Almost all freely available drones use radio signals. On the one hand, they receive commands from the remote control, on the other hand they send data such as video images or telemetry, e.g. position or remaining battery power, to the remote control.
The market-leading radio frequency (RF) DedroneSensors receive and analyze these signals and are able not only to reliably detect drones, but also to classify them - i.e. identify the manufacturer and/or model - and locate them. This applies to almost all commercial, hobby and home-made drones and the entire DJI product line.
The DedroneSensor RF-160 forms the basis of the sensor network and is also ideal for an initial risk analysis. In combination with several DedroneSensor RF-360s, drones are not only detected, but also located and tracked.
