The Minimum Value of GDOP in Pseudo-range Positioning
Fangling Zeng · Fire Control and Command Control · 2009
This paper discusses the imprecision of computation of minimum GDOP value,points out the deduced GDOP minimum value can't be acquired because the eigenvalue connected with clock error is limited in value range.This paper gives the common equation of GDOP minimum with different number of stations.It also details the distribution of stations when GDOP reaches the minimum value.
