The reliability of the iPhone's GPS tracking feature was assessed empirically by Perezgonzalez in 20101. The research used an iPhone and a specialized tracking device (Spidertracks) on the same training flight. At the end of the flight, the data collected by both technologies were compared. More specifically, data regarding four flight parameters were correlated to assess the tracking variability of the two technologies. The results obtained (shown in the table below) indicate that the iPhone tracked the four flight parameters as well as the specialized tracking device did.
|Table 1. Variability assessment|
|flight parameter||Pearson coefficient||significance|
|Latitude||0.991||p < 0.000|
|Longitude||0.997||p < 0.000|
|Altitude||0.990||p < 0.000|
|Speed||0.927||p < 0.000|
