COMPARISION AMONG SEVERAL SEQUENTIAL ADJUSTMENT METHODS
多种序贯平差方法的比较

The sequential adjustment probably makes parameters and their posterior covariance fallible if there are anomalies in the prior parameters and the measurement data.After discussing robust estimation for sequential adjustment,the adaptively robust sequential adjustment is conducted,and these methods are compared.A GPS network is calculated respectively by several sequential adjustments methods to test their effects of robust estimation.
