"If it works as seamlessly and as intended, then $1000 sounds like a deal to me, given the current state of the art."

Georacer commented on Jose.L.Jr's blog post Basic Air Data 8mm Pitot Tested in Wind Tunnel
"Not my expertise, but I think the outside surface would be much more significant. Since there is no airflow inside the Pitot probe, just pressure buildup, the inside finish shouldn't matter. The outside would, on the other hand, at least up and…"

Georacer commented on Ryan Beall's blog post SISO Model and PID comparison
"I think the hardest PID gain to match with Simulink is D. Simulink will accompany D with N (The low-pass filter time constant) which also depends on sampling time. Did you find any difficulties there?"

Posted on November 8, 2013 at 3:00pm 21 Comments

Figure: Did I really fly through the ground?

I hoped I wouldn't have to do another Black Box Stories episode, but unfortunately I need help. The good thing is that no planes where harmed during this event.

Here is the backstory:

Altitude Comparison: barometer vs GPS

Posted on May 23, 2013 at 3:30pm 34 Comments

This might be a common knowledge, but in the last months I haven't seen a similar post. Maybe someone new to barometers might be interested in this data.

The GPS receivers return altitude data, but this is inaccurate. The error margin depends on the satellite constellation geometry…
