A breakthrough MH370 tracking technology that is a digital radio communication protocol called. used Weak signal propagation (WSPR) proves to be accurate when testing, according to the latest blind test evaluations, which raise hopes for a new search.
Aerospace engineer Richard Godfrey invented another new technology called GDTAAA (Global aircraft detection and tracking anywhere, anytime) takes the data from the WSPRnet and automatically feeds it into a flight tracking system.
Tests assessed by AirlineRatings.com included a series of flights in the southern hemisphere where Mr Godfrey was unable to access the actual route or destination.
The most recent test was conducted by former Qantas pilot Mike Glynn and uses a flight operated by a Qantas A330-200 between Samoa and Adelaide in June 202.
A detailed report on the flight can be downloaded here.
Mr. Godfrey said, “For the purpose of the blind test, the important part of the flight for which ADS-B data is not available was covered”.
“The reason for this flight is that there are no ADS-B stations on Samoa or in the vicinity. The further flight tracking to Sydney and Adelaide was carried out without knowing that ADS-B data was available for this part of the flight. “
Mr. Godfrey stated that the test was very instructive.
“When an aircraft enters an area of turbulence, it creates a WSPRnet-Link signal anomaly. In turbulence, the ground speed suddenly changes by about 6 knots over a two minute period and there is a small correction in the track beyond the correction to maintain a great circle orbit, ”he said.
“Turbulence is particularly interesting because at the end of flight MH370 experienced strong winds and probably some turbulence.
“WSPRnet transmissions are spreading further than previously thought.
“The WSPR protocol enables detection at lower signal levels than previously assumed.
“WSPRnet signals are easily recorded over distances of over 20,000 km to the other side of the world. Signals bounce off in several jumps between breaking back from the ionosphere and reflecting off the surface of the earth.
“If the stopover point is calm sea or flat ice, there is little signal loss from reflection. Hops can cover up to 4,000 km and with 10 hops you can go around the world. “
Further testing is now underway with flight routes without ABS-B data and Mr. Godfrey plans to use the technology and much of the insights gained from the blind tests to track MH370 to a more accurate location for a possible search later this year .
Due to the seasons, searches could not be made until the southern summer of 2022/23 at the earliest.
Most likely this would be the US company Ocean Infinity, which calls the search for MH370 a “unfinished business”.
