Teledyne TSS Launches AHRS and

INS Systems

Following a two-year development pro- gram, Teledyne TSS previewed a com- plete new family of advanced AHRS and INS (Inertial Navigation and Atti- tude and Heading Reference Systems) named Saturn at OI ’14.

The Saturn family is based upon fi ber- optic technology developed and manu- factured by Teledyne TSS. The family also incorporates advanced digital sig- nal processing and algorithm design to deliver a highly accurate and reliable product to meet the demanding needs of the marine market. All units are com- pact, lightweight in both air and water and provide a unique alternative to com- petitive products.

As the fi rst tranche of a comprehensive product development program, there are four versions of the Saturn family with two basic grades of accuracy available in both surface and subsea confi gura- tions. To summarize, the Saturn 10 has a heading accuracy of 0.1° sec. lat. RMS, with a pitch/roll accuracy of 0.01°.

Heave accuracy 5% or 5cm.Saturn 30 has a heading accuracy of 0.3° sec. lat.

RMS with a pitch/roll accuracy of 0.2°.

Heave accuracy 5% or 5cm.

Both subsea versions use titanium cas- ings rated to 4,000m as standard. teledyne-tss.com iXBlue Announces RAMSES Launch iXBlue launched the next-generation medium-frequency RAMSES, a long synthetic baseline positioning system for ROV/AUV navigation, offshore oil and gas support, metrology and other demanding subsea applications. The system can be tightly coupled with iX-

Blue inertial navigation systems (INS) and delivers extreme precision and ro- bustness in challenging acoustic opera- tional environments. Available in MF and LF versions (medium frequency for most applications and low frequen- cy for ultra-long range applications),

RAMSES is part of iXBlue’s inertial- acoustic solutions for underwater posi- tioning and navigation. www.ixblue.com

Kongsberg Launches Gyrocompass

OI ’14 was the launching point for a new range of Gyrocompass products based on MRU technology from Kongsberg

Maritime’s sensor Powerhouse, Kongs- berg Seatex. The fi rst model available is MGC R3, which includes three Ring

Laser Gyros (RLGs) and three linear ac- celerometers providing highly accurate readings suitable for demanding appli- cations such as seabed mapping.

MGC R3 complements the well-es- tablished and comprehensive range of

MRU models (Motion Reference Unit) for high-end offshore and survey ap- plications. MGC R3 has INS capabili- ties with embedded north seeking al- gorithms and outputs both raw (gyro and accelerometer) and processed sen- sor data including heading, roll, pitch, heave and position. www.km.kongsberg.com 6HQVRUV6\VWHPV6HUYLFH

FSI’s HMS-620 Bubble Gun

TM ultra-portable seismic system is perfect for small boat shallow-water surveys.

Its proven technology provides superior signal penetration through coarse sand, gravel tills, and other diffi cult to penetrate sediments; and it operates in salt or fresh water. Data collected with the HMS-620 rivals that of much larger, heavier, and more expensive air-gun, boomer, and sparker systems. Its compact size makes it easily deployable without the need for heavy machinery. It runs on either a small generator or optionally on marine batteries, and it does not need an air compressor or other support infrastructure.
