In Russia we have good official resource containing GLONASS and GPS+GLONASS precise orbit files (ultra, rapid and final) in SP3 format.  

ftp://ftp.glonass-iac.ru/MCC/PRODUCTS/

Unfortunately TBC do not able to import these files.

That would be fine.

Topic update: now IAC ftp-site consist not only GLONASS orbits but multi-constellation orbits also.

Path to Rapid Orbits for GLONASS only:

ftp://ftp.glonass-iac.ru/MCC/PRODUCTS/%YYJJJ%/rapid/Sta%GGGGT%.sp3.glo

Path to Rapid Orbits for all five constellations (GPS,GLONASS,BDS,GALILEO,QZSS):

ftp://ftp.glonass-iac.ru/MCC/PRODUCTS/%YYJJJ%/rapid/Sta%GGGGT%.sp3

But TBC do not import these SP3 files until correction the second symbol into file header. We just need to change the first two symbols from “#d” to “#c”.

After that TBC understand Sta%GGGGT%.sp3.glo files as GLONASS orbits, and Sta%GGGGT%.sp3 files as GPS+GLONASS+GALILEO orbits.
