In the RINEX 3 format meaning, it says that CO represents the BDS observation data. However, I cannot find the BDS-3 satellite observation data in CDDIS. For example, I find the observation data in 1, January 2021:https://cddis.nasa.gov/archive/gnss/dat ... 1/001/21o/
There is only one RINEX 3.04 file for one station (twtf). What about the other stations?
And in this file, only two BDS-3 satellites (C27,C37) are included, what about the other BDS-3 satellites?
For those two BDS-3 satellites, only one frequency data is observed, what about the other frequency like C7I?
Where can I find the observation data for BDS-3 staellites?

Re: BDS observation data download
CDDIS and the other data centers only archive mixed observation data files. While it is possible to have single observations files, almost all new receivers are multi-constellation and produce mixed observation files – which are also the most useful.
CDDIS is not able to answer which BDS satellites are tracked by certain stations. That would have to be a question to the IGS or the station operators.
