This is at a Master's level work, and I count on every trick in the book being thrown at me, including crashing the blooming thing into a wall for an impact, spins, rolls, and dives. A snap roll wouldn't surprise me at all or something similar. I switched majors from ME to a EE so I am taking a...

Sampling rate is only 200 Hz. I have just been integrating simply by addition of previous gyro reading multiplied by sampling time: angle = angle + gyro*.005. This is obviously a very simple and most likely very wrong way of doing things. So I shall look into advanced integration techniques. I...

D. H., Thanks for the suggestions. The application is to track a UAV for about 30 seconds without using control feedback and to accuracy of about .5 meters while expecting the vehicle to fly no more than about 200 meters, so essentially autonomous UAV tracking. I am expecting the device to have...

Thanks for the reply D H. I think I get what you are saying for the most part, so forgive me if I am a bit thick in my reply: I have been using simple Rotation matrices from SO(3), in order to rotate accelerometer data using the angles that I presented above. I iteratively rotate the...

So I have been trying to figure out some orientation data that I gather from a triaxial gyroscope, and figure out my orientation using only initial conditions and angular velocity from the gyroscope's current axes. The data is all relative to the current orientation, so if I rotate the device...

yep, you are done.

correct

that is the metric system, you are using english units. So they are both correct. if you are in an engineering course you might want to keep the english system as a course requirement.

Not to be critical, but check the number you posted. you have posted that you need to do ch 1.2 #4 (b). that is ch 1.5 #4 (b). So either typed it wrong or you are on the wrong problem, b/c I am in a course using the same book. If you are doing the correct problem, then I can say I have no...

the a is more accurately 32.185 ft/s^2, but that is the gravitational acceleration on earth.
