NL resolution from the forward filter (top) and backward filter (middle) for G09, G16, G23 and G27. Red and yellow curve denote the ambiguity-float results in the forward filter and backward filter, respectively. The green curve is the respective ambiguity-fixed resolution. The bottom figures show the results of integration for G09, G16, G23, and G27. The light green curve denotes the integrated ambiguity. The range of x-axis is 3 h
