Regulatory landscape

Who regulates a laser link to space

Optical direct-to-Earth sits in a regulatory gap. Spectrum regimes assume a radio carrier, so most spectrum authorities have no remit over a laser link, and no optical class licence yet exists. Oversight instead lands on aviation-safety notification, laser-emission deconfliction, and dual-use export control, weighted differently in each jurisdiction. This page maps that terrain per country, from the same public filings cited on each station record. For per-station authority and dual-use status, switch the tracker table to its Regulatory lens.

The four axes

Spectrum

Radio regulators license frequency assignments. An optical carrier isn't a radio frequency, so most spectrum authorities have no remit, and no optical class licence yet exists.

Laser clearance

An uplink beacon propagated skyward must be deconflicted from aircraft and, in some countries, from other satellites, the binding control for a station that transmits.

Aviation

Civil-aviation authorities require notification or authorisation for outdoor lasers directed into navigable airspace, independent of the space mission.

Dual-use

Precision optical-comms hardware can fall under export-control lists (EU 2021/821, US EAR/ITAR, Japan FEFTA, Australia DSGL), especially where defence partners are involved.

By jurisdiction

United States

FAA airspace review + DoD Laser Clearinghouse

civil

Spectrum: No FCC licence for a receive-only optical downlink; the optical carrier is outside the radio spectrum regime.
Laser clearance: Lasers propagated to space are deconflicted through the DoD Laser Clearinghouse (predictive avoidance), the defining control for any US uplink site.
Aviation: FAA outdoor-laser notice under Advisory Circular 70-1B (Form 7140-1), returning a letter of determination.
Export: Hardware may sit on the Commerce Control List or USML depending on performance; ITAR relevance for defence-linked builds.

Applies to: Table Mountain OCTL, Palomar (DSOC downlink), Haleakalā (LCRD), NASA LCOT, UND Grand Forks, SDA / Mynaric OGS, USEI Brewster, Aerospace Corporation

European Union

No spectrum remit; aviation + EU dual-use control

civil / dual-use

Spectrum: National radio regulators (BNetzA, ANFR, BIPT, EETT, AGCOM) have no optical remit, there is no spectrum licence for the laser link.
Laser clearance: Handled at site level and through aviation notification; observatories add local laser-traffic coordination (e.g. Teide LTCS), and SLR-heritage sites (Matera, Graz) carry aircraft-detection interlocks as standard.
Aviation: National CAAs authorise outdoor-laser emissions, DFS/LBA (DE, §16a LuftVO), AESA/ENAIRE (ES), DGAC (FR), skeyes (BE), Hellenic CAA (GR), ILT (NL), ENAC (IT), Austro Control (AT), DAC (LU).
Export: Regulation (EU) 2021/821 governs dual-use exports; optical-comms terminals may fall in Annex I depending on specification. The QKD roles of EAGLE-1 Noordwijk and the INT-UQKD station at Windhof both sit inside the EuroQCI security framework.

Applies to: ESA OGS Tenerife, IZN-1, ONN Almería & Nemea, ETOGS, Holomondas, DLR Oberpfaffenhofen, TOGS & LaBoT, UniBw Neubiberg, Cailabs Rennes, FROGS, ONERA FEELINGS, MeO Grasse, ONEST Redu, TNO The Hague, EAGLE-1 Noordwijk, INT-UQKD Windhof, Matera MLRO, Graz-Lustbühel

United Kingdom

Ofcom out of scope; CAA aviation + UK strategic export controls

dual-use

Spectrum: Ofcom has no optical spectrum remit; no licence for the laser carrier.
Laser clearance: Aviation-led; deployable stations re-clear at each operating site.
Aviation: UK CAA outdoor-laser notification for beams into navigable airspace.
Export: UK Strategic Export Control Lists (retained dual-use regime); optical-comms terminals may be controlled depending on specification, and defence-linked programmes add ITAR-adjacent handling.

Applies to: RAL Space Chilbolton, Archangel Lightworks TERRA-M

Greenland (Kingdom of Denmark)

Danish/Greenland aviation; EU dual-use control

civil

Spectrum: The Danish Energy Agency has no optical remit; no spectrum licence for the laser link. Greenland's self-rule does not create a separate optical regime.
Laser clearance: Handled through Danish/Greenland civil-aviation notification for beams into airspace; no dedicated satellite deconfliction regime is published.
Aviation: Danish CAA (Trafikstyrelsen), coordinated with Greenland airspace management, authorises outdoor-laser emissions.
Export: Denmark applies Regulation (EU) 2021/821; optical-comms terminals may fall in Annex I depending on specification.

Applies to: Astrolight Greenland OGS

Australia

ACMA (below 420 THz) + CASA; Defence dual-use

civil / dual-use

Spectrum: ACMA's own market study notes its framework wasn't designed for optical satcom: infrared earth stations below 420 THz fall under the Radiocommunications Act and require authorisation, but no dedicated optical class licence exists.
Laser clearance: Aviation-led; coordinated with CASA for emissions into airspace.
Aviation: CASA laser-emission coordination.
Export: Defence Strategic Goods List; TeraNet and Mount Stromlo carry Defence Science and Technology Group ties through the Australasian Optical Ground Station Network.

Applies to: TeraNet TN-1 Perth, TN-2 Yarragadee, TN-3 (mobile), Mount Stromlo, SSC Western Australia, DSTG Adelaide

Japan

JCAB aviation; METI export control

civil

China

No public civil regime documentation

unknown / dual-use

Regime: There is no public documentation of the civil licensing regime for these optical/quantum stations. The absence of published detail is itself the finding, not evidence that none applies.

What every station shares

No ITU filing for the optical carrier. Optical direct-to-Earth links are not ITU-notified: no radio-frequency assignment is filed for the laser, so no ITU record exists for a station's optical downlink. Where a station also runs an RF telemetry or control link, that link is filed separately and is out of scope here.

The transmit / receive split decides which regimes bite. A receive-only downlink station triggers almost nothing beyond site rules; the moment a station transmits an uplink beacon, aviation notification and, in some countries, satellite deconfliction attach. The station records carry a link-direction field for exactly this reason.

Standards compatibility is not regulation, but it gates interoperability. CCSDS O3K (near-Earth) and the high-photon-efficiency profile (deep space) determine which spacecraft a station can actually close a link with, independent of any licence.

Dual-use is the live question. Precision optics, high-power beacons, and coherent receivers can fall under export-control lists (EU 2021/821, US EAR/ITAR, Japan FEFTA, Australia DSGL) regardless of who operates the site, and defence partnerships move a station from civil to dual-use quickly. This is the field most likely to surprise a commercial operator, so it is called out on every record.
