Airspace security knowledge hub
Practical guides to help security, operations and management teams understand drone threats and deploy the right detection technology — for the French, European and US markets.
Curated by the DECTYR engineering and operations teams, the Knowledge Hub gathers our reference documents on drone fundamentals, Remote ID standards, RF and radar detection, regulations and operational playbooks. Each guide is written for buyers, security managers and integrators who need to make informed decisions, not vendors.
Topics covered
Drone fundamentals: what is a drone?
What a drone really is, how it communicates with its pilot, and the categories you will encounter in the field — from sub-250 g consumer quadcopters to fixed-wing professional aircraft.
Learn more →02Drone applications: how are drones used today?
A practical tour of legitimate and illegitimate drone uses — inspection, mapping, agriculture, photography, smuggling, espionage — and what each one means for your security plan.
Learn more →03Drone laws: regulations in France, the EU and the USA
An operator-friendly overview of EASA categories, French Alphatango rules, FAA Part 107 and Remote ID — to understand who can legally fly, where, and how you can enforce it.
Learn more →04EASA Opinion No 06/2026: the 100 g threshold and Direct Remote ID
What the 18 September 2026 opinion proposes on registration, identity verification and Direct Remote ID — and what is not yet applicable law.
Learn more →05UAS geographical zones and national conditions
How a sensitive site is protected in the European framework, and what EASA Opinion No 06/2026 changes about publishing zones and justifying them.
Learn more →06Drones already sold: who will actually broadcast Direct Remote ID?
The 100 g threshold will not make the fleet already in circulation cooperative overnight. Here are the retrofit exemptions proposed in EASA Opinion No 06/2026.
Learn more →07Drone detection and personal data
What a Remote ID frame and a detection log hold in personal data, and how to frame the processing without turning security into an identity file.
Learn more →08Telling a drone from an aircraft: Remote ID and ADS-B
Why a helicopter or a light aircraft raises doubt on a site, and how ADS-B complements Remote ID without replacing it.
Learn more →09Drone risk assessment for sensitive sites
A structured framework to score drone threats against your assets — likelihood, intent, capability, consequence — and choose a proportionate response.
Learn more →10Building a drone (UAS) policy for your organisation
What to put in your internal UAS policy: authorised use, no-fly rules, incident response, evidence handling and how to coordinate with police and aviation authorities.
Learn more →11Who makes drone detection hardware?
An honest tour of the drone detection vendor landscape — RF, radar, acoustic, electro-optical — with the technical and political questions you should ask before buying.
Learn more →12Drone detection technology: how to see drones in your airspace
The four main detection technologies (RF, radar, EO/IR, acoustic) compared on range, false-alarm rate, weather sensitivity, regulatory footprint and total cost of ownership.
Learn more →13Counter-drone (C-UAS) technology: stopping a drone with technology
Detection alone is not interdiction. We explain jamming, spoofing, capture nets, kinetic effectors — and the strict French and EU legal limits on using them.
Learn more →14Buyer's guide to counter-drone technology
How to write a counter-UAS requirement, structure your tender, run a proof-of-concept and avoid the most common procurement mistakes in France and Europe.
Learn more →15Drone detection tender: public procurement, private RFP and technical specification
Public or private drone-detection procurement in France: 2026 procedures, “or equivalent”, and a Word specification for an RX-5 and Hub fleet.
Learn more →16Drone detection software: turning sensors into decisions
Why a hypervision layer matters: sensor fusion, alerting, evidence-grade reporting, multi-site supervision and integration with VMS, SIEM and PSIM platforms.
Learn more →17Remote ID fundamentals: the drone licence plate
What Remote ID broadcasts (and what it doesn't), the differences between ASTM F3411, EN 4709-002 and the French signalement électronique, and what they mean for cooperative detection.
Learn more →18Legally preventing drones over your property
Your rights, the airspace classification myth and the realistic options for residents, site managers and operators who want to keep intrusive drones away.
Learn more →19A security professional's guide to countering the drone threat
A blueprint for security teams: from detect-track-identify-mitigate-document (D-TIM-D) to building an evidence chain that holds up with prosecutors and insurers.
Learn more →20Choose the right drone detection solution for your facility
The site-survey questions, environmental factors and scalability checks that should drive your technology choice — beyond a datasheet comparison.
Learn more →21Understanding RF drone detection
How passive RF detection actually works, why range varies in real-world conditions, and what to expect from cooperative (Remote ID) versus non-cooperative RF detection.
Learn more →22Understanding radar drone detection
How modern micro-Doppler radars detect small drones, what limits them (clutter, bird discrimination, regulatory licensing) and where they complement RF detection.
