USCGC Healy has a SB2112 a 12 KHz multibeam swath mapping
echo sounder. The displays for the system are in the Electronics/Computer
Lab. The primary attitude (heave, pitch and roll) sensor
is an Applanix POS/MV-320 with a Seatex MRU-6 as backup.
Primary heading is from the POS/MV with backup from
a Sperry Mk5 Gyrocompass by way of the integrated bridge
system. Primary position is taken from a manufactured
string that is built from POS/MV data by the science
navigation computer. Backup navigation is from the Integrated
Bridge System . Sound speed at the keel is calculated
from sea water temperature and conductivity measured
by the installed SeaBird Thermosaliniograph or may be
manually entered. Sound speed profiles are developed
from XBT, CTD, and historical data.
