Accelerometers have been used to detect inclination (tilt) angle for decades. When the sensor is stationary, the accelerometer reading will directly represent the gravity vector in the sensor’s frame of reference. Comparing the gravity vector in the sensor frame, i.e., \(\hat{G} \), with the reference gravity vector in the earth frame, i.e., \(G \), (which … Continue reading Using Neblina as an Accurate Inclinometer

Orientation of a moving object in 3D space can be represented by the three Euler angles: Yaw, Pitch and Roll, where Yaw is your direction angle, pitch is your elevation angle, and Roll is your tilt angle. More specifically, if we consider the reference Earth frame with x, y, and z axes representing North, West, … Continue reading Euler angles or quaternion?
