Abstract Positioning accuracy is closely linked to the dilution of precision (DOP). DOP reflects the geometric distribution of visible satellites in space and enlarges the ranging errors. The new estimations of GDOP, PDOP and HDOP called essential DOP are studied and their properies are discussed. The new defined DOP are determined by the maximum eigenvalue of the corresponding cofactor matrix.
Key words :
positioning accuracy
DOP(dilution of precision)
HDOP
VDOP
maximum eigenvalue
