4-band GNSS spoofing navigation module for handheld portable anti drone counter-UAS

This is the  portable four-band GNSS navigation spoofing mini board developed by Shiningintl ., intended for anti-UAV and counter-drone applications in sectors such as energy infrastructure, public security, and military use. The compact and lightweight board uses navigation satellite signal simulation technology to generate spoofed GNSS signals that mimic real satellites, causing UAVs to calculate false positions. This enables multiple decoy and control effects, including course guidance, expulsion, forced landing, take-off prohibition, signal interference, and crash landing.

The module supports GPS, BeiDou (BDS), GLONASS, and Galileo signals in the L1/E1/B1 bands, with multi-channel transmission capability and adjustable output power up to ≥10 dBm. It allows flexible control through external commands, enabling users to define coordinates, motion parameters, trajectories, and signal combinations. Integration with an external direction-finding (DF) module allows directional UAV guidance.

The board supports real-time and permanent ephemeris modes, serial and network control interfaces, and optional jamming output. It operates on DC 10–28 V, consumes ≤9 W, and is designed for reliable operation across wide temperature ranges, making it suitable for embedded deployment in counter-UAV systems.

Product Description

Product Introduction

The mini navigation spoofing board produced by Shiningintl is suitable for anti-UAV scenarios in the fields of petroleum, petrochemical, electric power, police, and military industry. The board is compact, light, easy to use, and reliable in function and performance, which is convenient for users to integrate quickly. Based on the navigation satellite signal simulation technology, the board broadcasts the simulated satellite signal consistent with the navigation satellite signal by simulating the in-orbit navigation satellite signal. After the UAV receives the analog satellite signal sent by the equipment, it uses the analog satellite signal to locate and output the corresponding position. Various decoy modes for the unmanned aerial vehicle can be realized, including course guidance, expulsion, forced landing, rapid crash, and the like;
