Relevant in the sense that the position of the accelerometer needs to be known wrt to it. It would have been a lot easier if the COM was at the spin axis, then measured accelereation would be directly a function of distance from the center and rotation rate. However, the problem is that it is...

I can make the rigid body spin. I do know the location of the COM of the body in a reference frame attached to the body. The COM was determined when the body was freely moving, by geometric methods. The application, however, requires the body to be fixed to a support joint and then allow it to...

The accelerometers have 3 orthogonal axes of measurements. The orientation of each accelerometer (and 3 axes) can be figured out. Their relative orientation can also be figured out. However, their relative position is not known. Maybe it can be figured out? Can you elaborate a bit. How will...

I want to find out the position of the accelerometer wrt to the center of mass of the body, which I do have the coordinates for. Think of it like this, I place a accelerometer on the surface of a rigid body but I don't know the location where I placed it. I also don't want to measure it from an...

I think you are talking about Dead Reckoning INS solution, which is not what I am trying to achieve. I am not moving the accelerometer alone but the rigid body to which it is attached, is moving with it. I want to find out the position of accelerometer (which is fixed) wrt to the rigid body, not...

Thanks for the answer. The rotation rate is actually being measured by a gyro. I looked at the Euler's equation of motion and I can calculate the Moment (torque) using the rate and moment of inertia, but how will this help in determining the position of the sensor? The sensor is placed at the...

Hi guys, I am just wondering if it is possible to calculate/estimate the location of measurement point on a rigid body? For example, let's say we have a rigid body that is in motion. We attach a sensor, say an accelerometer on the surface of the rigid body. Now can we estimate the location of...
