How It Works

Working as part of a wider set of anti drone equipment, the module receives live aerial navigation signals and extracts the timing and data it needs.
Where live reception is not possible, ephemeris data can be downloaded and injected so a simulation set is ready to run.
The module generates and transmits simulated navigation signals through its output ports at the power level you set.
A drone that follows those signals can be forced to land, expelled from the area, guided in a chosen direction, or held outside a defined no-fly zone.
Flight paths can be set to constant-speed, acceleration or circular profiles when a controlled pattern is needed.

Hardware & Mounting

Physically, this is a flat, sealed metal enclosure with a screwed-down lid and a brushed silver finish. The spoofing outputs and the GNSS receive input sit together along the front face on SMA connectors, next to the network control port, so cabling stays on one side when the unit is fitted into a rack or cabinet. Mounting flanges carry bolt holes, which lets you fix the module to a panel or chassis instead of leaving it loose.

That layout suits anti drone equipment that has to live inside an enclosure: nothing has to be reached from the rear, and the metal body shields the board assembly underneath. Drone defense companies typically mount the unit near the antenna feed and run the control link back to the operator position. If the module is going into an outdoor cabinet, confirm the enclosure protection you need with us before ordering.

Deployment Scenarios

Oil, gas and petrochemical sites — keep intruders away from process areas and tank farms, where a loose drone or an uncontrolled crash is equally unwelcome.
Electric power infrastructure — substations and transmission corridors, where the aim is usually to move a drone off the asset or bring it down in a clear area.
Public security and sensitive events — push a drone out of restricted airspace without a hard takedown.
Integrated deployments — inside a larger anti drone system, the module takes its cue from radar or RF detection and handles the final stage.
System builders — drone defense companies build the unit into their own racks, enclosures and command software. Anti drone companies that watch airspace on behalf of clients use it as the action layer once a detection is confirmed.
Research and calibration — engineering teams that need repeatable navigation signals for receiver testing and timing checks.

FAQ

Q1. What is the difference between this spoofing module and a jammer?

A jammer blocks radio links, so a drone loses contact with its controller. This module works differently: it generates simulated navigation signals that a receiver reads as a satellite fix, which lets you guide or reposition the aircraft instead of simply cutting it off. Many sites use both approaches at different stages of the same response.

Q2. Can we control the module from our own software?

Yes. The module is built with standard interfaces and protocols for secondary development, which means your engineers can drive it from existing control software or write their own routines around it. If you need a specific command set, tell us what you are working with and we will confirm what the module supports.

Q3. Where does this module fit in an existing anti drone solution?

It takes the action stage. Radar, RF detection or a spectrum sensor identifies a drone that should not be there, and the module generates the navigation signals that move it — steering it away from the protected area, holding it out of a zone, or bringing it down where the site chooses. Because the handover between detection and action is what makes or breaks a deployment, it is worth agreeing your trigger logic with us before installation.

Q4. Does the module need an operator watching it all the time?

No. It is designed for all-weather, long-range autonomous operation: once it is powered and configured, the module can sit inside an anti drone defense system and receive, generate and transmit without an operator driving each step. Teams usually monitor it and step in only to change the power level or the area they want to protect.

Q5. How quickly is the module ready after power-up?

From a cold start it is ready to transmit in 60 seconds or less. That is fast enough for pop-up protection and for joining an alert that is already in progress. If the module is part of an automated response chain, factor that start-up window into your handover rules.

Q6. Can it bring a drone down in a controlled place?

Yes — working with auxiliary radar devices, the module can guide a target to a precision landing instead of just pushing it off course. Sites that would rather recover an aircraft in a known spot, or avoid debris coming down in a busy area, tend to use this mode.
