ANIMAL TAG, METHOD AND COMPUTER PROGRAM FOR DETERMINING BEHAVIOR-RELATED DATA

摘要

An animal tag (100) contains first and second three-dimensional accelerometers (1101; HO2) and a processing unit (120). The first accelerometer (1101) registers a first acceleration vector ([a 1 ]) describing a spatial movement of a first position (p1) of the animal tag (100). The second accelerometer (1102) registers a second acceleration vector ([a2]) describing a spatial movement of a second position (p2) of the animal tag (100), which second position (p2) is separated from the first position (p1) by a distance (dxyz). The processing unit (120) receives the first and second acceleration vectors ([a 1 ]; [a2]); and based thereon, determines at least one behavior-related parameter for an animal (A) carrying the animal tag (100) in the form of inclination angle(s) (ψ, Φ, θ) of the animal tag (100) relative to a reference frame (XYZ) external to the animal tag (100), and/or an elevation (z) of the animal tag (100) relative to a reference level (XY) external to the animal tag (100).
