@fedosgad,
first off, thank you very much for inquiring and yes any contribution is welcome. This topic is important because the current state does not allow precise positioning using V < 3 RINEX (so GPS, Glonass and GAL possibly)
Great! I'll take to it then.
Created #239
Thank you for your contribution, this will be added to V0.16 that I'm publishing this week end
In RINEX v2 files header records with labels
ION ALPHA
andION BETA
are allowed. They contain coefficients for ionospheric delay calculations for GPS system (GLONASS, which is also allowed in those RINEX versions, does not broadcast any ionosphere-related information and can be safely ignored). Those fields are checked for by header parser but not handled any further (there are TODO notices).According to Navipedia and IS-GPS-200D (Figure 20-4), coefficients are used for Klobuchar model calculations. This model is already supported by library.
IONOSPHERIC CORR
field, which replacedION ALPHA
andION BETA
in RINEX v3, is handled by header parser which presents it as a separateIonMessage
. I propose thatION ALPHA
andION BETA
should be handled in a similar manner, adding aIonMessage
wrappingKbModel
to resultingHeader
.I am willing to make a PR for this issue. It would be my first experience with Rust though, possibly requiring thorough code review (I have previous coding experience in other languages, so maybe it's not that bad). Current developers/maintainers, would you like me to make such a PR?
