When more than three distances are involved, it may also be called multilateration, for emphasis. The point of interest is often around Earth (geopositioning).

thumb|Smartphone detecting an iBeacon transmitter iBeacon is a protocol developed by Apple and introduced at the Apple Worldwide Developers Conference in 2013. Various vendors have since made iBeacon-compatible hardware transmitters – typically called beacons – a class of Bluetooth Low Energy (BLE) devices that broadcast their identifier to nearby portable electronic devices. The technology enables smartphones, tablets and other devices to perform actions when in proximity to an iBeacon.

thumb|A Galileo (satellite navigation)|Galileo test environment Pseudolite in the [[Berchtesgaden Alps]] Pseudolite is a contraction of the term "pseudo-satellite," used to refer to something that is not a satellite which performs a function commonly in the domain of satellites. Pseudolites are most often small transceivers that are used to create a local, ground-based Global Positioning System (GPS) alternative. The range of each transceiver's signal is dependent on the power available to the unit.
