Estimation of probability of lambda failure through employment of lookup table

An apparatus, comprising:

• a processor component configured to access a lookup table that comprises a plurality of result sets from a plurality of Monte Carlo simulations on a plurality of condition sets;
• wherein each condition set of the plurality of condition sets comprises:
• a probability of failure (Pboot-fail) for a boot-strap method for estimation of double difference carrier phase integer ambiguity,
• a ratio test tolerance for a least-squares ambiguity decorrelation adjustment (LAMBDA) method for estimation of double difference carrier phase integer ambiguity, and
• a number of space vehicles (Nsv);
• wherein each result set of the plurality of result sets comprises a probability of lambda fail (Pλ-fail) and a probability of lambda reject (Pλ-reject) for one condition set of the plurality of condition sets;
• wherein the processor component is configured to employ the lookup table to estimate a value of Pλ-fail for given values of Pλ-reject, Pboot-fail, and Nsv .
