Initial alignment technology is one of the most important technologies for strapdown inertial navigation system (SINS). The accuracy of initial alignment influences the SINS's navigation accuracy directly. In this work, the analysis of strap down inertial navigation system's initial alignment is approach from a statistic point of view. Liner error models(More)
The factors which influence measurement precision are analyzed here. On the basis of the principle of nice measured drift of differential capacitance sensors and the properties of a transformer electric bridge of changing in real numbers with fine stability, high precision, good sensitivity and wide working frequency range, a measuring scheme, which(More)
