1. FSAE Telemetry Alex Pfarr, Emily Peterman, Lonny Cooper & Clint Young seniordesign.engr.uidaho.edu/2005_2006/witel/index.html

2. Telemetry Needs Create user-friendly interface for monitoring vehicle systems from trackside during testing. Support analysis of vehicle position, velocity, forward acceleration, and lateral acceleration in real-time (5- 10hz) and post-race (up to 100hz). Monitor wheel speed, brake pressure, steering angle, and throttle position in real-time and post-race. Send images from one on-board camera location to track side during testing. Monitor fuel injection and ignition timing in real-time via MOTEC engine control computer (requires separate trackside computer)
