GNSS DOP support for NANU

Apologies if this turns out to be s silly question, but does the DOPComputer support Notice Advisory to Navstar Users (NANU) records in a .sof file alongside SEM almanac data in .al3 files?

I’m sorry but the answer to your not silly question is no, the DOPComputer doesn’t handle autonomously NANUs or SOF.
These files have to be processed before to set the list of effective GNSS satellites to take into account.

Thanks for the quick resposne. Does OreKit have support for reading NANUs from .sof files?

No, Orekit doesn’t yet.
But you can ask for it as a new feature on the forge at, or may be someone could contribute a SOF parser ?
