### angular velocity output of IMU

I am reading the paper On-Manifold Preintegration for Real-Time Visual-Inertial Odometry. There is one paragraph about IMU model. I have two questions. The first one: An IMU commonly includes a 3-...

### Ways to estimate the drift rate of the gyrometer

I found not so much literature to the topic, this is why I ask here. Does someone know some ways to estimate the drift rate of the gyrometer. I was thinking about basically two approaches. One would ...

### Gyro measurement to absolute angles

Let us assume we have a gyro that is perfectly aligned to a global frame ($X,Y,Z$). From what I know the gyro data give me the angular rate with respect to the gyro axis ($x,y,z$). So let's say I ...

### Angular velocities and rotation matrices

Let us assume I have an object O with axis $x_{O}$, $y_{O}$, $z_{O}$, with different orientation from the global frame S with $x_{S}$, $y_{S}$, $z_{S}$ (I don't care about the position). Now I know ...

### Axis of rotation via IMU

Using an IMU (gyro, accelerometer and magnetometer), as found in most smartphones, can I detect the differences between tilting the device, say forward, along different (parallel) axis positions? To ...
