Consumer applications 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. Those devices may be assisted GPS or standalone (not network dependent) or both. Dedicated GPS navigation devices See also: automotive navigation systemand personal navigation assistant A variety of hand-held receivers A taxi in Kyoto, equipped with GPS navigation system 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. Their screens are small, and some do not show color, in part to save power. 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 to speech. Manufacturers include: TomTom products Garmin products Mio products Navigon products Magellan Navigation consumer products Mobile phones with GPS capability 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 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). Some phones with GPS capability work by assisted GPS (A-GPS) only, and do not function when out of range of their carrier's cell towers. Others can navigate worldwide with satellite GPS signals as a dedicated portable GPS receiver does, upgrading their operation to 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 double as a wireless modem for a laptop, while allowing GPS-navigation/localisation as well. 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. Other products including iPhone are used to provide similar services. Nokia gives Ovi Maps free on its smartphones and maps can be preloaded. Laptop PC GPS Various software companies have made available GPS road navigation software programs for in-vehicle use on laptop computers. Benefits of GPS on a laptop include larger map 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. Laptop computers allow for other uses beside GPS. GPS modules 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 or even a PDAs, 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. Some PCMCIA/ExpressCard GPS units also include a wireless modem. Devices usually do not come with preinstalled GPS navigation software, thus once purchased the user must install or write their own navigation software. As the user can choose which navigation 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 50-100 ). The software may include maps only for a particular region, or the entire world (if software such as Google Maps, Networks in Motion's AtlasBook mobile navigation platform, etc. is used). Examples of Bluetooth GPS devices are: Holux GPSlim236 For examples of USB GPS devices, see : Globalsat BU-303 GPS Holux? DeLorme Earthmate LT-40 with Street Atlas USA 2009 Haicom HI-204 III USB GPS Canmore GT-730F USB GPS Navman GPS e Series PlayStation Portable PSP-290 Examples of CF GPS devices are: Globalsat BC-337 SiRF Star III Compact Flash) Holux GR-271 Slim Compact Flash Haicom Hi-303III CompactFlash Examples of ExpressCard GPS devices with embedded modem are: Sony Ericsson ec400g Some hobbyists have also made some GPS devices and open-sourced the plans. An example is the Elektor GPS units. These are based around a SirFStar 3 chip and are comparable to their commercial counterparts. Commercial aviation Commercial aviation applications include GPS devices that calculate location and feed that information to large multi-input navigational computers for autopilot, course information and correction displays to the pilots, and course tracking and recording devices. Military Military applications include devices similar to consumer sport products for foot soldiers (commanders and regular soldiers), small vehicles and ships, and devices similar to commercial aviation applications for aircraft and missiles. More precisely, commanders and soldiers use the Commanders Digital Assistant and the Soldier Digital Assistant.
