Aerospace engineer Richard Godfrey has used an MH370 search aircraft from the Royal New Zealand Air Force on March 28th, 2014 to help validate his new technology called GDTAAA (Global Detection and Tracking of Aircraft Anywhere Anytime).
This new system is based on the Weak Signal Propagation Reports (WSPR) pronounced ‘whisper’ and promises to give a new search for MH370 a more precise location of the Boeing 777 and also as a back up to the extraordinary satellite and drift modelling tracking of the ill-fated jet with 239 souls on board.
The search aircraft was a Lockheed P3 Orion and it is significant as it was one of the very few to spot wreckage in the area which is now believed to be the final resting place of the Boeing 777.
Mr. Godfrey says this validation report is one of many as he builds a compelling body of work before the final analysis of the MH370 impact zone.
Preliminary work suggests that will align with previous satellite and drift modeling work.
Mr. Godfrey says his work on MH 370’s flight path is a working hypothesis. “The MH370 flight path I have proposed is a hypothesis supported by a body of evidence in the form of a large number of position and progress indicators.”
“The working hypothesis will remain valid until someone proves it wrong by presenting evidence that this flight path was not followed. One possibility would be the publication of raw radar data for example.”
Mr. Godfreys’ latest paper builds on work done by Dr. Robert Westphal who holds a doctorate in engineering from one of the foremost technical universities in Germany. Dr. Westphal has worked on radar systems, is a patent holder, and a top-ranking member of the WSPR amateur radio community (KB9AMG rankings).
In 2021 he presented at the international amateur radio scientific workshop HamSCI 2021 on “Geocaching in the Ionosphere”.
Dr. Westphal wrote, “in mid-July 2020 I started working on WSPR passive HF detection as MH370 was still missing and current technology did not do much help to find it.”
“In November 2020 I detected and tracked flight Qantas QF114 from JNB to PER with nice WSPR signals. I posted my experience and got beaten up as usual.”
“People praise invention and innovation as long as it is not within their own zone of comfort and does not hurt their business. But disruptive technologies will do that.
“Richard Godfrey was the only one who listened and gave it a try. I totally support him with regard to WSPR detection and mostly tracking. With regard to tracking, he is more optimistic than I am, but you have to be optimistic on unknown ground.”
Another supporting HF radio technology as an aircraft detection tool is Ari Joki from the Finnish Defence Forces’ Logistics Command, Air Force Systems Division who in a NATO unclassified paper together with the Lappeenranta University of Technology detected an aircraft that crosses a transmission line from Saudi Arabia to Finland.
In simple language, Mr. Joki and Piotr Ptak proposed in 2016 a global air traffic monitoring system based on the existing worldwide network of radio amateurs and DX (long distance) listener resources.
The radio physics is essentially the same as listening to an express train sounding its horn when passing through a station with the seesaw change in frequency due to the Doppler effect. (You can tell the speed of the train and when it is coming towards you and when it is going away from you.)
