I am trying to estimate the orientation of a sensor platform using gyroscope and accelerometer. I am using a
Kalman filter based approach. I integrate the readings from gyro to obtain the orientation about x, y and z axis. This is will act as the process model. I am planning to use accelerometer readings as observation. I know how to estimate the angles of orientation when the accelerometer is reading only gravity, by using acceleration components in x, y and z.
However, when the sensor platform is moving or accelerating (i.e. gravity is not the only acceleration the sensor is reading), can accelerometer provide orientation/ tilt estimation without the help of any other sensor? Can this approach work without using a third sensor when the sensor platform has high acceleration?
