I have an Inmarsat demodulator working for the lower speed control channels. I am writing a program to decode the traffic, but this is not a trivial task. Think on the order of 1000 lines of C. It is "almost" working, I am hoping for valid output in the next week or so, depending on my free time.
My program is currently a standalone program, but once it's done it could conceivably be converted to one or more gnuradio blocks.
I suggest the following document to give you background on the channel specifications for Inmarsat:
The demodulation is fairly easy, read the spec document and the channel characteristics are pretty well described. My gnuradio demodulator is based on the GMSK demod block. I'm using a home brew patch antenna, and the LNA4ALL low noise amplifier.
