	Maidenhead Locator System - Wikipedia, the free encyclopedia
		The Maidenhead Locator System or Maidenhead Grid squares is a scheme used by amateur radio operators for identifying positions on the Earth.
		It was proposed by the British radio amateur Dr. John Morris (G4ANB), and later adopted by a group of VHF managers, meeting in Maidenhead, England in 1980, to supplant the older QRA locator system with one that would be usable outside of Europe.
		A Maidenhead locator represents a position on the Earth based on latitude and longitude.

		The "Maidenhead QTH Locator System" is the official QTH locator system adopted by the IARU (International Amateur Radio Union) and replaces the old "QRA Locator System".
		The new system is used primarily by the Amateur Radio Service and uniquely defines any given point on the surface of the globe to within an area of 5 minutes of longitude by 2.5 minutes of latitude.
		The main disadvantage of the old QRA Locator System was that several points on the earth's surface had the same reference.

		The Grid Locator overlays show the IARU Grid Locator system, used to identify positions by Radio Amateurs on HF and VHF, and in some contests and operating awards.
		First proposed at a conference in Maidenhead, England in 1980 (and hence sometimes called Maidenhead Locators), grid squares allow three levels of precision (two, four or six character) to define a station's latitude and longitude.
		Using this system, a station's location is thus identified to within better than 5.6 nautical miles anywhere on the surface of the Earth.

		For accuracy down to only a few km, locator squares can be further subdivided into 24 x 24 sub-squares by adding two extra digits from AA to XX.
		The locator field is represented by QF, the locator square by 23 and the sub-square by FF.

		An instrument of the Maidenhead Locator System (named after the town outside London where it was first conceived by a meeting of European VHF managers in 1980), a grid square measures 1° latitude by 2° longitude and measures approximately 70 × 100 miles in the continental US.
		The actual size of a grid square depends on the particular location, as the 1° of longitude represents different distances at different latitudes; longitude lines are closer together at the Earth's poles than at the equator.
		The other system is the universal transverse mercator (UTM) system that consists of squares 1 kilometer on a side.

		You can determine grid locators in North America using the tables given on pages 49-50 of the January 1983 issue of QST or for South America using the tables given on pages 52-53 of the October 1983 issue of QST.
		If you are given a grid locator, you will be able to tell approximately where that station is. For more precise location information, the Maidenhead system also allows an optional two characters to be appended to the basic grid locator.
		This program will work for the entire world, although if you are not in North America, you may want to change the defaults (North latitude and West longitude) set in lines 230 and 330 of the BASIC program.

		Radio amateurs use the Maidenhead Locator System as an alternative to the classical latitude/longitude coordinate system to indicate their position.
		It divides the world up into grid squares, identified by a four-character or six-character grid square locator, enabling radio amateurs to pass on their position during a contact to fellow hams fairly accurately using only 6 digits.

		The Locator eg IO90IV or IO90IV58 is a locator system based on Lat / Long that allows any location in the World to be specified by an alphnumeric code.
		Originally invented by Radio Amateurs the Locator system has been seen in several other areas where it is often referred to as the Maidenhead locator (its original name, so called as its inventor lived there).
		So far 10 digit locators have only been seen on certain up-market Global Positioning System receivers as the accuracy of 18m is rarely needed or even obtainable.

		The QTH Locator System is primarily used on the VHF bands, the six character groups forming part of contest exchanges and it is also often used during normal QSOs to pin-point a station's location.
		Calculations made from latitude and longitude values or National Grid References will be accurate, but conversions from locators or WAB squares relate to the centres of the squares and could, therefore, be subject to small errors depending upon the precise position of a given point within the square.
		The fifth map shows the internationally agreed zoning system devised by the ITU (International Telecommunications Union, which is an Agency of the United Nations) and is used by all radio broadcasting and communication Services, including the Amateur Radio Service.

		This locator JN48LW showed that we are only a few kilometres away from 49°N and 9°E. Thus, for the school year 1999/2000 we planned to locate the Confluence 49N 9E.
		That means, it is likewise not located at the 49N 9E confluence, as defined by the German "Potsdam" geodetic system.
		The reason for this misplacement may be the influence of "Selective availability" being still in use during the first months of 2000, or that it has been placed intentionally beside a long-distance hiking trail.
