## Editorial
The FANTANA Laser Ranger is a combined ranging and beam-stabilisation module developed by Fantana GmbH (Vienna, Austria) for use in free-space optical laser communication terminals.[^fantana-laser-ranger-page] It performs two functions: active ranging to track the distance to a remote optical terminal so the laser beam can be dynamically focused, and beam-stabilisation using a four-quadrant detector that measures real-time beam deviation and feeds a tip-tilt mirror for pointing correction.[^fantana-laser-ranger-page] It is designed as a sub-system within satellite-to-ground or satellite-to-satellite FSO communication terminals where atmospheric turbulence and platform motion cause beam wander, and operates in conjunction with Fantana's cooled single-photon receiver.[^fantana-cspr-ref] Operating wavelength, range accuracy, and spaceflight deployment heritage were not publicly documented at the time of research.
