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 be defined as: Conceptually you can geometrically imagine errors on a measurement resulting in the term changing. Ideally small changes in the measured data will not result in large changes in output l…
