There are some issues with the uncombined PPP using the BeiDou satellite system

[ChunboLiu777]

After completing the configuration, I used the sample file ppp_mgex_gbm.conf, changed "pos1-ionoopt = IF" to "pos1-ionoopt = UC", and then ran the command: "PPPAR -C ppp_mgex_gbm.conf -S GEC -M PPP-KINE -A 0 -L 0". The program continuously reports the error: "residuals validation failed... ...", but when BeiDou (C) is removed from the command, the solution works normally.
