## 3 Results and Discussion
### Results
#### 3.1.1 Step 1
Method \(A\) had differences smaller than 10 cm for more than 75% of the time. Method \(B\) had most differences in the range of 1-10 m. Compared to method \(B\), method \(C\) had a larger fraction with differences smaller than 0.5 m and periods of no solution. Method B had a larger fraction of inappropriate integer fixing. Method \(E\) had no solution for about 70% of the time and all differences were larger than 1 m. Table 5 shows the statistics of the differences for the periods when integer fixed ambiguity solutions were computed and Table 6 shows the statistics of the differences for the periods when real number float ambiguity solutions were computed. \begin{table}
