Gyroscopes are widely used to measure the orientations and rotation speeds of moving objects – but according to one pair of researchers, the techniques we currently use to measure them are introducing significant and easily avoidable errors. Through their research, Dr Sara Stančin and Dr Sašo Tomažič, both at the University of Ljubljana in Slovenia, introduce a mathematical framework which accounts for how all three rotations measured by a gyroscope happen simultaneously, rather than in a sequence.
