time.

Nevertheless, with these additional features TomTom introduced a new generation of sat navs and thanks to an improved sensitivity to satellite signals almost no accuracy errors occur. It is expected that other leading manufacturers like Navman and Garmin will soon offer similar products with an equivalent feature. With a price range of over £200 the TomTom Go 720 Traffic Edition is still reasonably priced considering the technology. However, it might be worth being patient and waiting for a second generation as usually technical innovation comes along with troubles and often needs to be improved and adjusted.

Generally speaking, a sat nav is useful for every driver and especially for those who think that the philosophy of getting from A to B is more a game of pure chance than logical routing. If you tend to write directions down rapidly on a piece of paper, napkin or anything else that’s just within your reach then you should go for a reasonably priced satellite navigation system. This will not only save you money but also valuable time and you’ll reach your destination more relaxed.

Where would we be without our GPS systems? Many of us now have some kind of satellite navigation and as it eliminates stress and hassle, many more will look to Sat Nav to find their way.
