19 devices usually do not come with pre-installed gps navigation software, thus, once purchased, the user must install or write their own software. As the user can choose which software to use, it can be better matched to their personal taste. It is very common for a pc-based gps receiver to come bundled with a navigation software suite. Also, gps modules are significantly cheaper than complete stand-alone systems (around 50 to 100). The software may include maps only for a particular region, or the entire world, if software such as google maps are used. Some hobbyists have also made some gps devices and open-sourced the plans. Examples include the Elektor gps units.

The phone downloads a file to help it locate gps satellites more quickly and reduce the time to first fix. 14 Palm, pocket and laptop pc edit for manufacturers of commercial software, see gps_navigation_software Software. Further information: Comparison of gps software software companies have made available gps navigation software programs for in-vehicle use on laptop computers. 15 Benefits of gps on a laptop include larger map biography overview, ability to use the keyboard to control gps functions, and some gps software for laptops offers advanced trip-planning features not available on other platforms, such as midway stops, capability of finding alternative scenic routes. Palms 16 and Pocket pc 's can also be equipped with gps navigation. 17 A pocket pc differs from a dedicated navigation device as it has an own operating system and can also run other applications. Gps modules edit a modern sirfstariii chip based 20-channel gps receiver with waas/egnos support Other gps devices need to be connected to a computer in order to work. This computer can be a home computer, laptop, pda, digital camera, or smartphones. Depending on the type of computer and available connectors, connections can be made through a serial or usb cable, as well as Bluetooth, compactFlash, sd, pcmcia and the newer ExpressCard. 18 Some pcmcia/ExpressCard gps units also include a wireless modem.

Other products including iPhone are used to provide similar services. Nokia gives here maps free on mobile operating systems: Windows Phone 8, Android, sailfish os and Firefoxos, but excluding ios. Maps can be preloaded onto the device. According to market research from the independent analyst firm Berg Insight, the sales of gps-enabled gsm/wcdma handsets was 150 million units in 2009, 12 while only 40 million separate gps receivers were sold. 13 gps navigation applications for mobile phones include write on-line (e.g. Waze, google maps navigation, apple maps ) and off-line (e.g. Igo for Android, maverick and here for Windows Phone) navigation applications. Google maps navigation, which is included with Android, means most smartphone users only need their phone to have a personal navigation assistant. Many Android smartphones have an additional gps feature, called Extended Prediction Orbit (EPO).

Some phones using assisted gps (a-gps) function poorly when out of range of their carrier's cell towers. Others can navigate worldwide with satellite gps signals as well as a dedicated portable gps receiver does, upgrading their operation to first a-gps mode when in range. Still others have a hybrid positioning system that can use other signals when gps signals are inadequate. More bespoke solutions also exist for smartphones with inbuilt gps capabilities. Some such phones can use tethering to mini double as a wireless modem for a laptop, while allowing gps-navigation/localisation as well. 11 One such example is marketed by verizon Wireless in the United States, and is called vz navigator. The system uses gpsOne technology to determine the location, and then uses the mobile phone's data connection to download maps and calculate navigational routes.

Their screens are small, and some do not show color, in part to save power. Some use transflective liquid-crystal displays, allowing use in bright sunlight. Cases are rugged and some are water resistant. Other receivers, often called mobile are intended primarily for use in a car, but have a small rechargeable internal battery that can power them for an hour or two away from the car. Special purpose devices for use in a car may be permanently installed and depend entirely on the automotive electrical system. The pre-installed embedded software of early receivers did not display maps; 21st century ones commonly show interactive street maps (of certain regions) that may also show points of interest, route information and step-by-step routing directions, often in spoken form with a feature called " text. Manufacturers include: Mobile phones with gps capability edit further information: Comparison of gps software due in part to regulations encouraging mobile phone tracking, including E911, the majority of gps receivers are built into mobile telephones, with varying degrees of coverage and user accessibility. Commercial navigation software is available for most 21st-century smartphones as well 10 as some java -enabled phones that allows them to use an internal or external gps receiver (in the latter case, connecting via serial or Bluetooth ).

High Sensitivity gps can provide positioning in many but not all indoor locations. Signals are either heavily attenuated by the building materials or reflected as in multipath. Given that High Sensitivity gps receivers may be up to 30 dB more sensitive, this is sufficient to track through 3 layers of dry bricks, or up to 20 cm (8 inches) of steel reinforced concrete for example. Citation needed Examples of high sensitivity receiver chips include sirfstariii and Mediatek s mtk. 9 Consumer applications edit consumer gps navigation devices include: Dedicated gps navigation devices gps modules that need to be connected to a computer to be used gps loggers that record trip information for download.

Such gps tracking is useful for trailblazing, mapping by hikers and cyclists, and the production of geocoded photographs. Converged devices, including gps phones and gps cameras, in which gps is a feature rather than the main purpose of the device. The majority of gps devices are now converged devices, and may use assisted gps or standalone (not network dependent) or both. The vulnerability of consumer gps to radio frequency interference from planned wireless data services is controversial. Dedicated gps navigation devices edit see also: automotive navigation system and personal navigation assistant Hand-held receivers A taxi equipped business with gps dedicated devices have various degrees of mobility. Hand-held, outdoor, or sport receivers have replaceable batteries that can run them for several hours, making them suitable for hiking, bicycle touring and other activities far from an electric power source.

