RinexLoader does not support BDS-3 signal as specified in Rinex 3.04
RinexLoader does not fully support version 3.04 of the file format. It misses all BDS-3 signals that are specified in table 9, page 21 of the format.
Some trigrams exist (for example C1P) but only associated with GPS and Glonass frequencies. Some trigrams are completely missing (for example C7Z).
