Abstract :
Calculation of the measurement error covariance matrix is an essential requirement in data reconciliation methods. Based on the practical measurement network, the measurement operator is proposed and is divided into three categories: basic operator, manual operator, compound operator. Then the estimation of measurement operator error variance-covariance is researched in mathematics statistics. Especially at the presence of outliers, the performance of the estimation is discussed further.
