Project Description
The REMUS (Remote Environmental Measuring Units) 100’s are autonomous underwater vehicles manufactured by Hydroid, Inc. Two vehicles serve as mobile assets for the SATURN observatory. They have a maximum operating depth of 100m. They are presently equipped with upward/downward ADCP’s for current measurement and Doppler-assisted dead reckoning, long baseline (LBL) and ultra short baseline (USBL) acoustic navigation, GPS, and Iridium communications. In addition to standard YSI Inc., thermistors and conductivity sensors, both vehicles are equipped with SBE 49 FastCAT CTD’s. Acoustic navigation uses 1–4 transponders (20–30 kHz). Maximum operating speed is about 4.5 kts, but limited to about 2 kts while operating in currents. Range depends on vehicle speed, maximally about 100 km.
