查询词典 error in observation

In this dissertation, GPS baseline solution precision is analyzed since the following aspects: 1, Different length baselines are processed and analyzed by single frequency model and ionosphere free model. 2, Basing on current single point positioning precision, certain coordinate error is added into fixed points to study the result. 3, Baseline is processed and analyzed with different observation vectors and their lineal combination models. 4, 24 hours observation was divide up to process baseline.

By the modem time series analysis method, based on the ARMA innovation model, under the linear minimum variance optimal information fusion criterion, three distributed fusion steady-state optimal Kalman filters, predictors and smoothers weighted by matrices, scalars, and diagonal matrices are presented for multisensor systems with correlated input and observation noises, and with correlated observation noises. The Lyapunov equations and formulas of computing local filtering, predicting and smoothing error variances and covariances are given, which are applied to compute optimal weights. The corresponding three distributed fusion Wiener state estimators are also presented.
