[0034] The wireless connectivity allows the Spectrum Analyzer 3 to be deployed more flexibly, without being limited by geographical location. At the same time, the real-time data transmission and analysis capabilities enable the ground control unit to respond quickly and take necessary measures to eliminate interference.

These interfaces also provide the drone platform with powerful scalability, allowing users to connect various external devices as needed.

[0050] Working principle: During use, during flight preparation, the ground control terminal 4 operates the interference location software to set the target frequency band and collect data. The UAV platform 1, equipped with the frequency sweeping module 2, flies to at least one target fixed point. The frequency sweeping module 2 works, and the UAV platform 1 rotates 360 degrees at the target fixed point to perform measurement work, measuring the test data of the interference signal at the target fixed point, outputting the results, and sending the test data to the ground control terminal 4 for precise positioning. The UAV performs a three-point spin test, and with the cooperation of the detection software at the ground control terminal 4, the location of the interference source is quickly and effectively determined using the three-line positioning method to resolve the interference, assess whether the interference source is causing uplink interference, and output reasonable solutions for the target interference source.
