Getting velocity from the orientation sensor

[keydigit]

Hi friends,

I have an orientation sensor providing
Yaw (degree)
Pitch (degree)
Roll (degree)
Yaw rate (degree/second)
Pitch rate (degree/second)
Roll rate (degree/second)
Mag x (mGauss)
Mag y (mGauss)
Mag z (mGauss)
Gyro x (degree/second)
Gyro y (degree/second)
Gyro z (degree/second)
Accel x (mg)
Accel y (mg)
Accel z (mg)

Is it possible to get velocity from the sensor?

Thanks in advance.

Velocity caculates as integral of acceleration. Unfortunately, an acceleration uncertainty or zero error results in an increasing velocity error. So it's only usable on short terms and has to be zeroed frequently.

I have tried it, but the error grows with time. I think it's no use integrating acceleration to find the velocity using commercial accelerometer.

Is it possible to get velocity from other data?

How about GPS?
