Dilution of precision (DOP), or geometric dilution of precision (GDOP), is a term used in satellite navigation and geomatics engineering to specify the error propagation as a mathematical effect of navigation satellite geometry on positional measurement precision. See more The concept of dilution of precision (DOP) originated with users of the Loran-C navigation system. The idea of geometric DOP is to state how errors in the measurement will affect the final state estimation. This can … See more As a first step in computing DOP, consider the unit vectors from the receiver to satellite i: where $${\displaystyle x,y,z}$$ denote the position of the receiver and See more • Circular error probable • GNSS positioning calculation See more • DOP Factors • manually calculating GDOP • HDOP AND GPS HORIZONTAL POSITION ERRORS See more WebOct 30, 2015 · 3 Answers.
