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---real least squares estimation for precise GNSS positioning using a modified ambiguity function approach Authors: Krzysztof Nowel , Sławomir Cellmer , Dawid Kwaśniak 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
