EnvironmentPrecipitation and visibility reducing laser PRS performance — laser confidence 67%. Weighting shifted toward RadaScan and radar correlation.
GNSSStrong multipath detected on GNSS near the structure — GNSS family weighting reduced, INS + DVL elevated.
LocataLocata ground network available with 5 transmitters — GNSS-independent redundancy secured.
