Athlete tracker takes home grand prize / TTP2 / Technology / Our Activities / ESA
A small but revolutionary motion sensor worn by athletes has scored a big win in this year’s European Satellite Navigation Competition. Proposed by the ESA Business Incubation Centre start-up company Kinexon, it provides accurate, realtime information on an athlete’s condition.
The device is based on a small sensor cell developed by Kinexon that offers precise localisation and tracking. Accurate to about 10 cm and updated 20 times a second, it captures even rapid movement.
The cell combines realtime improved satnav with information from internal inertial sensors. The satnav technique increases the precision of position data from the Galileo, GPS and Glonass satellite constellations by using the ‘phase’ of the signal’s carrier wave, rather than the satnav signal information content itself.
