That's what they are saying. It corrects for its own ground speed, and the only reason why we have any meaningful data at all is that it corrects based on the assumption that the satellite is...

According to ATSB, aircraft systems don't compensate for vertical velocity at all. (Unlike horizontal velocity, which is compensated for, but with assumptions about stationary satellite.)...

We have a bunch of packets at 18:28 with BFOs consistent with being on the northwesterly heading.

There are other possible interpretations - BFOs are strongly affected by vertical speed, so it...

I'm not sure how you get 441 kt (I get ~360), but yes, that's more or less what it means. BFO 88 Hz is in line with later BFO points and it's a good indication that the turn south was completed by...

As the Wikipedia link says, the rhumb line reaches the pole in a finite distance. It is relatively intuitive. When you are moving along the rhumb line, you have to travel fixed distance for every...

But I just came to the same realization as Shadoko - most of the greenish-yellow dots in that screenshot are not tracks but pixelized text labels.
