Ground Based Air Navigation Support Structures
Managed By: Icon Here Navaid Searchers
Widely unknown to the broader public, there are thousands of stations all over the world that help airplanes to safely find their destination. This is the place to record them.
Expanded Description:

A standard VOR in Nieburg, Germany

Air navigation has gone a long way since the first motorized flights. With the growing number of airplanes, many navigational technologies have been invented, introduced, and later replaced with more advanced ones. Most passengers entering a plane have no idea how many ground based structures there are, that are (or were) involved in air navigation.

NDB transmitter Jersey West

We want to collect information about those structures, active or abandoned, no matter what technology used, as long as the explicit purpose is air navigation. Some of those systems are located in restricted areas, often airport grounds, but many are miles away, enclosed within small fences. Please, limit your contributions to locations that can be legally accessed and photographed! The viewpoint should be close enough to clearly identify some details of the structure.

Concrete Arrow near Transcontinental Air Mail Route Beacon 37A, St. George, Utah

In the first years of air travel there was only visual flight, but even then, facilities were built to help pilots find their way. Examples of this era are the concrete arrows in the American midwest and lit beacons, some of which have been preserved and still exist. The first radio navigation systems were introduced as early as 1907. Many different systems have been in use since then. Common current systems are VOR and NDB. Some of their precursors were LFR, VAR and many more. Today, there is a shift towards satellite based navigation, but ground based systems will be around for many years, remaining active as backup systems.

We want to neither bore nor frighten you with hundreds of acronyms. You do not need to know them and you do not have to be an expert to participate. But you will have to prove that your submission is indeed an object that is or was primarily used for air navigation. For this purpose, you must provide a link to a website at which this station is listed. Some good reference sources are:


Aerodrome Beacons Ground-based Arrows

Radar stations are not used for air navigation by the pilots directly, so we are not going to accept them here. We are not looking for aircraft warning lights either.

Short Glossary (More information about the topic can be found e.g. here.)

Airway beacon: a rotating light assembly mounted atop a tower (created starting 1923, replaced by LFR after 1929, mostly deactivated by 1973; in Montana there are some remaining in service)
ADF: automatic direction finder (the on-board adjunct to NDBs)
LFR: low-frequency radio range (the main system in the 1930s and 1940s)
NDB: non-directional (radio) beacon (first deployed in the 1930s, still a standard system)
VOR: VHF omni directional radio range (invented 1937, deployed in 1946, still the standard system today with about 3000 stations worldwide)

Instructions for Posting a Ground Based Air Navigation Support Structures Waymark:
COORDINATES must be obtained by a personal visit to the site and should be taken as close to the structure as legally possible.

PHOTOS: Please provide at least two photos, one close up photo of the structure and one photo which shows it in its surroundings. More pictures are always welcome.

DESCRIPTION: Provide as much information as possible - dates, historical significance, current status, etc. A long description is required and it must cover the specific structure of the submission. A general text about the system and how it works is not what we are looking for here, but can be added, if desired.

WAYMARK NAME FORMAT: The name of the waymark MUST follow this format: Name of the structure (including the type acronym or name, such as "VOR", "NDB", "Beacon", etc.) - City, State/Province or Country. If it is not within a city or town, then please use another regional designation such as county, parish, municipal division, borough - whatever best identifies the location.

SPECIAL NOTE: While the details outlined in our category description, and the requirements listed in the posting instructions, cover the MINIMUM elements and standards for all waymarks in this category, each waymark will also be evaluated by a volunteer reviewer for overall quality and appropriateness. If a reviewer deems that there are deficiencies in some aspect of the waymark, the waymark may be either declined or accepted with request for changes and/or additions in either content or format.

Each waymark will be evaluated on its own merits. We will endeavor to be reasonable and flexible while maintaining the quality standards for the category. If there is a disagreement, try to work it out with the evaluating officer, or appeal to the group leader, but we reserve the right to accept or decline a waymark based on our best judgement.

LANGUAGE NOTE: We recognize Waymarking as a global hobby and welcome waymarks from all countries. Because of our international scope, we also acknowledge ENGLISH as our lingua franca. English will create the highest level of accessibility globally. All waymarks must have at least a short description in the long description section in ENGLISH. We encourage bilingual and multilingual waymarks, but one of the languages must be English.
Instructions for Visiting a Waymark in this Category:
1. The waymark coordinates must be personally visited.
2. Give the date and a description of your visit.
3. Post at least one photo taken at the time of your visit.
