Localizer
From Wikipedia, the free encyclopedia
- A localizer is one component of an ILS or Instrument Landing System. The localizer usually provides runway centerline guidance to aircraft. In some cases a localizer is at an angle to the runway usually due to obstructions around the airport. Localizers also exist in stand-alone instrument approach installations and are not always part of an ILS or Instrument Landing System.
- A localizer is also a fictional device in the works of Vernor Vinge, such as A Deepness in the Sky. These are tiny devices, powered by microwave pulses, which can contain a simple processor, sensors, and short-range communications. Vinge explores how wireless mesh networking of these simple devices in a mobile ad-hoc network can be put to use in ways quite different from traditional computer networks.
