New project from Direction of Travel. Polar Radar is a airplane radar site that monitors flights across the Arctic Circle and Antarctica. People onboard who get within 100km of the North Pole can generate their own certificates.

The site mentions ADS-B as the source for position data.
That technology is perhaps not so useful for this application as ground based receivers will not be close enough for accurate, frequent, reception of aircraft transponder broadcasts.
Even ADS-C position reports via Inmarsat Classic Aero/SBB will be unavailable at high latitudes.
HF-DL would be a good source or downlinks from a LEO ADS-B relay constellation (as operated by Aireon’s payload on Iridium-NG).
@guardeddon I would love to get a better data source that covers this area of the world better. We are using FR24 data at the moment.
@christiannolle
HFDL is a good source, readily received with an SDR.
Inmarsat GEO satellite coverage for aero drops out at high latitudes plus you’d need to acquire C-band air-to-ground link for full ADS-C position reports and receive from all four satellites for full coverage.
Iridium AMS(R)S air-to-ground is Ka-band and I believe the service link is very localised to TPN sites.

However, it’s a nice idea for a bit of entertainment.