While the American gps was the first satellite navigation system to be deployed on a fully global scale, and to be made available for commercial use, this is not the only system of its type. Due to military and other concerns, similar global or regional systems have been, or will soon be deployed by russia, the european Union, China, india, and Japan. Sensitivity edit gps devices vary in sensitivity, speed, vulnerability to multipath propagation, and other performance parameters. High Sensitivity gps receivers use large banks of correlators clarification needed citation needed and digital signal processing to search for gps signals very quickly. This results in very fast times to first fix when the signals are at their normal levels, for example outdoors. When gps signals are weak, for example indoors, the extra processing power can be used to integrate weak signals to the point where they can be used to provide a position or timing solution.

Gps signals are already very weak when they arrive at the earths surface. The gps satellites only transmit 27 W (14.3 dBW) from a distance of 20,200 km in orbit above the earth. By the time the signals arrive at the user's receiver, they are typically as weak as 160 dbw, equivalent to one tenth of a million-billionth of a watt (100 attowatts). This is well below the thermal noise level in its bandwidth. Outdoors, gps signals are typically around the 155 dBW level (125 dBm ). Conventional gps receivers integrate the received gps signals for the same amount of time as the duration of a complete C/A code cycle which is. This results in the ability to acquire and track signals down to around the 160 dBW level. High Sensitivity gps receivers are able to integrate the incoming signals for up to 1,000 times longer than this and therefore acquire signals up to 1,000 times weaker, resulting in an integration gain of 30 dB. A good High Sensitivity gps receiver can acquire signals down to 185 dbw, and tracking can be continued down to levels approaching 190 dBW.

5 In 1991, mitsubishi introduced gps car navigation on the mitsubishi debonair (mmcs: Mitsubishi multi communication System). 6 In 1997, a navigation system using Differential gps was developed as a factory-installed option on the toyota Prius. 7 As gps navigation systems became more and more widespread and popular, the pricing of such systems began to fall, and their widespread availability steadily increased. Also, several additional manufacturers of these systems, such as Garmin (1991 benefon (1999 mio (2002) and TomTom (2002) entered the market. Mitac mio 168 was the first first PocketPC to contain a built-in gps receiver. 8 Benefon's 1999 entry into the market also presented users with the world's first phone based gps navigation system. Later, as smartphone technology developed, a gps chip eventually became standard equipment for most smartphones. To date, ever more popular gps navigation systems and devices continue to proliferate with newly developed software and hardware applications. It has been incorporated, for example, into cameras.

In 1973, the us military began to plan for a reworded comprehensive worldwide navigational system which eventually became known as the gps (global positioning system). In 1983, in the wake of the tragedy of the downing of the korean Airlines Flight 007, an aircraft which was shot down while in soviet airspace due to a navigational error, President reagan made the navigation capabilities of the existing military gps system available. However, civilian use was initially only a slightly degraded " Selective availability " positioning signal. This new availability of the us military gps system for civilian use required a certain technical collaboration with the private sector for some time, before it could become a commercial reality. In 1989, magellan navigation Inc. Unveiled its Magellan nav 1000, the worlds first commercial handheld gps receiver. These units initially sold for approximately us2,900 each. In 2000, the Clinton administration removed the military use signal restrictions, thus providing full commercial access to the us gps satellite system. In 1990, mazda 's Eunos Cosmo was the first production car in the world with a built-in gps navigation system.

system (. Glonass ) was developed contemporaneously with gps, but suffered from incomplete coverage of the globe until the mid-2000s. 3, glonass can be added to gps devices to make more satellites available and enabling positions to be fixed more quickly and accurately, to within 2 meters. 4, contents, automotive navigation system edit, using the gps information and subject to the sophistication of installed gps software, a gps device used as an automobile navigation system may be used in a number of contexts, including: maps, including street maps, displayed in human readable. Gps devices may be able to indicate: the roads or paths available, traffic congestion and alternative routes, roads or paths that might be taken to get to the destination, if some roads are busy (now or historically) the best route to take, the location. History edit further information: Global Positioning System  History As with many other technological breakthroughs of the latter 20th century, the modern gps system can reasonably be argued to be a direct outcome of the cold War of the latter 20th century. The multibillion-dollar expense of the program was initially justified by military interest. In 1960, the us navy put into service its Transit satellite based navigation system to aid in ship navigation. Between 19, as the benefits were been shown, the us military consistently improved and refined its satellite navigation technology and satellite system.

1, the gps was originally developed for use by the United States military, but in the 1980s, the United States government allowed the system to be used for civilian purposes. Though the gps satellite data is free and works anywhere in the world, the gps device and the associated software must be bought or rented. A gps device can retrieve from the gps system location and time information in all weather conditions, anywhere on or near the earth. A gps reception requires an unobstructed line of sight to four or more gps satellites, 2 and is subject to poor satellite signal conditions. In exceptionally poor signal conditions, for example in urban areas, satellite signals may exhibit multipath propagation where signals bounce off structures, or are weakened by meteorological conditions. Obstructed assignment lines of sight may arise from a tree canopy or inside a structure, such as in a building, garage or tunnel. Today, most standalone gps receivers are used in automobiles. The gps capability of smartphones may use assisted gps (a-gps) technology, which can use the base station or cell towers to provide the device location tracking capability, especially when gps signals are poor or unavailable.
