Compact Survey AUV MUNIN Debuted by Kongsberg Maritime Kongsberg Maritime recently launched MUNIN, a nextgeneration Autonomous Underwater Vehicle (AUV) for offshore survey. Kongsberg Maritime?s Subsea Division has combined its experience in developing and manufacturing the HUGIN and RE- MUS AUVs to bring the compact MUNIN AUV to the market, setting new standards for performance and  exibility in low logistics AUV survey opera- tions.The MUNIN AUV is designed to collect high- resolution sonar data geo-referenced by a survey grade positioning system. Capable of providing the same high-level performance and survey accuracy of the established KONGSBERG AUV family, MUNIN is an ef cient, compact vehicle design, providing for easier launch and recovery and the possibility of using smaller launch vessels. MUNIN features a modular structure that pro-vides the ability to install extra batteries to extend operational scope for missions lasting up to 24 hours at depths as deep as 1,500m. Weighing in at less than 300 kg in air, its 34cm diameter and length between 3-4m depending on con guration, places MUNIN as a light, compact and (virtue of its pedigree) capable AUVs.. Despite its small size, MUNIN is capable of carrying a complete subsea survey payload, consist- ing of sensor technology. It features an advanced new rigid design which integrates the navigation systems and acoustic payload sensors in a single mechanical housing, which is factory calibrated and requires no realignment after transport or remobi-lization. The IHO special order (S-44) compliant sensor payload includes a custom version of the EM2040 multibeam echo sounder, 200-400 kHz, 1 degree x1degree beam width, swath 120 degrees in addition to an EdgeTech side scan sonar 230/540 kHz and forward looking sonar with advanced terrain following and collision avoidance. Also included is an NBOS conductivity and temperature (CT) sensor whilst a sub-bottom pro ler and still image cameras can be speci ed.User con gurable, MUNIN?s  exible commu- nications and navigation systems feature an array of sophisticated technology. Communication is via Kongsberg Maritime?s cNODE acoustic command and data link, Wi-Fi and Iridium. The Kongsberg Maritime NavP aided inertial navigation system (AINS) with Honeywell HG9900 inertial measure- ment unit (IMU) feature within the navigation sys- tem alongside cNODE and HiPAP (option), which offer precise, reliable acoustic positioning. In Norse mythology, MUNIN (Muninn) and HU- GIN (Huginn) are a pair of ravens that  y around the world of Midgard, collecting information for Norse God Odin. Kongsberg Maritime AUVs are designed to provide survey operators with highly accurate data, so alongside the existing HUGIN, MUNIN was the perfect name for this next genera- tion survey vehicle. www.km.kongsberg.com www.seadiscovery.com Marine Technology Reporter 55MTR #8 (50-64).indd 55MTR #8 (50-64).indd 5510/15/2013 10:00:11 AM10/15/2013 10:00:11 AM
