Geopositioning uses various visual and electronic methods including position lines and position circles, celestial navigation, radio navigation, radio and WiFi positioning systems, and the use of satellite navigation systems. The calculation requires measurements or observations of distances or angles to reference points whose positions are known.
The distinction must be made between a singular geographic information system, which is a single installation of software and data for a particular use, along with associated hardware, staff, and institutions (e.g., the GIS for a particular city government); and GIS software, a general-purpose application program that is intended to be used in ...
A local positioning system (LPS) is a navigation system that provides location information in all weather, anywhere within the coverage of the network, where there is an unobstructed line of sight to three or more signaling beacons of which the exact position on Earth is known.
The Global Positioning System (GPS), originally Navstar GPS, [2] is a satellite-based radio navigation system owned by the United States Space Force and operated by Mission Delta 31. [ 3 ] [ 4 ] It is one of the global navigation satellite systems (GNSS) that provide geolocation and time information to a GPS receiver anywhere on or near the ...
Location-based service (LBS) is a general term denoting software services which use geographic data and information to provide services or information to users. [1] LBS can be used in a variety of contexts, such as health, indoor object search, [2] entertainment, [3] work, personal life, etc. [4] Commonly used examples of location-based services include navigation software, social networking ...
The geographical location data used in geotagging can, in almost every case, be derived from the global positioning system, and based on a latitude/longitude-coordinate system that presents each location on the earth from 180° west through 180° east along the Equator and 90° north through 90° south along the prime meridian.

Wi-Fi positioning system (WPS, WiPS or WFPS) is a geolocation system that uses the characteristics of nearby Wi‑Fi access points to discover where a device is located. [1]It is used where satellite navigation such as GPS is inadequate due to various causes including multipath and signal blockage indoors, or where acquiring a satellite fix would take too long. [2]
