NettetIt is shown that the integer least-squares principle maximizes the probability of correct integer estimation. Sharp and easy-tocompute bounds are given for both the ambiguity success rate and the baseline’s probability of concentration. Keywords.

The success rate and precision of GPS ambiguities
Nettetsquares In this case, the integer least-squares estimates of the ambiguities are found by means of a simple rounding of the least-min (8) a i (aˆ i a 1)2/σ2 1 (aˆ m a m)2/σ2 m, with a i ∈Z squares estimates to their nearest integer. This simple rounding scheme does not produce the required integer least-aˆ i NettetGPS Solutions Vol. 22, No. 1 Mixed integer---real least squares estimation for precise GNSS positioning using a modified ambiguity function approach article Mixed integer-- … change spinner mop head
