model line. The vehicles differ by size, depth, endurance and payload sensor conÞ guration: The lightweight and compact RE- MUS 100 is designed for shallow water work in depths up to 100 meters, the mid-range REMUS 600 can operate in depths of 600 or 1,500m and the deep-water REMUS 6000 operates in water depths up to 6,000m. The REMUS AUVs can be equipped with many different in- struments, depending on the model and the intended use. This includes advanced GPS-aided inertial navigation; Doppler ve- locity log; acoustic Þ sh trackers; varying sensors; nitrate and nutrient analyzers; conductivity and temperature monitors; ra- diometers; side scan sonar; bathymetry; bottom-mapping, echo sounder, forward-looking sonar; video camera module; turbid- ity sensors; and electronic still camera with strobe and magne-tometers. All the vehicles incorporate embedded software, including the Kongsberg Inertial Navigation System, which includes a Hon- eywell Inertial Measurement Unit (IMU), the NavP navigation processing suite and a payload processor which initializes and controls all sensors.Since its inception, Hydroid has delivered a continuous stream of products through a highly-efÞ cient and well-organized manufacturing system which allows for volume production of REMUS vehicles, tracking transponders and other system com- ponents. The result is a highly-repeatable system that produces quality products in a timely and efÞ cient manner. HydroidÕs products are backed by the organizationÕs skilled customer ser- vice staff, which provides on-site training, system commission- ing and continuous product service and support.HydroidÕs R&D efforts have focused on enabling AUVs to operate multiple payload sensors simultaneously, enabling the real advantage AUVs offer over traditional survey methods. Re- searchers have also focused on lowering the platformÕs noise ß oor (electrically, acoustically and magnetically), as well as carefully selecting payload sensor frequencies and managing their synchronization. In May 2011 Hydroid passed a Critical Design Review (CDR) to provide Littoral Battlespace Sensing (LBS) AUVs and as- sociated technologies to the Space and Naval Warfare Systems Command (SPAWAR). The Critical Design Review was held to verify that Hydroid complies with design-maturity require- ments and that detailed design preparations are in place to pro-ceed with system fabrication, demonstration and testing. SPARTON SPARTON Sparton is an end-to-end manufacturer that draws on more than 100 years of experience in the electronics and electrome- chanical device industry. A global company headquartered in Schaumburg, Illinois with Þ ve facilities throughout the U.S. and Vietnam. Sparton is a broad-based provider of sophisticated electronics and electromechanical solutions for busi- nesses of all types, its expertise lies in the tightly regulated areas of defense and security, navigation and exploration, and medical. Sparton has contributed to the backbone of our national defense with its best-in-class sonobuoy line of products with over 6 million sold. We are also ISO registered, QSR compliant, and CAMCAS certiÞ ed to ensure the products we build are manufactured to the highest quality level possible. The Tech Sparton Navigation and ExplorationÕs Navigation Sensor products are designed to offer superior performance, providing accurate heading reference to numerous commercial and defense applications. It also develop some of the most sensi- tive specialty hydrophones for general purpose underwater applications and marine seismic acquisition systems, such as oil and gas exploration and sea ß oor mapping. Our designs operate well in all harsh environments that include extreme temperature ß uctuations, high shock, and humidity. It will be introduce its new AHRS-8 navigation sensor in fall of 2012. This sensor is a fully temperature compensated Attitude Heading Reference System (AHRS), individually calibrated over the -40¼ to +70¼ C operating range, providing industry leading heading accuracy in a broad range of challenging applica- tion environments. It utilizes MEMS-based, tri-axial magnetometers, accelerometers, and gyroscopes along with our proprietary, best-in-class AdaptNav II sensor fusion algorithm and NorthTek Development System, enabling the worldÕs only fully programmable navigation sensor. www.seadiscovery.com Marine Technology Reporter 55MTR #6 (50-65).indd 55MTR #6 (50-65).indd 558/2/2012 10:17:12 AM8/2/2012 10:17:12 AM
