BlackFIR® is a technology based on a combination of angle-of-arrival measurement, i.e. the determination of the angles at which signals reach an antenna array, and time-of-flight techniques, which measure how far away a given tag is.
Based on the angle and distance determined, it is then possible to calculate the position of an object equipped with transmitters. Fusing the result with sensor data (from accelerometers, barometers, gyroscopes) helps refine the calculated position or determine its reliability.
BlackFIR® works in various frequency bands and can be adapted to a wide range of radio transmission standards, which means it is suitable for both indoor and outdoor use. Its robust infrastructure enables several hundred measurements per second and makes it possible to calculate the positions of moving objects with an accuracy of 0.5–1 m.
