1. Small, Lightweight Speed and Distance Sensor
for Skiers and Snowboarders
ECE 480 Design Team Six
Abstract:
Measuring one’s performance can be difficult for skiing and snowboarding, mainly due to lack of repetitive movements, such as those found in other activities like running and cycling.
To overcome this challenge, Design Team Six proposes a lightweight speed and distance sensor based on the integration of a Global Positioning System (GPS) and an Inertial Navigation System (INS) through Kalman filtering.
Technical Approach
A Global Positioning System (GPS) integrated with an Inertial Navigation System (INS) through a Kalman filter
Problem:
Create an affordable lightweight speed and distance sensor for skiing

Measure speed, distance, top speed, and record data for future review
A Kalman filter is an advanced integration technique used to dynamically correct error in a noisy system
Objective:
Intended to track speed,
distance, and top speed
Operable by any individual
Easy to use, no training required
This solution provides unmatched accuracy compared to the competition
