Was power applied in the hangar beforehand, and if so, was there a fault at that point?

May 15, 2025Novatel lost some satellites. Quality went from 5 down to 1, which is TerraStar down to regular GPS, or 10m instead of 1cm accuracy.
Josh reported he was seeing the GGQUAL drop across the earlier flights. Something to keep an eye on.
