The École polytechnique fédérale de Lausanne research institute/university in Lausanne, Switzerland just published this video about some technology they have been cooking up to better track the movements of ski racers on course. The system measures a skier’s exact time at each gate and also calculates the skiers’ speed and trajectory more accurately than GPS.
Benedikt Fasel spoke with phys.org about his teams developments:
“We found that by combining systems designed for different purposes, we could determine a skier’s time, speed and trajectory both accurately and automatically. An ordinary or low-end GPS, like the type used in mobile phones, can measure speed and position with a lower level of error. But these systems are not accurate enough. We’d like a resolution of 10 to 15 centimeters.”
If you’re a racer, you understand that the smallest improvements can translate big gains at the end of your run and using cutting edge technology like the one developed by EPFL can give you invaluable insight into your form and performance.
