The relative bearing is measured with a pelorus or other optical and electronic aids to navigation such as a periscope, sonar system, and radar systems.

Relative bearings then serve as the baseline data for converting relative directional data into true bearings ( N-S-E-W, relative to the Earth's true geography ).

But the measures have been largely criticized on the island, where many look forward to visits by relatives bearing gifts, cash, and stories of new lives across the Florida Straits.

In navigation, an "'electric beacon "'is a kind of beacon, a device which marks a fixed location and allows direction finding equipment to find relative bearing, the direction to the beacon.
16.
An "'automatic direction finder "'( "'ADF "') is a marine or aircraft radio-navigation instrument that automatically and continuously displays the relative bearing from the ship or aircraft to a suitable radio station.
17.
Once an ADF system was tuned to a station, either an airway beacon or an AM radio station, they continually moved a pointer to indicate the relative bearing with no further operator involvement.

"' Constant bearing, decreasing range "'( CBDR ) is a term in navigation which means that some object, usually another ship viewed from the deck or bridge of one's own ship, is getting closer but maintaining the same relative bearing.
