Not really. My algorithm just needs atan2. Its a flight tracking algorithm which calculates velocity of the aircraft from the messages it broadcasts. EDIT: >

Like I said, I have zero knowledge in assembly. And what you are talking about "vector manipulation" is totally beyond me ;) Just doing this part took a lot from me. :D Maybe someone knowledgeable enough will be kind enough to write an improved implementation.

If it just needs atan2, it is not in the category described by the comment that you're replying to.

  Sorry, I might have misunderstood something. But OP said - " if you are computing sin/cos after atan2,", and I don't need any sin/cos computation after atan2. Just the atan2.

    Right, so your situation doesn't fit the condition being described.

Are you writing a server for ADS-B mode S multilateration? eg: https://github.com/mutability/mlat-server https://github.com/mutability/mlat-server ?
- agnivade 9y ago
  Yes, something like that. It doesn't do multilateration yet. But processes ADS-B and Mode-S messages.
