Alternative vs Standard calibration method

Hi,

I have seen many posts where alternative method is suggested over Standard calibration. However, as I understood it, the alternative calibration method implies that you have good trust in your orientation metadata… but isn’t that what accurate geolocation is for (aka you need RTK drone)? So how does Alternative differ from Standard?

And a follow-up question: what setting would you recommend for dense vegetation areas?

Cheers,
