Successful ambiguity resolution is the key to all high-precision GNSS applications. The probability of correct integer estimation, also known as ambiguity success rate, is a measure by which the success of ambiguity resolution can be predicted. The success rate depends on the integer estimators used and on the strength of the underlying GNSS model.

The Ps-LAMBDA software enables users to evaluate the ambiguity success rates for their application. The software only needs the ambiguity variance matrix of the ambiguity float solution as input. The success rates can be computed for integer least-squares (ILS), integer bootstrapping (IB) and integer rounding (IR). In evaluating these success rates, the users can also choose between Monte Carlo based evaluations or lower and upper bounds of the ambiguity success rates.
