摘要
在讨论抗差估计与秩亏自由网平差2个模型的基础上,将抗差估计与秩亏自由网联合,建立抗差秩亏自由网平差模型,并且将此模型应用于GPS基线向量网平差。经过实际数据验证的结果表明,此模型能有效地抑制粗差影响。
The model of the robust rank defect free network adjustment was introduced based on the two model of robust adjustment and rank defect free network adjustment, and which was used in the GPS net adjustment, and the test demonstrated that this model not only delete the gross errors but also persists the good properties of rank defect network adjustment.
