Bo Li · Journal of Xuzhou Normal University · 2009
Analyzing and measuring of observation effectiveness or ill-condition are the preconditions for improving the method and the quality of parameter estimation.In GPS,the relationship between observation epochs is one of the characteristics of observation effectiveness.In this paper,the method for measuring the relation between observation subspaces is demonstrated and analysed in particular,and a good result is got by applying this method to GPS surveying,which provides a better analysis tool for ill-condition or parameter estimation in surveying and mapping.
