1. A method for determining vertical drop of a moving sportsman, comprising:
- processing data from a GPS receiver at predetermined intervals to determine height; and
comparing height at a first time with height at a second time, to determine vertical drop of the sportsman between the first time and the second time.

Abstract
A system for determining airtime, speed and/or drop distance of a moving sportsman includes at least one accelerometer for detecting vibration or acceleration of the sportsman and/or a GPS unit. A processor in communication with the at least one accelerometer may process signals from the accelerometer to determine free-fall.
