Marker Beacon: Part of Instrument Landing System that signals crew members of distance to runway, consisting of three markers: inner, middle, and outer.
Beacons
In 1921, the Army deployed rotating beacons in a line between Columbus and Dayton, Ohio, a distance of about 80 miles. The beacons, visible to pilots at 10-second intervals, made it possible to fly the route at night.
Beacon. An apparatus, usually on an airway, which emits light signals to indicate a particular geographical position to aircrews.

marker beacons (mkrs) - part of an instrument landing system using 75 MHz transmitters emitting fan-shaped or elliptical signal patterns vertically upwards, defining specific points along the glideslope.
marker beacons - A radio navigation aid used in the approach zone of an instrumented airport.
MARKER BEACONS On most installations marker beacons operating at a carrier frequency of 75 MHz are provided.
Airport Beacon: A navigational aid emitting alternating white and green flashes to indicate a lighted airport or white flashes only for an unlighted airport.
Radio beacons typically used in combination with an ILS instrument approach. A beacon is indicated by a light and an aural tone when the aircraft flies over the it. An ILS may have up to three marker beacons.
MARKER BEACON- An electronic navigation facility transmitting a 75 mHz vertical fan or boneshaped radiation pattern.
AIRWAY BEACON- Used to mark airway segments in remote mountain areas. The light flashes Morse Code to identify the beacon site.
ALERFA (Alert Phase) [ICAO]- A situation wherein apprehension exists as to the safety of an aircraft and its occupants.

Nondirectional Beacon (NDB) − A beacon transmitting nondirectional signals whereby the pilot of an aircraft equipped with direction finding equipment can determine his bearing to and from the station.
Behind a mountain radio reception is shielded off. Like the shadow from the mountain by the sun. LF signals also have tendency to be reflected by mountains leading you to think that a NDB beacon is in that direction.

During flight, pilots normally follow designated airways, or highways in the sky, that are marked on flight maps and are defined by their relationship to radio navigation beacons, whose signals are picked up by the aircraft.
Non-directional beacons (NDB) are another from of NAVAID used but these are more so for approaches. Really popular in the mid 1900s, they were more or less phased out for navigation by the VOR.

IM (Inner Marker) - A marker beacon used with an ILS (CAT II) precision approach located between the middle marker and the end of the ILS runway. It transmits a radiation pattern keyed at six dots per second.
One aircraft wanting to climb through the level of another when their estimated times overhead a particular navigation beacon are within a few minutes of each other, that sort of thing.
Airports that have lighting will usually also have what's called a rotating beacon that helps pilots find the airport at night.

EMPENNAGE - An aircraft's tail group, includes rudder and fin, and stabilizer and elevator. Old French: empenner, to feather an arrow, from Latin penna, feather.
I'm wondering whether there's a rotating beacon on the Nassau airport. Somehow, I doubt it. I don't think we'll see a thing until we see the runway complex.
