摘要
在基线解算采用随机软件时，仅能获得单一基线向量的协方差阵。在这种情况下，平差观测量应如何选取是该文讨论的问题。
When adopting stochastic software in the solution of base line, it can only obtain the covcariance matrix of a single base line vector. Under this condition, how to select the adjustment observable will be the problem to be discussed in the paper.
