WebApr 11, 2016 · The Dilution of Precision (DOP) is commonly used in satellite navigation to quantify the effects of positional measurements precision. Geometric DOP is used to determine how errors in measurements will affect the satellite’s final estimated state. It is defined as: A GDOP of less than 1 is ideal, as this indicates a high confidence of precision. WebDilution of Precision (DOP) measures the relative degradation or reduction in the certainty of a navigation solution based on one-way range measurements from a set of transmitters. Most often, the transmitters are those on board Global Positioning System (GPS) satellites. If four or more of these satellites are in view of a ground receiver, a ... Geometric dilution of precision. These values follow mathematically from the positions of the usable satellites. Signal receivers allow the display of these positions (skyplot) as well as the DOP values. The term can also be applied to other location systems that employ several geographical spaced sites.
