HAIN Reference
Acoustic and Inertial positioning principles in combination is ideal since they have complementary qualities. Acoustic positioning is characterised by relatively high and evenly distributed noise and no drift in the position, whilst Inertial positioning has very low short-term noise and relatively large drift in the position over time.
