Research by Ryan Beall and Chaz Henderson:

I did a little more refining of the model from the data previously described/collected from the Pixhawk.  The following are the results of System Identification and PID optimization.

The overall performance of the bank angle controller was…

I have been working on an improved altitude estimator for a while here but have been having issues with implementation.

 

The theory works fine but as seen above in the FFT of the accelerometer data,…

Improved Altitude Estimate

Posted on December 5, 2010 at 7:30pm 26 Comments

The barometric sensor alone in most cases provides noisy and drift prone measurements. I have been trying to come up with a simple way to implement a fixed gain filter to utilize the acceleration measurements from the accelerometers to help clean up the noise and also add a sanity check via sensor fusion.…

I use different company's for batch depends on what i want. If i need a few board but fast i use advanced circuits (super expensive). A few boards and cheap i use Batchpcb.com and mass production i use any China company like custompcb.com. Sparkfun uses goldphoenixpcb.biz/
