just posting some strange acquisition results I've been achieving in Nottingham (UK). How can it be that GAGAN signal (PRN127) was stronger than EGNOS?

Fig. 2: The code search space, definitely an acquisition...
Fig. 3: The SBAS PRNs correlation result hystogram. PRN127 is stronger than PRN120, PRN124, and PRN126?
Fig 4: As a comparison, the GPS PRNs correlation result hystogram...
Fig. 5: And finally, ESA's creature (should I say Surrey's creature maybe?) is still happily transmitting its data... Go Galileo, go! P.S.: The front-end is this time a Rakon GRM6800 (nice piece of hw believe me).
