Airborne wireless signal monitoring to ensure the flight safety of low-altitude economical drones

1、Scan, detect and inspect radio signals in the air;

2、Monitor and recordInterference signals in the GNSS frequency band, and direction finding and positioning of interference signals;

3、Determine the flight space of the drone4G/5G/5G-A signal coverage;

4、Detecting and monitoring illegal drone incursions;

5、Conduct real-time environmental inspections and monitoring of drone routes.

Case1

The following figure shows theAn example of a signal related to UAVs:

The frequency hopping narrowband uplink signal and the stable wideband downlink signal are clearly visible in the display, along with some signals from the remote device.WiFi signal. The diagram proves that this block DPX display may be the most effective way to detect drone intrusion through RF signal monitoring.

Case2

pictureFigure 21 shows a playback of spectrum data captured by the WSA-208 while in flight. The spectrum clearly shows evidence of interference from a wideband swept-frequency signal source in the 1.575 GHz GNSS band.

This interference is likely coming from some anti-drone jamming equipment.

Case3

A unit received an investigation and identificationAfter the 1090MHz air traffic control signal interference mission, the WSA208 spectrum analyzer function was used for testing and verification, and direct evidence of interference from the second harmonic of the TV station signal was finally found and confirmed.
