Drone tracking is accomplished using Time Difference of Arrival (TDOA) to continuously geo-locate drone positions. To perform tracking, a minimum of three remote spectrum monitors are required to monitor and track the drone video signal. Typically the RSMs are setup in a triangle formation to maximize the precision of each TDOA measurement.

IQ measurements are used for TDOA analysis. Given the bandwidth requirements for IQ data, it is important that the backhaul from each RSM be high-speed. It is recommended that either Ethernet, optical fiber, or point-to-point microwave be used.

Once the signal is detected and validated, tracking will automatically begin. Users may view drone positions on a map overlay. Additionally, alarm information can be sent to a user provided system software console (using the API guidelines) where other sensors may be used to supplement the RF detection and tracking process. These sensors may include radar, optical (camera) tracking, acoustic or other alternatives.
