Core System Functions
Track-Return Home
When the drone encounters severe GNSS signal interference, the system automatically takes over flight control. Utilizing real-time stored flight trajectory and attitude records combined with compass-based inertial navigation, it ensures the drone safely exits the interference area, plans optimal flight paths, and models the boundaries of the interference area.
Auto Route Planning
Click the screen to select the monitoring area of interest on the map, set the monitoring frequency band and flight parameters, and generate a flight route to perform spectrum mapping. Capable of measuring multiple signals simultaneously. Additionally, flight intervals can be configured to create full coverage flight plans seamlessly.
Intersection Localization
During the direction-finding process, the system transmits the direction-finding results for the current frequency point in real time. By maintaining the bearing line and dynamically tracking the drone's position, it quickly extracts the location information of the intersection point on the electronic map with high precision.
Electromagnetic Situation Analysis
Based on the collected electromagnetic environment data, combined with geographic location information for precise analysis, the electromagnetic situation of specific frequency points is visualized as a heatmap. It features complete three-dimensional electromagnetic situation modeling capabilities for comprehensive awareness.
Signal Level Trajectory
Precisely captures frequency signal level variations. The system transmits real-time target frequency data and integrates it with maps, dynamically displaying it as trajectory points. Point colors intelligently adjust based on signal strength values following a visual gradient distribution layout.
Spectrum Scanning
Provides full-band high-speed scanning coverage, meeting signal detection needs across various application scenarios. Through touchscreen operation, users can easily slide the vertical axis to review signal strength levels, freely select and zoom in on specific frequency ranges precisely.
Discrete Scanning
Measures signal strength for one or multiple frequencies simultaneously based on a preset frequency list and analysis bandwidth. In environments with dense urban signal interference or forest canopy obstruction, airborne monitoring signals demonstrate excellent stability and reliability.
Single-Frequency Direction Finding
Performs rapid in-flight direction-finding executions on targeted static or fixed frequency signals. The onboard processor rapidly calculates signal arrival angles via advanced correlation interferometry methods and plots accurate bearing vectors on map screens.
Multi-View Work Mode
Switch configuration modes flexibly via absolute real-time multi-device synchronization. The architecture allows mission parameters and spectral streams to be viewed concurrently across drone controllers, mobile terminals, or centralized field base stations.
Real-Time Forensics
Leverages drone HD imaging and live video streaming to provide forensic support. With a single click for screenshots or recording, the monitoring interface integrates signal measurements to aerial-document suspect devices' appearance and precise locations.
