BLUNDER TEST AND ROBUST SOLUTION OF VARIANCE COMPONENT ESTIMATION FOR HELMERT TYPE

LIU Changjian MA Gaofeng (Institute of Surveying and Mapping, Information Engineering University, 66 Middle Longhai Road, Zhengzhou 450052, China)  
Blunder test shows that the results of variance component estimation for Helmert type also contain gross errors and the gross errors will probably be transformed when observations contain blunders in this paper. To avoid interacting between blunders and stochastic model errors, the solution of variance component estimation for Helmert type is introduced base on double factors equivalent prior and is improved at the same time.
