GeoRinex Python strange behaviour on a NAV RINEX v3.03

Open GC1102 opened this issue 3 years ago • 1 comments

Hi, I've found your library on Git and it's great. I've been using it for few projects I have and all is ok, but the attached RINEX file (NAV data). All data are set to nan.

MAT100ITA_R_20203360000_01H_MN.zip

Is there any trick to use for it?

Cheers, Gianni

can you try it with the current "main" branch of georinex? This issue may be resolved. In general there are a lot of nan, as any time or variable not assigned for the given SV is NaN.

For me this file is not all NaN.

Example:

>>> nav = georinex.load("MAT100ITA_R_20203360000_01H_MN.zip")

>>> nav["Crs"].isnull().all()

array(False)
G10 = nav.sel(sv="G10").dropna(how="all", dim="time")
(Pdb) G10
<xarray.Dataset>
Dimensions:           (time: 2)
