I am using invensense gyros with an ardupilot mega for a quadrotor imu/controller.
Attached are the reading from my gyros which seem to be very noisy, perhaps from vibrations.
Is this amount of noise seem normal to you? I think it's much to noisy and
Read more…I am using the code Jordi released here, and i'm getting about 2 meter peak to peak readings when the sensor is absolutely steel. I expected much better results, the manual says 9 cm resolution. what good is it if the noise is 20 times as much?
Read more…Which input (IN0-IN7) controls the flight mode(autonomous or manual) by changing the mux control?
thanks!
Is it possible to program both GPS to communicate with the same satellites?
Hi
I'm getting a very noisy speed measurement (unusable noisy...). I suspect the pitot tube for being responsible.
I am using DIYdrones pitot tube. the silicon tube is about 40 cm (a little more the a foot) and the metal pipe is located at the wings le
Is there a date?? I really need a couple of them... :)
thanks!
Read more…I have just finished soldering my new Arduimu gyros to the board but they seem not to work.
I checked all the contacts, and all the voltages seem fine. but the voltage on the out pin is constant at 1.8V and doesn't change when the board is rotated.

Hi guys,I'v spent the last few days studying Kalman filters in IMUs and there's one thing I can't understand:the order in which I integrate the speeds from the gyros is important. Different orders will give different results. How is this problem solv
