iPhone GPS reliability

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 are shown in the table below for each of the four flight parameters of interest.

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
