After the tuning of background error variance and de-correlation length, results from the NMC-method are closer to those of the innovationvector method, and the analysis results are improved.
Kalman filtering method is widely used in data adjustment of dynamic surveying system, whose unit variance is usually computed with innovationvector of parameters and residual vector of observations.
