摘要
Abstract
The research of variance-covafiance propagation of nonlinear least squares adjusted parameters must keep in step with the development of nonlinear least squares adjustment in this area. The existing results are inclined to the variance-covariance propagation of observed values, and precision of the nonlinear least squares adjusted parameter is seldom concemed. This paper gives the theory and calculating formula for variance-covariance propagation of nonlinear least squares adjusted parameters for different types of observed data. The results of example prove that this method is effective and reliable.关键词
