UTONOMYREMUS <strong>100</strong>NavigationTranspondersFour small, lightweight transpondersare supplied as reference beaconsfor the vehicle during operation.The transponders are preset tolisten for a specific signal, whichis transmitted by the vehicle,andthen immediately reply. The vehiclemay then easily compute the slantrange to the transponder.Acoustic DopplerCurrent Profiler(ADCP)/DopplerVelocity Log (DVL)The specially designed Teledyne RDInstruments ADCP/DVL can beconfigured to include both downwardand upward looking transducers,allowing for bi-directional currentprofiling, 3-D bottom track, altitudemeasurement and highly accuratedead reckoning navigation input. Thealtitude measurement, when coupled withthe vehicle’s position and depth, alsoprovides seafloor bathymetry.Conductivity &TemperatureThe vehicle is equipped with amulti-parameter sensor sonde,which includes temperature andconductivity. Temperature informationis stored in the REMUS <strong>100</strong>’s harddrive for plotting a profile of thewater temperature in the searcharea. Conductivity and temperatureinputs are used to accuratelydetermine the speed of sound inwater, which is used to increasenavigational accuracy.NavigationThe REMUS <strong>100</strong> navigates during amission using Long Baseline (LBL)and Dead Reckoning (DR). Theon-board computer automaticallydetermines the preferred method,and can vary it through the mission.REMUS RangerThe REMUS <strong>100</strong> vehicle carries an emergency transponder; completely independent ofthe vehicle’s other systems that may be interrogated at any time. The Ranger is a small,waterproof deck unit, designed to give the operator the ability to monitor the vehiclesprogress, via its transponder while the mission is underway. The Ranger consists of a highlyportable deck unit connected to a small, towed transducer. The front panel display indicatesthe real-time range to the vehicle in meters and/or is used to send selected commandssuch as “abort mission” or “come home” to the vehicle during operation.
