JC replied to Chris Anderson's discussion Discussion forum for UAVDevBoard, Sparkfun's 3-axis IMU-based autopilot board
"Will there be a UAVDevBoard 3? It seems the next version of ArduPilot is in the works, just wondering if the next UAVDevBoard is in the pipeline.

If its not too late I would like to see one with flat gyros, and more R/C inputs and ouputs.
Keep up t…"

JC replied to Frank's discussion Ublox GS407
"I got a GS407 from sparkfun last month that was bad. It would not get a GPS fix indoors or outdoors. They replaced it with this GPS which is nearly identical, (the GS407 was out of stock). I hooked it up and got a GPS fix in less than a minute."

JC commented on Tim Trueman's blog post Want to test code with the simulator X-Plane?
"Tim,
What variables are you using for accelerations from X Plane. From the input/output menu I see the angular rates but not the accels."

JC commented on Ryan Beall's blog post IMU nose Dive problem/solution
"Hi Greg

Thats a good point, up elevator can also increase the rate of turn in an aerobatic plane.

Its clear now that turn rate is highly dependant on the airframe. When flying an EasyStar the turn is controlled by the rudder (as apposed to aileron…"

"Hi Michael,

I read the paper (a few times) and the ECF Explicit Complementary Filter seems to be a
promising approach. One thing I dont understand is the rate of change of the angle of attack (equation 11). The author assumes that in a turn, the ra…"

"Adam,
Have you had sucess with that method. I thought timing was inportant to sync the video images because a tv expects an input signal at a specific frequency."

JC replied to William Premerlani's discussion robust estimator of the direction cosine matrix
"I am interested in getting the DCM Lite to run on the parallax propeller. I have a 5 DoF board, is that sufficient to run the DCM lite code?? As I understand the the DCM lite code only estimates pitch and roll, however dont you still need the yaw gy…"
