Mike Glynn, a former Qantas pilot, has set a new blind test for GDTAAA and the WSPRnet data. The departure was on 3rd June 2021 at 03:28 UTC (actually leaving the runway) at an approximate position of 13.830 °S 172.000 °W as this is not shown on ADS-B. The aircraft...

New MH370 breakthrough tracking technology passes another validation test. I have used an MH370 search aircraft from the Royal New Zealand Air Force on March 28th, 2014 to help validate this new technology called GDTAAA (Global Detection and Tracking of Aircraft...

In a previous paper entitled “Using the WSPRnet and Inmarsat Satellite data in the search for MH370” published on 14th April 2021, I showed how the weak signal propagation report network (WSPRnet) and the Inmarsat satellite data can be used in conjunction with...

In addition to their existing other work, CAPTIO have studied a thousand Inmarsat compatible straight line trajectories crossing ARC2 from latitude 5.8°N down to 3.35°S. A straight line trajectory ( i.e. constant speed, great circle from Arc2 crossing point) minimises...

The Weak Signal Propagation Report (WSPR) is based on a protocol invented by Joe Taylor. WSPR is a digital radio communication protocol designed for weak signal transmission. WSPR uses frequency-shift keying and forward error correction to reliably send data tens of...

Geoffrey Thomas of www.airlineratings.com has written a guest article on new credible evidence defining where to search for MH370. Although this area has been partly searched before, the underwater terrain is very challenging. At the 7th Anniversary of the...
