Abstract
During the past decade the integer fixing of the GPS (Global Positioning System) carrier phase ambiguities has been studied in many papers. The available techniques are rather sophisticated regarding the set-up and analysis of the ambiguity search space. Consistently, the number of observation epochs necessary for the unique solution is strongly reduced. As incorrect solutions may occur, it is essential to study their impact on the coordinate estimates and their precision. Thus quality issues concerning the ambiguity resolution techniques are both of practical and theoretical interest
The paper focuses on the theoretical aspects of the near real-time case with short baseline lengths. Measures of a degree of confidence are introduced for the selection of the ambiguity parameters. An approach is sketched for describing the precision of the ambiguities regarding their integer nature. Reliability aspects are considered taking possibly incorrect ambiguity solutions into account. A proposal concerning the interpretation of the results for practical use concludes the study
