I have somewhere a paper (which i cannot find currently, sorry) that used a dish trained at one of the EGNOS satellites and used it as the only source for timing. IIRC the results were promising, but not spectacular. The problem being that all the ionospheric and tropospheric effects limited the performance, which also could not be averaged over several satellites. Hence most people today focus on whole constelation systems and try to get the best out of that, even under multipath and jamming.
