5.Function Definitions
The portable navigation spoofing module uses external buttons or command control to switch working states and functional modes.
| Function Button Definitions | ||
|---|---|---|
| NO. | Function | Function Description |
| 1 | Signal transmission & mode switch | When the transmit button is pressed, and without pressing the function-mode button, the device transmits a GNSS suppression jamming signal. When the function-mode button is pressed, it transmits a GNSS spoofing signal corresponding to the selected mode. GNSS Signal Suppression Jamming Function: Based on GNSS signal-simulation technology, the system provides an intelligent jamming capability that enables low-power, long-range suppression of satellite-navigation signals. |
| 2 | Crash mode | Forces the target UAV to crash toward the ground in a specified direction. |
| 3 | Heading guidance (forward) | The module connects to an external direction-finding unit to determine its own orientation. Guides the target drone to fly forward away from the user. |
| 4 | Heading guidance (backward) | Guides the target drone to fly backward away from the user. |
| 5 | Heading guidance (left) | Guides the target drone to fly left away from the user. |
| 6 | Heading guidance (right) | Guides the target drone to fly right away from the user. |
| 7 | Circular motion | Induces the UAV to perform circular flight in the air. |
| 8 | No-fly zone | Spoofs the UAV position into a no-fly zone, causing forced landing or preventing take-off. |
6.Indicator Light Functions
Portable navigation deception module, with external indicator lights defined as follows:
| Definition of Indicator Light | ||||

The anti drone module brings its connections out to standard hardware. One SMA port receives the GNSS signal from the antenna, and a second SMA port transmits the spoofing signal. Power and control run through an HC-PHD-2×13AW connector that also carries the direction-finding module interface, the external function button and indicator light lines, and a network port.
Four indicator outputs tell the operator what is happening without opening the housing: operating status (power off, initializing, initialization complete), transmission status (signal off, jamming signal transmitting, spoofing signal transmitting), reception status (no signal, tracking, or locked with sufficient ephemeris) and an alarm that flashes if the receiving antenna or the direction-finding module is missing. Inside, the electronics sit in a flat metal enclosure with a screw-fastened lid and corner mounting holes, so the unit can be fixed to a bracket or inside a control box rather than needing a rack of its own.

It handles all four major navigation satellite systems: BDS-B1, GPS-L1, GLONASS-L1 and Galileo-E1. A built-in GNSS band amplifier sits in the transmit chain, so both the reception side and the simulated output are managed inside the one enclosure.
The maximum effective distance is about 2 km, and in practice it depends on the electromagnetic environment, the transmitting antenna used and the drone model being targeted. Power output can be adjusted across a wide range, so operators can tighten or extend that footprint to suit a confined site or an open perimeter.
Pressing the transmit button alone turns the module into a portable signal jammer: it suppresses satellite navigation reception over a low-power, long-range footprint. Pressing it together with a function-mode button instead transmits a spoofing signal matched to that mode, so the drone's receiver is fed a false but internally consistent position.
After power-up the module starts in about 30 seconds, and roughly 150 seconds should be allowed for it to synchronize with on-orbit satellite time and ephemeris before transmission begins. The external indicator lights confirm when reception is locked and the module is ready.
Continuous operating time is at least 24 hours. Standby draw is 5 W or less and rises to no more than 9 W while transmitting at maximum power, so the unit can sit ready without a heavy load on the site's supply.
Operating temperature spans −30 °C to +70 °C, and the module can be stored from −40 °C to +80 °C, both compliant with the GJB1621.7A-2006 standard. That suits outdoor cabinets and unheated shelters in most climates, and the unit can be carried between positions when needed.
