Editing Navigator (section)

== Navigational equipment ==
The navigator is responsible for the maintenance of the ship's navigational equipment. U.S. Air Force navigators are responsible for troubleshooting problems of the navigation equipment while airborne, but the ground Maintenance personnel are ultimately responsible for the repair and upkeep of that aircraft's navigation system.

[[Boat]]s and [[ship]]s can use several Global Navigation Satellite Systems (GNSS) to navigate all of the world's lakes, seas and oceans. Maritime GNSS units include functions useful on water, such as "man overboard" (MOB) functions that allow instantly marking the location where a person has fallen overboard, which simplifies rescue efforts. GNSS may be connected to the ships [[self-steering gear]] and [[Chartplotter]]s using the [[NMEA 0183]] interface, and GNSS can also improve the security of shipping traffic by enabling [[Automatic Identification System|AIS]].
