CCSDS BCH and CLTU coding

[Yotam Rabin]

Hi everyone! 
I'm trying to design a gnuradio based ccsds transmitter using the ccsds 231.0-b TC standard.
My design requires the use of BCH (63,56) code and the encapsulation of the data inside the CLTU packet.  

Does anyone have any experience with this in gnuradio ? I wasn't able to find any implementations of such coding. 

Any help would be greatly appreciated
Thanks,

Yotam
