A CANONICAL THEORY FOR SHORT GPS BASE-LINES .4. PRECISION VERSUS RELIABILITY

This contribution is the last of four parts and deals with the link be tween baseline precision and ambiguity reliability. It is shown analyt ically how and to what extent the baseline-ambiguity correlation is re lated to the gain in baseline precision, to the Volume of the ambiguit y search space, and to the impact of potential integer ambiguity biase s. Also, an ambiguity DOP measure is introduced together with its clos ed-form formulae for the three different single-baseline models.
