My name is Zach; I am an Antarctic scientist based at the University of Adelaide in South Australia. I am currently leading a project that investigates transport pathways taking place to Antarctica and within Antarctica (inter- and intra-regional transport) and am quite interested in acquiring flight data for the Antarctic region. However, i’ve been having quite a bit of difficulty finding information on this topic and so I thought i’d reach out to the FlightAware community to see if anyone has any leads to point me in the right direction.
I believe we do have some extremely limited terrestrial ADS-B coverage there, but your best bet is probably space-based ADS-B data via Aireon if you need something continent-wide. Briefly, ADS-B is position data broadcast by many aircraft over a line-of-sight radio link, which we collect via ground- or space-based receivers.
(the caveat is that it’s showing recent observed flight data, and so coverage will only show up where ADS-B-equipped aircraft recently flew; that’s obviously highly seasonal and the current data sample seems fairly quiet)
