© Springer International Publishing Switzerland 2015. Integer ambiguity estimation and validation are crucial steps when solving the carrierphase based GNSS model. For the validation, different ambiguity acceptance tests have been proposed.

Therefore it is better to use model-driven critical values such that it is guaranteed that the failure rate will not exceed a user-defined threshold.
