Remote ID explained: what drones actually broadcast

For years, a drone overhead was anonymous. You could see it, maybe hear it, but you had no way of knowing what it was or who was flying it. Remote ID was designed to change that — to bring to drones the same basic accountability a number plate brings to a car.

The idea is simple: if a drone has to announce itself, then authorities, site operators and even members of the public can identify unauthorized flights, distinguish them from legitimate ones, and respond. This article explains what Remote ID actually transmits, how the rules work in Europe and France, and where its limits lie.

What is Remote ID?

Remote ID is a requirement for a drone to broadcast identifying information while it flies. The most common form — the one used in Europe — is Direct Remote ID (sometimes called Broadcast Remote ID): the drone itself transmits a short-range radio signal, typically over Wi-Fi or Bluetooth, that any nearby receiver can pick up. There is no internet involved and no central server in the loop; the information travels directly from the drone to whoever is listening on the ground.

There is also a second model, Network Remote ID, where the drone's data is sent over the internet to a central service. In Europe this is associated with U-space, the framework for managing drone traffic in designated airspace, and is not yet universally required. For the purposes of detecting a drone over your site, it is Direct Remote ID — the local broadcast — that matters.

What information does Remote ID broadcast?

A Direct Remote ID broadcast is richer than most people expect. Depending on the drone and standard, it can include:

• A unique identifier — the drone's serial number or a session ID, the equivalent of a licence plate.
• The drone's live position — its real-time GPS coordinates.
• Altitude — how high it is flying.
• Speed and heading — how fast it is moving and in which direction.
• The remote pilot's position — or, if that is unavailable, the take-off point.

That last item is the one that changes everything for security teams. A signal that reveals not just the aircraft but the operator's location turns a detection system into a response tool. A receiver on the ground can display the drone and the pilot on the same map, in real time — which is exactly what makes locating the operator possible.

The rules: Europe and France

In the European Union, Remote ID is governed by Regulation (EU) 2019/945 (technical requirements) and Regulation (EU) 2019/947 (operations). Since 1 January 2024, Direct Remote ID has been mandatory for:

• All drones flying in the specific category, and
• Drones with class marks C1 to C3 (broadly, most camera drones above 250g) flying in the open category.

The main exemptions are very light C0 drones under 250g, certain C4 model aircraft, and some tethered systems. In practice this means the great majority of the camera drones used commercially and by serious hobbyists are required to broadcast.

France adds a national layer. Since 2019, French rules from the DGAC have required an electronic "remote reporting" beacon for drones above 800g, predating the EU rule. The result is that, in France, heavier drones may carry both the French electronic-reporting signal and the European Direct Remote ID — a double identification regime that, for a detection system, simply means more identifying signal in the air.

Remote ID vs manufacturer protocols

Remote ID is a regulatory standard, but it is not the only thing a drone transmits. Every drone also maintains a control link with its operator — the radio connection that carries commands up and video down. Major manufacturers such as DJI and Autel use their own proprietary protocols for this link.

This distinction matters for detection:

• Reading Remote ID identifies compliant drones that are broadcasting their regulatory identity — the cooperative majority.
• Listening to the control link and matching it against a signature library identifies drones by make and model even when they are not broadcasting Remote ID — the non-cooperative ones.

A capable detection system does both: it reads the standardized Remote ID broadcast and it recognizes manufacturer signals. That combination is what lets it cover both the drone announcing itself by the rules and the one trying not to.

The honest limit of Remote ID

Remote ID is powerful, but it is not magic, and it would be misleading to present it as a complete solution. It only works when a drone is compliant and actually broadcasting. A determined bad actor can fly an exempt sub-250g drone, disable a beacon, or use a non-compliant aircraft — and that flight will not announce itself.

Remote ID catches the cooperative majority. Real security planning also has to account for the uncooperative minority.

This is why Remote ID reception is best understood as one layer — a very valuable one — within a broader detection approach. Combining Remote ID with passive RF detection of the control link closes much of the gap, picking up drones that stay silent on the regulatory channel. For high-security sites, detection is treated as layered by design, and contacts are validated in the field rather than trusted blindly.

What this means for protecting a site

For a security team, the rise of Remote ID is good news. A standard that requires most drones to broadcast their identity and their pilot's position has made affordable, passive airspace awareness realistic for organizations that could never have justified heavy radar installations. You no longer need to be a national agency to know what is flying over your perimeter.

SkyKraken is built to make the most of this. It reads Remote ID broadcasts and recognizes the proprietary signals of major manufacturers like DJI and Autel, identifying make, model and unique ID, and — for compatible drones — locating the pilot and take-off point. It presents everything on a live, offline tactical map, and can turn any detection into a timestamped evidence dossier. The standard provides the signal; SkyKraken turns it into a picture you can act on, and proof you can keep.
