Re: Flight Predictions

Joe, the HABhub tracker does this - it takes the transmitted data (position and altitude) from the balloon and corrects the predicted trajectory based on where the balloon currently is, how fast its ascending/descending etc.
I addition the Raspberry Pi Pi-In-the-sky (PITS) software can (if configured) do onboard calculations based on ascent and descent rates to calculate a landing spot. That predicted landing spot is transmitted along with other data. The Pi calculated landing spot can be overlaid on the HABhub tracker (in addition to the trackers own prediction of landing spot) and can also be taken directly by the chase vehicles.
Here are a couple of videos of the HABhub tracker predicting the landing spot during real flights:
keep you eye on the blue line and dot (HABhub prediction) and the
red X that of PITS
