The expected position error in many cases is far from feasible to be estimated experimentally using real satellite measurements which makes the model-based position dilution of precision (PDOP) crucial in positioning and navigation applications. In the following text we derive the relationship between PDOP and position error and we explain that this relationship holds as long as the model for the observation errors represents the true sources of errors.
