Turning Point:Trajectory Analysis for Skiers

As with a growing number of athletes, competitive skiers are looking to GNSS technology to help evaluate and improve performance. Positions logged during practice runs or races can be transformed into 3-D models of the exact trajectories skied to measure velocity, accelerations, and other performance variables. However, terrain and trees and other obstructions along a ski run can block satellite signals - suggesting  a need to add low-cost inertial sensors to support continuous, accurate, and affordable positioning.
