I wanted real-time CdA to be able to tune my position. I tried Notio but was incredibly frustrated by the velocity-sensitive Notio CdA values -- Too high! Too low! No good!
I thought I could do better, so I developed cycling aero algorithms based on Kalman Filters.
At last CdA values that make sense and pass the Virtual Elevation, Virtual Velocity and Virtual Power validation tests with flying colors :) Hope you like them!
AeroStar is a web-based app for fast, intuitive and accurate CdA & Crr analysis.
I'm an avid road cyclist with a PhD in Dynamics and Modern Control Theory.
