Downloads fail however:

BDS_URLS = ['ftp://pub:tarc@ftp2.csno-tarc.cn/almanac/YYYY/tarcDDD0.YYalc','ftp://pub:tarc@ftp2.csno-tarc.cn/almanac/YYYY/convDDD0.YYalc']

INFO: Skipped followed by ERROR: Error while handling ftp://...

I tried to remove the beidou from the script but there wasn't an easy way to turn download off by uncommenting.

The other sites seems to download.

@GoatWildernessCollective Doesn't matter, data is redundant and it works anyway. Also, turning the download off for a single constellation is a matter of changing a single line of code in get_almanac (or adjusting the URLS list in case of ephemerides), but you don't have to do that at all.
