FIELD: physics.
SUBSTANCE: signaling device for identifying the aircraft accident place contains a ball (1), which is capable of filling with gas lighter than air. A radio transmitter (2) with an electronic control circuit connected to the container (3) via a flexible connection (4) is attached to the ball. The signalling device is provided with an independent power source (5). The ball (1) is made in the form of a light metallized shell, on which the resonant structures (12) are made with the possibility of reflecting the radio signal toward the radiation source.
EFFECT: improving the possibility of detecting the aircraft accident place.
