Drone RF Monitoring

Unmanned aerial spectrum monitoring for public and homeland security

Monitoring devices are usually positioned on high buildings or other heights or alternatively are mounted on fixed or transportable masts. For ad-hoc monitoring to protect critical sites or major events this is not always practical and feasible. The military, too, often have trouble finding ad-hoc suitable locations to place monitoring devices in areas of operations.

To extend the power supply for monitoring of several hours, an optional tethered system is used which provides permanent power supply. It is also fitted with a stable downlink communication via Ethernet cable. The tethered drone can go up to an altitude of 80m. The complete unmanned drone monitoring system can be easily transported on a pick-up and deployed quickly.

Key Applications of Drone RF Monitoring

LS telcom’s Colibrex provides drones equipped with the powerful monitoring unit LS OBSERVER.

Bringing the LS OBSERVER into the sky offers 3 main advantages:

Detection of Illegal Signals / Frequency Violation

Observes the entire RF spectrum to detect:

  • Suspicious or illegal activity
  • Potential threats
  • Unwanted emissions (jamming)
  • Radio activity from neighboring countries

Direction Finding / Homing

Use of AoA (Angle of Arrival) technology to determine the direction of the suspected emitter, using compass and a directive antenna and turning the X8 drone on its axis.

Verification of VSAT / Microwave Links
