FLARM works by calculating and broadcasting its own future flight path to nearby aircraft. At the same time, it receives the future flight path from surrounding aircraft. An intelligent motion prediction algorithm calculates a collision risk for each aircraft based on an integrated risk model. When a collision is imminent, the pilots are alerted with the relative position of the intruder, enabling them to avoid a collision.
UAV must be remotely identifiable, in combination with a UAS registry database. The benefits include added security, higher safety standards, increased accountability, and easier access to airspace. The principle of electronic identification (eID) is that a cooperative UAS regularly broadcasts a unique identifier and the current position through a radio frequency digital message. This enables authorized parties to detect, identify, locate and track UAS anywhere at any time, also in the absence of network connectivity or other infrastructure.
