The Microflown acoustic vector sensor consists of three orthogonally placed particle velocity sensors and a pressure microphone. Several acoustical magnitudes are processed and calculated in order to localize moving sound sources in three dimensional spaces.  Once the noise source is detected the “Direction of Arrival”, speed, and the followed path can be easily tracked.

Combining this information with RADAR based information such as height and plane “Call sign”, every flight event can be detected, related to the exact plane, compared to its expected operational behavior and related to OACI class restriction and operational performance even if the plane doesn’t make use of a transponder system because the surveillance is carried out by acoustical measurements.

As many measuring stations as needed can be added to the control system in order to control the accomplishment of ground operations restrictions on ground or air such as APU usage or operational limitations.

The monitoring stations installed in the network are synchronized so that the recorded event can be correlated from different stations and the plane path can be followed from station to station covering several kilometer range with each system.

The system is suitable for airport operational control, plane and noise performance and airport noise public dissemination to involve the inhabitants of the area in processes such as information gathering and decision making thanks to the server based system and the definition of different information access levels.

The assessment of the noise impact to each airport operation allows to create dynamic sound maps as well as handling a proper fine system, not relying on a RADAR/ Transponder system.
