MH370 GDTAAA Analysis

MH370 GDTAAA Analysis

The GDTAAA WSPRnet MH370 Analysis Preliminary Findings place the crash location at 33.177°S 95.300°E just 6 nm East of the 7th Arc. The report can be downloaded here This preliminary report provides a summary of the key findings from the MH370 flight path analysis...
How Can WSPR Help Find MH370?

How Can WSPR Help Find MH370?

During the timeframe of the MH370 flight between 7th March 2014 16:00 TC and 8th March 2014 01:00 UTC there are 60,627 WSPR links over distances greater than 1,000 km, thanks to many dedicated radio amateurs world wide. There is an average of 224 WSPR links every two...
Maldives Aircraft Sighting

Maldives Aircraft Sighting

A number of eye witnesses on the island of Kuda Huvadhoo in the Maldives reported seeing a large low flying aircraft early in the morning of 8th March 2014. Blaine Gibson travelled to the island and interviewed the eye witnesses whose reports appeared credible....
AMSA MH370 SAR Flight

AMSA MH370 SAR Flight

Flight data kindly provided by the Royal New Zealand Air Force (RNZAF) has been used to check what detections and tracking of aircraft are possible using GDTAAA and WSPRnet data in the southern Indian Ocean back in March 2014, when MH370 disappeared. This is the...
WSPRnet Propagation

WSPRnet Propagation

A WSPRnet Propagation Technical Analysis can be downloaded here The purpose of this technical analysis is to explain how the propagation of WSPRnet signals is used to track an aircraft. A worked example taken from the Qantas flight used in a recent blind test will be...
GDTAAA Blind Test

GDTAAA Blind Test

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 Tracking Technology for MH370 Search

New Tracking Technology for MH370 Search

A new aircraft tracking technology is nearing readiness for the MH370 search. Significant progress has been achieved in refining a fascinating new technology, Weak Signal Propagation Reporter (WSPR), which is a digital radio communication protocol that is providing...
When Do Whispers Shout

When Do Whispers Shout

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...

MH370 Final Major Turn(s)

MH370 Final Major Turn(s)

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...
Guest Paper by CAPTIO

Guest Paper by CAPTIO

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...
WSPRnet and Inmarsat Satellite data

WSPRnet and Inmarsat Satellite data

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...
