On a Measure for the Discernibility between Different Ambiguity Solutions in the Static-Kinematic GPS-Mode

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.
