Claim One:
1. A method for estimating a probability of failure of a least-squares ambiguity decorrelation adjustment (LAMBDA) method, wherein the LAMBDA method is used for estimation of double difference carrier phase integer ambiguity, the method for estimating the probability of failure comprising the steps of: selecting a plurality of condition sets, wherein each condition set comprises a probability of failure (P boot-fail ) for a boot-strap method of estimation of the double difference carrier phase integer ambiguity, a number of space vehicles (N sv ), and a ratio test tolerance for the LAMBDA method; running a plurality of Monte Carlo simulations on the plurality of condition sets to obtain a plurality of result sets, wherein each result set comprises a probability of lambda fail (P λ-fail ) and a probability of lambda reject (P λ-reject ) for one condition set of the plurality of condition sets; creating a lookup table with the plurality of result sets; estimating a value of P λ-fail for given values of P λ-reject , P boot-fail , and N sv through employment of the lookup table.
