ABSTRACT:
A method and device for calculating ski-jump lengths and the speed of travel of a skier along a ski-jump course comprises a shock sensitive radio transmitter attached to the skier's ski, a stationary radio receiver, a plurality of optical sensors, means for determining a skiers speed and an electronic unit for calculating ski-jump length. Upon impact, a signal transmitted by the radio transmitter is received by the radio receiver together with signals from the optical sensors which detect passage of the skier on the ski-jump course; said signals are then entered into the electronic unit and the means for determining the skier's speed. The electronic unit and the means for calculating the skier's speed respectively calculate the ski jump length and the skier's speed.
