Although the measured speed or estimated heading angle is smoother and more continuous than the results from GNSS, it never means that DR positioning results are better as it is a relative positioning method and unavoidably exits accumulative error while GNSS is absolute positioning method.
The result of DR has a high performance of short term, and as the vehicle driving, the accumulative error gets bigger and positioning result becomes unusable.
This includes the accumulative error of the ring gage, the probe, and the recorder.
