Don't need to.  I just looked at the file with ubxtool:

    ubxtool -f  scatter1m_f9p_mnt.raw -v 2


It contains both UBX-NAV-SAT and UBX-NAV-SIG messages.  Which are
incomaptible with each other,

UBX-NAV-SAT knows nothing of multuiple signals (l1 & L2, etc.  It is
only for back compatility.  The new UBX-NAV-SIG is for use with the
newer signals.

That is confusing gpsd.  You need to configure your u-blox properly.
