Spectral ambiguity of Allan variance

نویسنده

  • Charles A. Greenhall
چکیده

The phase-noise spectrum determines the Allan variance by a well-known integral formula. It is shown here that unique inversion of this formula is not possible in general because the mapping from spectrum to Allan variance is not one-to-one. A necessary and sufficient condition for two distinct phase spectra to have the same Allan variance is given.

Time stability characterization and spectral aliasing Part II: a frequency-domain approach

We showed in Part I of this paper [1] that the estimation of the white-phase noise level of a sampled signal may be achieved with variances even if the sampling frequency is far lower than the high cut-off frequency. In Part II, the effects of spectral aliasing for the different types of noise are reviewed. The responses of the Allan variance and the modified Allan variance for high-frequency n...

Modeling Inertial Sensors Errors Using Allan Variance

It is well known that Inertial Navigation Systems (INS) can provide high accuracy information on the position, velocity, and attitude over a short time period. However, their accuracy degrades rapidly with time. The requirements for accurate estimation of navigation information necessitate the modeling of the sensors' noise components. Several methods have been devised for stochastic modeling o...

Allan variance applied to time series baseline results for GPS-based deformation monitoring applications

Deformation monitoring systems seek to detect constant movements with time, varying movements with time or a sudden movement. A slow movement at the millimetre level will not be detected by comparing consecutive session solutions due to inaccuracies between sessions. However, comparisons over several sessions, or days, or weeks, could highlight slow consistent changes. The Allan variance is int...

Using Allan Variance to Determine the Calibration Model of Inertial Sensors for Gps/ins Integration

In this research, Allan Variance analysis is used to identify the stochastic error sources existing in inertial sensors and to determine the corresponding noise parameters. According to the noise parameters, the power spectral density (PSD) function of the stochastic error sources can be determined. The differential equation descriptions for individual stochastic errors are then derived for two...
