"I am a graduate aerospace student at CU, and I feel the need to add some clarification. As a public research institution, we are subject to different rules than the hobbyist community. So there is a lot of restrictions on what the team can actually…"
I think I read your post incorrectly, I need to remember to not use the internet when I wake up! You are right that the DCM is used for control, but it might be interesting to use quaternions in the control loop. Always impressed with your…"
"Actually you don't need the DCM for the body transformation, you can use the elements of the quaternion vector for the entire transformation matrix. And since its all linear operations, it is faster. The singularity in the DCM comes when the pitch…"
I have followed the progress of your hardware for a couple of years now, I have a suggestion for you though. Instead of the DCM approach, you may want to consider quaternions. They are much faster computationally, although not as intuitive.…"
"The University of Colorado at Boulder is already doing this, and have been doing optimized radio node research for nearly a decade now. I suggest checking recuv.colorado.edu or augnet.colorado.edu to review the work done. We are doing things with…"
"Yes, I saw the battery backup, but I was a bit unclear on how it worked.
I think I am going to try to use Sparkfun's RS232 shifter, or breadboard it. RS232 would be a bit more convenient for me than FTDI, but I have enough budget to try both.…"
