I want to extract Almanac data from SFRBX message of UBX via RTKLIB. What changes I need to make in the project and in which files/functions.

tomojitakasu commented 2 years ago

RTKLIB only supports GPS and QZSS almanac. Other systems are not yet supported. Read codes of decode_frame_alm() in src/rcvraw.c and decode_rxmsfrbx() in src/rcv/ublox.c.

Otherwise write your own codes by refering ICDs.

Yes, the ICD describes the bit fields necessary for extraction. It is also a matter of referring to the protocol specification, firmware features, and UBX specifications and configuration.
