Inertial positioning precision improvement through sensors denoising by using wavelet functions tuned with DTF method

The paper present a new way to denoise the inertial sensors signals based on the wavelet functions tuned with Directed Transfer Function method. The method is applied in a bi-dimensional inertial navigator, and a GPS system is used to provide the reference signals used in the tuning process. Shown are: the basic principle of the wavelet tuning method, the bi-dimensional navigator theory and implementations, and the experimental testing of the proposed method.
