| Definition | The Dilution of Precision (DOP) or Geometric Dilution of Precision (GDOP) is the coefficient of the uncertainty which relates the uncertainties in radial and velocity vectors. It is a key index to optimize the configuration and to assess the positioning precision. First defined in Chapman et al, (1997) On the accuracy of HF radar surface current measurements: Intercomparisons with ship-based sensors. Journal of Geophysical Research Atmospheres 1021(C8):18737-18748. | |
