Abstract
The modeling of double-difference GPS phase observations for short baselines leads to the condition that the ambiguity parameters must be integers as long as residual biases can be neglected. However, not always is the combination of those integers the best choice which lie closest to the unconstrained least-squares solution. Thus we may investigate quite a number of different ambiguity solutions and try to discern between them by means of statistical testing.
Since the discernibility between different hypotheses turns out to be basically a function of the respective non-centrality parameters we are able to define a corresponding measure, called AMBIGLOP, which reflects the geometric behavior of the satellites over time with respect to the instantaneous baseline under investigation, and which can somehow be related to the more popular measures like PDOP or RDOP, for example.
