Kalman Filter GPS + IMU

I know this probably has been asked a thousand times but I'm trying to integrate a GPS + Imu (which has a gyro, acc, and magnetometer) with an Extended kalman filter to get a better localization in my ...

How are units of noise measurement related to units of a sensor's data measurement?

I'm trying to understand how noise is represented for accelerometers, gyroscopes, and magnetometers so that I can match the requirements of my project with the standard specs of these sensors. I ...

Can a mu-metal enclosed compass measure the earth's field?

I am thinking about using a combination of mu-metal, a faraday cage, and spacial separation to reduce magnetic interference from a brushless motor on a compass sensor. The compass will be used to ...

Gyro yaw drift compensation

I'm looking for some kind of filter, algorithm which will allow me to compensate gyro yaw drift using heading of magnetometer. My project requires only yaw measurments and both sensors are flat. Is ...

How to transform raw accelerometer data into the Earth fixed frame to determine position

I have data from a TeleMega and do not understand how to apply the rotation matrix for the accelerometer data so that I can get the more accurate position estimate from my accelerometer. My data comes ...

Adding magnetic field vector to a Kalman filter

I currently have an error state Kalman filter with the state vector $(p, v, q, \omega, a, g)$ where $q$ is the quaternion orientation. I would like to add the information coming from a magnetometer to ...
