WSPR data, along with other communication data, could be used to track flight paths of aircraft. However, the accuracy of such technology is unknown.
A network of satellites is used to provide communication services to ships and aircraft worldwide. These communication networks use high-frequency satellite signals and are accessible in even some of the most remote locations on earth.
Richard Godfrey, an aerospace engineer, has developed a new technology called GDTAAA (Global Detection of Aircrafts, Anywhere and Anytime). This GDTAAA software uses the WSPRnet data (Weak Signal Propagation Report) available on the WSPRnet website along with the satellite communication signals to plot a potential flight path of an aircraft.
While neither the satellite communication system nor the WSPR was created to track aircraft flight paths, data from these systems were combined using the GDTAAA software to track the flight path of an aircraft. In the case of flight MH370, reports state that Godfrey claims to have pinpointed the exact location of the debris; however, research on this is ongoing.
Thus, we conclude that WSPR data alone might not detect the flight path of aircraft; however, when clubbed with other systems, it might be possible to determine a potential flight path of aircraft. Until the complete analysis of the GDTAAA system is available, we cannot confirm how accurately WSPR can help determine the flight path of an aircraft.
