Permanent navigation aids positioned the same as a buoy are _____________________ beacons.

Permanent navigation aids that are positioned similarly to a buoy are classified as fixed beacons. Fixed beacons are established at a specific location and do not move, providing reliable reference points for mariners. These aids are typically constructed using materials that ensure durability and visibility, permanently marking hazards or safe passages in navigable waters.

In contrast to fixed beacons, floating aids like buoys are designed to move with the water currents and tides. Temporary aids may be utilized in situations such as construction work or during special events, and movable aids are intended for locations that may change frequently based on the environment or navigational needs. These options do not fit the description of permanent navigation aids, which retain a consistent location to serve as reliable markers over time.
