Dear Sergei Markochev,
Concerning my results at the first attempt, we have 7 training/test sets, so plenty of ressources to tweak and tune our models. I started to have good results on these test sets two weeks ago but I did not make a submission. I felt like it would hint my opponents that a ~50m accuracy would be achievable. As the competition is soon ending, I made a submission just to know where I was.
Since 2018, I have been working with ADS-B data provided by OpenSky Network. As it was pure ADS-B data, these data did not contain any “nanosecond receiving date” from several receivers. Again, my research work was only on climbing data with consolidated ADS-B data, not nanoseconds timestamps from several receivers.
Concerning my links with OpenSky Network, I applied to get ADS-B data in 2017 on their website https://opensky-network.org/ like anyone can or could. I only exchanged a few emails with OpenSky staff, mostly regarding the exact meaning of the variables inside the data they shared with me. I think a lot of researchers are in such a case, dozens, maybe a hundred.
Concerning my eligibility, it is up to the organizers to decide. Should they rule I am not eligible, I would accept their decision but I worked dozens of hours on this competition like anyone participating in this competition.
Best regards,
Richard Alligier
