摘要/Abstract

摘要：

针对大型GNSS基线向量网的特点,在改进的相关观测抗差估计RECO方案的基础上采用并行计算技术进行相关抗差估计的并行计算(简称“并行抗差估计”),并给出了可行的解算步骤。通过算例分析,验证了大型GNSS基线向量网的并行相关抗差估计,不仅有效抑制了观测异常对参数估值的影响,而且显著提高了计算效率。

Abstract:

According to the characteristics of large-scale GNSS baseline vector network, the relevant observations robust estimation model which is based on RECO scheme is improved by parallel computing. A feasible process steps are also presented. Using the improved model, a numerical example is given. It is demonstrated that the large-scale GNSS baseline vector related robust parallel estimation not only can inhibit the influence of the outliers to the parameter estimates, but also significantly improve the computational efficiency.

Key words: dependent robust estimation, GNSS, baseline vector network, equivalent weight matrix, parallel estimation
