R2 Sonic Brochure - GSE Rentals

Company ProfileR2Sonic was founded in February 2006 by three veteranunderwater acoustical engineers; Jens R. Steenstrup,Mark Chun and Kirk Hobart; with the mission to utilizetheir experience to bring high quality, leading edgeunderwater acoustic products to the private and publicsectors, with focus on customer needs.R2Sonic founders and personnel bring over 25 years ofmarket driven quality engineering design andmanufacturing experience, utilizing “best practice” designand manufacturing process.R2Sonic brings pioneering values to the industry. Withthe launch of the innovative Sonic 2024 and 2022Broadband / Wideband Multibeam Systems, R2Sonic hasredefined the Multibeam market with unparalleledperformance with unique system features and applicationgrowth capabilities.FacilitiesThe facilities are located on the west side of SantaBarbara's high technology area with University of Californiaat Santa Barbara, Santa Barbara Airport and the oceanwithin walking distance. The laboratories are well equippedwith modern instrumentation and software tools necessaryfor the efficient modeling, development and test ofunderwater acoustical equipment.

Systems OverviewSonic ConceptThe Sonic Broadband / Wideband Multibeam Echo Soundersrepresent the latest in advanced underwater acoustictechnology.The Sonic 2024 and 2022 are the world’s first true widebandhigh resolution shallow water multibeam echo sounders. Withproven results and unmatched performance, the Sonic systemsproduce reliable and remarkably clean data with maximumuser flexibility through all range settings to 500m.The unprecedented 60 kHz signal bandwidth offers twicethe resolution of any other commercial sonar in both dataaccuracy and imagery.MotionHeadingSVPGPSWith over 20x selectable operating frequencies to chose fromwithin the 200 to 400kHz band, the user is not limited by twoor three operating frequencies and thus can trade off resolutionand range and effectively control interference from otheractive acoustic systems.In addition to selectable operating frequencies, Sonic systemsprovide variable swath coverage selections from 10° to 160°on the fly, in real-time and across all frequencies from 200to 400 kHz. The operator may also rotate the sector to preciselocation either port or starboard side of the vessel . No otherhigh resolution, high frequency sonar offers such variabilityof coverage and productivity.When a narrow sector is selected, all soundings areconcentrated within the swath for increased resolution oversmall scale bottom features. Wide swath sectors are typicallyused for general mapping or when surveying vertical surfacessuch as quays, breakwaters, dams, pilings or bridge abutmentsas the increased opening angles eliminate need to rotatethe sonar head.30°- 45° coverage, for increasedresolution over bottom featuresSonic system performance is characterized by low internalnoise, high signal dynamic range and true broad band signalprocessing that suppress multi-bounce interference atgreater beam angles.Advanced functions including equidistant beam spacing, rollstabilization and unique automated range, gate and slopetracking functions are also incorporated for both the Sonic2024 and 2022 systems, increasing system overall efficiency.160º coverage, for mapping high up vertical surfaces

ComponentsSonic Wideband Multibeam systems represent new moderndesign and architecture, unencumbered by legacy designs.The heavy, bulky and power consuming topside electroniccomponents that characterize old mutlibeam echo soundertechnology have been eliminated.Sonic 2024The sonar consists of three major components:a compact and lightweight projector, a receiver and a smalldry side Sonar Interface Module (SIM). The extremely lowpower draw of 50W (for Sonic 2024) and 35W (for Sonic2022) makes it possible to operate the systems on vesselbattery power.Unlike other commercial shallow water multibeam echoSonic 2022sounder systems, all processing is embedded in the sonarreceiver, dramatically increasing system efficiency andsimplicity in integration.Third party auxiliary sensors are connected to the sonarInterface module. The sonar data is tagged with GPS time.The compact size, low weight, low power consumption andelimination of separate topside processors make SonicWideband Multibeam systems very well suited for smallsurvey vessel or ROV/AUV operations.Sonar Interface Module (SIM)For AUV integration, apart from the transmit and receivetransducer, the only hardware to be housed on the AUV isan interface board the size of a PC/104, Ethernet ports, andthe provision of isolated 48V DC power.AUV Survey Operation withSonic Wideband Multibeam system

OperationThe sonar operation is controlled from a graphical user interface(GUI) on a PC or laptop, which is typically equipped with navigation,data collection and storage application software. The operator setsthe sonar parameters in the sonar control window, while depth,imagery and other sensor data are captured and displayed by theapplication software. Commands are transmitted through an Ethernetinterface to the Sonar Interface Module (SIM). The SIM suppliespower to the sonar heads, synchronizes, time tags sensor data,and relays data to the application workstation and commands tothe sonar head. The receiver head decodes the sonar commands,triggers the transmit pulse, receives, amplifies, beamforms, bottomdetects, packages and transmits the data through the SIM viaEthernet to the control PC.Sonic 2022 ReceiverSonic 2022/2024 ProjectorGraphical User Interface (GUI)Sonic 2024 Receiver
