Geometric dilution of precision for bearing‐only passive location in three‐dimensional space
Electronics Letters, 2015 Geometric dilution of precision (GDOP) is a measurement of localisation accuracy in bearing‐only passive location. However, the current GDOP expression is available only for two dimensions; while GDOP is widely adopted in spatial application, consequently, the explicit GDOP expression in three‐dimensional (3D) space using the Cauchy‐Binet formula is ...

Geometric dilution of precision for GPS single-point positioning based on four satellites
Journal of Systems Engineering and Electronics, 2008 Abstract To improve the positioning accuracy in GPS point positioning, the geometric dilution of precision (GDOP) including HDOP, VDOP, TDOP, PDOP is commonly considered. The properties of the DOP for the GPS satellite navigation system are studied and the coordinate system is improved in order to decrease the amount of variables.
