Description

1.Product Overview
The portable navigation spoofing module is designed for counter-UAS applications in fields such as petroleum and petrochemicals, electric power, law enforcement, and the defense industry. The product features a compact and lightweight design, easy operation, and reliable performance, making it convenient for rapid user integration.
2.Main Functions
● Supports reception and simulated transmission of common signal frequencies from the world’s four major navigation satellite systems.
● Built-in GNSS band amplifier with single-frequency output power ≥ 5 dBm.
● Synchronizes with on-orbit satellite time and ephemeris, and automaticall y blocks co-frequency interference.
● Capable of spoofing UAVs dependent on satellite navigation systems, enabling forced landing, directional guidance, take-off prohibition, and GNSS interference.
● Supports external buttons and command control for functional modes including:signal ON/OFF, GNSS interference, heading guidance (expulsion), no-fly zone, circular motion, and crash mode.
● Supports an external direction-finding module to determine UAV orientation and to guide the target
● Supports external indicator lights showing the module’s operating status.

3.Technical Specifications

● Supports simulation of GPS, BDS, GLONASS, and Galileo navigation satellite signals. Details of frequency points, power, and channels are as follows:

4.Interface Definition
Product interface functions and definitions are as follows:: The interface functions and definitions of the portable navigation deception module are as follows:
Signal reception port: SMA — receives GNSS signals
Signal transmission port: SMA — transmits spoofing signals
Power and control interface: HC-PHD-2×13AW, including: power input, direction-finding module interface, external functional button interface, external indicator light interface, interface, network port.


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
NO. Function Off Flashing Solid
1 Operating status Power off Power on, initializing Initialization complete
2 Signal transmission status Signal OFF Jamming signal transmitting Spoofing signal transmitting
3 Signal reception status No satellite signal or signal reception disabled Normal satellite reception.
