Abstract

Reasonable determination of weights is the key factor in giving full play to advantages of GPS/BD combined system. Generally, Helmert VCE (Variance Component Estimation) is employed aiming at adjusting the variance-ratio between the two heteroscedastic systems. Besides, the precise priori weight matrix can enhance the convergence of iteration methods based on posteriori information, reduce the iteration's times. However, system related errors, together with outliers, influence the estimation, leading to a distorted stochastic model. Therefore, in this paper, based on Robust Helmert VCE and using integrated priori accuracy, taking various error sources into consideration, an initial weighting method for combined system is suggested.
