3000 DEEP Digital Side-scan Sonar

L-3 Communications Klein Associates has changed the L-3 Klein System 3000 DEEP. Recent technological advances have allowed the L-3 Klein System 3000 DEEP to provide better imaging at great ocean depths. The upgraded Klein System 3000 DEEP has specially-designed transducers for operation at 3000 metres depth (or more). The outer housing of the L-3 Klein 3000 DEEP Towfish is fabricated from titanium for optimum pressure tolerance at maximum depths, even during extended periods of operation.     The L-3 Klein 3000 DEEP is designed to transmit data to the topside using standard coaxial tow cable during normal operations. For extended... (read more)

IceBridge Mission Prepares for Study of Arctic Glaciers

NASA's Operation IceBridge mission, the largest airborne survey ever flown of Earth's polar ice, kicks off its second year of study when NASA aircraft arrive in Greenland 22nd March. The IceBridge mission allows scientists to track changes in the extent and thickness of polar ice, which is important for understanding ice dynamics.   IceBridge began in March 2009 as a means to fill the gap in polar observations between the loss of NASA's Ice, Cloud and land Elevation Satellite, or ICESat, and the launch of ICESat-2, planned for 2015. Annual missions fly over the Arctic in March and April and... (read more)

Could Adaptive Pingers Have Aided Search for MH370?

Adaptive Pinger Technology for Undersea Location
Although the number of aircraft lost at sea is not very high, over the past years a number of aircraft have suffered precisely that fate. With the recently renewed search for Malaysian Airlines flight 370 (MH370), one wonders about the technology in the underwater location of aircraft and other high-value objects. Underwater locator beacons (ULBs or ‘pingers’) are used for this, either on the airframe itself or on the black box. This article proposes making use of technological advancements to allow better detection. Missing Airliners During the initial search for MH370 nearly 4 years ago, it became apparent that better...

Fugro Support Extended in MH370 Search

The Australian Transport Safety Bureau (ATSB) has awarded Fugro an additional contract for the deployment of two specialist vessels as well as equipment and expertise in the deep-water search for the missing Malaysia Airlines aircraft 370 (MH370). Fugro will mobilise its vessels Fugro Equator and Fugro Discovery, both fitted with specialist deep-tow survey systems, for the work.The Fugro Equator has already been involved in the bathymetric survey of the search area since June. Fugro and ATSB expect the Fugro Discovery to begin the deep-tow search late September with Fugro Equator joining shortly thereafter. The search is expected to take up... (read more)

On-board OmniSTAR XP Corrections for POS AV

Applanix's POS AV products support on-board OmniSTAR XP real-time differential GPS corrections using a purpose-built GNSS+L Band aircraft antenna and an embedded BD960 GNSS receiver. Until now, Applanix POS AV users needed to add an external SBAS receiver and mount a separate L-Band antenna on the aircraft fuselage to receive these corrections.   OmniSTAR XP is a Satellite Based Augmentation Service (SBAS) that provides real-time corrections for GPS signals in order to improve positioning accuracy. With the on-board capability and single GNSS+L Band antenna, the benefits of SBAS corrections can be obtained without the inconvenience and extra cost of having... (read more)

Artemis AUV Continues Deepest Bluefin Search

Phoenix International (Phoenix, USA) personnel working aboard Australian Defence Vessel (ADV) Ocean Shield recently completed the latest phase of search operations for MH370. ADV Ocean Shield returned to port on 5 May 2014 to re-supply before continuing the search for the missing aircraft. The search is being conducted using the company’s AUV Artemis working at water depths up to 5,005 metres of seawater, the deepest depth ever achieved by a Bluefin 21 AUV. During this phase of the search operation Artemis recorded over 240 hours of in-water time and surveyed well over 500 square kilometres (nearly 200 square miles) of... (read more)

Discovering H.M.S. Ark Royal

In November 1941 the aircraft carrier H.M.S. Ark Royal was returning from Malta, when it was torpedoed and sunk by a German U-boat southeast of Gibraltar. Its destruction was a devastating blow to the Royal Navy's power in the Mediterranean theatre of war and to the morale of the British people. In October 2002, nearly sixty-one years after it was lost, the remains of the Ark Royal were identified on the bottom of the Mediterranean using C & C Technologies HUGIN 3000 AUV. In the autumn of 2002 the British Broadcasting Corporation (BBC) contracted C & C Technologies, Inc. (C... (read more)

AUV and ROV Technology Plays Key Role in Historic Discovery

WWII Wreck Located in South Pacific
An underwater research and exploration vessel has played a key role in locating a major US aircraft carrier lost during World War Two. The R/V Petrel, owned and operated by philanthropist Paul Allen, discovered the remains of the USS Hornet on the seabed, 5,330 metres below the surface of the South Pacific Ocean near the Solomon Islands in late January 2019. This article looks more closely at the importance of underwater technology in enabling this historic find. The R/V Petrel is an expedition ship belonging to Vulcan Inc, a company founded by explorer and philanthropist Paul G. Allen, co-founder of Microsoft... (read more)
