Spoofing Modes & Response Levels

Directional diversion — push an approaching drone off its line of travel so it never reaches the asset it was aimed at.
Heading guidance — feed a course correction that walks the aircraft along a route you choose, away from a boundary.
Circular motion control — hold an intruder in a steady pattern over open ground while the operator decides on the outcome.
Forced landing — command a controlled descent inside a defined stop area rather than letting the drone fly on.
No-fly zone enforcement — make the protected perimeter a position the drone's navigation will not accept, so it turns away before it arrives.
Precision landing with supporting detection — where an auxiliary detection system supplies the track, the unit can bring the aircraft down at a specific point.
Three-level response — prevention (no-fly lock), control (course guidance or area expulsion) and termination (forced landing) all run from the same unit.

GNSS Signal Simulation & Timing

Spoofing only works if the false signal is convincing, so the unit is built around GNSS signal simulation rather than a plain transmitter. It produces navigation signals that match real in-orbit satellites in structure and timing, which is why a drone treats them as genuine. In counter UAS work that authenticity is the whole point: the aircraft keeps flying normally while its idea of where it is changes. A built-in receiver synchronises the output to real satellite time, per-channel delay can be adjusted to suit the spoofing distance, and co-frequency interference is suppressed automatically.

Satellite ephemeris data can be downloaded, injected, stored, updated and recalculated on board, so the unit keeps producing valid signals where live reception is weak or blocked by terrain. Self-diagnostics run continuously and report faults before they leave a gap in coverage, and standard interfaces and communication protocols are provided for integration and secondary development.

Range & Output Options

5 km / 5 W — for a single facility or compact compound where the airspace to control is a few kilometres across.
10 km / 20 W — a middle option for larger industrial sites and compounds that need a wider buffer around the boundary.
20 km / 50 W — for long perimeters and approach corridors where the response should begin well before an intruder arrives.
Customised builds — spoofing range, band set and functional configuration can all be adapted, with output power matched to the distance you need to cover.
Matching the configuration to the site — start from the radius you must keep clear and the directions the risk comes from, so the anti drone solution covers ground you actually protect rather than a nominal circle.
What to confirm before ordering — the radius to be cleared, the constellations you need enabled, the console the unit will be driven from, and whether detection from other counter drone companies already covers the site.

Site Installation & Commissioning

Survey the perimeter. Walk the site with your security team or the anti drone companies handling the installation, and mark where a fixed mount has an open sky sector, because the unit needs that view for satellite reception.
Mount the anti drone device. Its ribbed, finned housing is built for fixed installation on the side brackets; leave clearance around the cooling fins so heat can escape.
Position the antennas. The transmitting antennas and the GNSS receiver antenna are separate runs, so keep them apart as shown in the layout drawing and keep the transmit path clear of large reflective structures.
Connect power and control. Wire the mains supply and run the data and command link back to the console or laptop that will operate the unit.
Let it synchronise. On first power-up the unit acquires satellite timing before spoofing begins, so allow for that initial lock during commissioning.
Verify with self-diagnostics. Run the built-in checks, confirm fault reporting, and record the settings for your operating procedure.
Confirm authorisation. Satellite navigation spoofing is regulated in most countries, so make sure permits and operating rules are in place before the unit transmits.

FAQ

Q1. What is the difference between spoofing and jamming?

Jamming floods the frequency a drone uses and breaks the link, after which the aircraft does whatever its failsafe dictates — hover, return to start or carry on under autopilot. Spoofing replaces the satellite signals the drone navigates by, so it keeps flying normally while its position and heading are quietly corrected. That predictability is why counter UAS deployments choose spoofing when the outcome has to be controlled rather than simply interrupted.

Q2. Which drones can this system affect?

Any UAV that relies on satellite navigation to fly a route or hold a position. The unit simulates the civil signals of the major navigation constellations, which covers the receivers used by consumer and commercial multirotors and by many fixed-wing platforms. Aircraft flown entirely by hand, or navigating on optical and inertial systems alone, are outside what an anti drone system of this type can steer.

Q3. Does darkness or bad weather limit how well it works?

No. It is built for all-direction, all-weather duty, and because it works on the navigation signals a drone receives rather than needing a line of sight to the aircraft, darkness, haze and a low cloud base do not hold it back. Rain, dust and wide temperature swings are handled by a metal housing made for permanent outdoor installation.

Q4. Can it be integrated with detection equipment we already run?

Yes, and that is how most sites run it. Standard interfaces and communication protocols let the unit be commanded from an existing console, and radar-compatible directional spoofing means a track from your radar or RF sensor can be handed over directly. System integrators and counter drone companies use it as the response element behind their own detection, and we provide the protocol documentation needed to drive it.

Q5. Can the range or the satellite bands be customised for our site?

Yes. The spoofing range can be configured beyond the standard distances, with output power matched to the coverage you need, and GNSS frequency bands and functional settings can be adapted to the deployment. Most projects start from the radius you have to protect and the constellations your risk profile calls for; describe the site and we will help size the anti drone solution around it.

Q6. Will it interfere with our own GNSS receivers and timing equipment?

The unit suppresses co-frequency interference automatically, and its output can be attenuated to the level the site needs rather than run flat out, so disruption to nearby equipment stays within what the task requires. It is still a transmitting anti drone device, so keep your own reference and timing antennas in a separate zone and mark their positions during the site survey. Tell us which GNSS equipment the site already depends on and we will help plan the antenna placement around it.
