GPS tracking unit in the context of "Smartphones"

A smartphone is a mobile device that combines the functionality of a traditional mobile phone with advanced computing capabilities. It typically has a touchscreen interface, allowing users to access a wide range of applications and services, such as web browsing, email, and social media, as well as multimedia playback and streaming. Smartphones have built-in cameras, GPS navigation, and support for various communication methods, including voice calls, text messaging, and internet-based messaging apps. Smartphones are distinguished from older-design feature phones by their more advanced hardware capabilities and extensive mobile operating systems, access to the internet, business applications, mobile payments, and multimedia functionality, including music, video, gaming, radio, and television.

Smartphones typically feature metal–oxide–semiconductor (MOS) integrated circuit (IC) chips, various sensors, and support for multiple wireless communication protocols. Examples of smartphone sensors include accelerometers, barometers, gyroscopes, and magnetometers; they can be used by both pre-installed and third-party software to enhance functionality. Wireless communication standards supported by smartphones include Wi-Fi, Bluetooth, Hotspots and satellite navigation. By the mid-2020s, manufacturers began integrating satellite messaging and emergency services, expanding their utility in remote areas without reliable cellular coverage. Smartphones have largely replaced personal digital assistant (PDA) devices, handheld/palm-sized PCs, portable media players (PMP), point-and-shoot cameras, camcorders, and, to a lesser extent, handheld video game consoles, e-reader devices, pocket calculators, and GPS tracking units.

Electronic tagging is a form of surveillance that uses an electronic device affixed to a person to monitor their location or physiological state. It is a specific application of asset tracking technology where the "asset" being monitored is a person.

In some jurisdictions, an electronic tag fitted above the ankle is used for individuals as part of their bail or probation conditions. It is also used in healthcare settings and in immigration contexts. Electronic tagging can be used in combination with a GPS tracking unit for wide-area monitoring, but for short-range monitoring of a person, radio frequency technology is often used.

OpenStreetMap (OSM) is a map database maintained by a community of volunteers via open collaboration. Contributors collect data from surveys, trace from aerial photo imagery or satellite imagery, and import from other freely licensed geodata sources. OpenStreetMap is freely licensed under the Open Database License and is commonly used to make electronic maps, inform turn-by-turn navigation, and assist in humanitarian aid and data visualisation. OpenStreetMap uses its own data model to store geographical features which can then be exported into other GIS file formats. The OpenStreetMap website itself is an online map, geodata search engine, and editor.

OpenStreetMap was created by Steve Coast in response to the Ordnance Survey, the United Kingdom's national mapping agency, failing to release its data to the public under free licences in 2004. Initially, maps in OSM were created only via GPS traces, but it was quickly populated by importing public domain geographical data such as the U.S. TIGER and by tracing imagery as permitted by source. OpenStreetMap's adoption was accelerated by the development of supporting software and applications and Google Maps' 2012 introduction of pricing.

Vehicle location data is the big data collection of vehicle locations, including automatic vehicle location data, a core feature of any vehicle tracking system. This usually includes times and often photographs as well, a practice known as video telematics. The process of collecting this data from remote assets via telemetry is a core component of telematics, often managed by a telematic control unit. Its application in the commercial sector forms the basis of fleet digitalization and is central to any fleet telematics system.

Common methods of data collection include automatic number plate recognition from cameras, such as a Dashcam, and radio-frequency identification (RFID) from transponders. In commercial contexts, a dedicated GPS tracking unit is often used for this purpose, forming part of a wider tracking system. Databases of this information are maintained by both government and private entities. For businesses, this data is essential for fleet management tasks like Track and trace, enabling vehicle repossession, and consumer profiling through methods like Driver scoring. Government databases have been subjected to legal orders for location data, and access may be granted in both criminal and civil cases.

In the automotive industry, a telematic control unit (TCU) is an embedded system that connects a vehicle to the internet and serves as a hub for external wireless communications. It enables modern connected vehicle services, including telematics, fleet management, and V2X (Vehicle-to-Everything) communication. The TCU's primary functions are to collect data from the vehicle's internal systems, a process known as telemetry, and to facilitate two-way communication with cloud-based services. While the term typically refers to a factory-installed (OEM) unit, its functionality is also available through third-party aftermarket telematic devices that can be installed in vehicles not originally equipped with an OEM system.

Telematics is an interdisciplinary field encompassing telecommunications, vehicular technologies (road transport, road safety, etc., as part of Intelligent transportation systems), electrical engineering (sensors, instrumentation, wireless communications, etc.), and computer science (multimedia, Internet, etc.). Telematics can involve any of the following:

• The technology of sending, receiving, and storing information using telecommunication devices, such as a Telematic control unit, to control remote objects
• The integrated use of telecommunications and informatics for application in vehicles and to control vehicles on the move
• Global navigation satellite system technology (most commonly GPS) integrated with computers and mobile communications technology in automotive navigation systems, often using a GPS tracking unit
• (Most narrowly) The use of such systems within road vehicles (also called vehicle telematics)
