The indicator must be operable without any communication link between the rover and the reference station. Two common existing GPS quality measures are combined: firstly, the SIGMA model, which is a signal intensity-based weighing scheme reflecting the actual signal quality, and secondly, the ambiguity dilution of precision (ADOP), which is an indicator of the geometric strength of a constellation. Together, these two established indicators form the newly developed ADOP+. In the first part of the present work, a calibration is conducted in order to obtain the parameters for the SIGMA model. In the second part, the ADOP+ is derived and implemented. A practical test is performed on a motorcycle in order to validate the concept. The ADOP+ is proven to be meaningful and well performing within the empirical case. It is able to predict the success of phase ambiguity resolution in the majority of situations.
