WSPR Data Analysis - The Search for MH370


WSPR is an acronym for Weak Signal Propagation Reporter. The WSPR protocol was originally released in 2008.

The website WSPRnet states that "The Weak Signal Propagation Reporter Network is a group of amateur radio operators using K1JT's MEPT_JT digital mode to probe radio frequency propagation conditions using very low power (QRP/QRPp) transmissions. The software is open source, and the data collected are available to the public through this site."

In December 2021 British engineer Richard Godfrey released a paper MH370 GDTAAA WSPRnet Analysis Flight Path Report which showed that data from the Weak Signal Propagation Reporter Network could be analysed using Global Detection and Tracking of Any Aircraft Anywhere (GDTAAA) software to portray the flight path of MH370. The 124-page report describes the process.

A more recent 232-page report MH370 Flight Path Analysis Case Study by Richard Godfrey in collaboration with Dr. Hannes Coetzee and Prof. Simon Maskell was published in August 2023.

A link to the website for these reports and more is shown below, and a sample image from the 2021 report is on the right. The image is linked to the website, not the report.

The Search for MH370

Serving the MH370 Global Community


The research conducted by Richard Godfrey et. al. is mentioned in the Wikipedia article WSPR (amateur radio software). The footnotes are of interest, primarily those which support the theory. There are of course sceptics and those who question the validity of the outcome but the incontestible fact is that the flight path maps produced correlate with the official flight path, which relied solely on data provided by Inmarsat, and confirms that flight MH370 ended in the southern Indian Ocean.

Whether the end point of the flight is accurate will only be known when a new search is conducted.
