First INS Class C Type-Approval Certificate For Hyundai-Transas Intelligent Bridge System

The Hyundai-Transas intelligent Bridge System (HTiBS), the result of Transas and Hyundai Heavy Industries joint cooperation, has become the first system in the world to be type-approved as INS class C. Designed in full compliance with IEC61924 standard, it has recently gained the certificate from Det Norske Veritas (DNV). The first installations of Hyundai-Transas intelligent Bridge System (HTiBS) were completed last year in Ulsan, South Korea. Between September and December 2005 the Transas team installed HTiBS onboard the tankers “Pavel Chernysh”, “Captain Kostichev”, “Viktor Titov”, “Yuri Senkevich” and “Viktor Konetsky” constructed at the HHI. ”Viktor Titov“ was selected as one...

Swathe Services Takes Delivery of SBG Ekinox Navsight INS for Customer Demonstrations

Swathe Services has recently added the SBG Ekinox Navsight to its equipment demo pool.  After extensive trials on manned and unmanned vessels operating under bridges, in harbours and offshore for Hydrographic applications, the performance of the Ekinox Inertial Navigation System (INS) has convinced the hydrographic survey services company. Its small compact subsea form factor and weight makes this system light and easy to install with portable sonar systems. The SBG Ekinox Navsight is ideal for shallow water applications. James Williams, managing director at Swathe, explained: “Since we became the distributor for SBG Systems, we have seen a steady increase in sales across... (read more)

Saturn AHRS and INS Systems Available at Offshore South East Asia

Teledyne TSS’ Saturn AHRS and INS (Attitude and Heading Reference System and Inertial Navigation System) it are market ready and the UK-based company will be offering it for sale commercially for the first time at Offshore South East Asia (to be held in Singapore, from 2 to 5 December 2014). The first versions of the Saturn system were previewed at Oceanology International in London in March since when a small number of trial versions have been subjected to regular and demanding use offshore with different types of clients. The trial programme has enabled any glitches and design weaknesses to be... (read more)

Introduction to Inertial Navigation

The increased use of inertial navigation systems (INS), particularly in support of offshore survey, installation and inspection tasks, has emphasised the need for a general introduction and outline of the use of inertial navigation technology for offshore applications. The International Marine Contractors Association (IMCA) has risen to the challenge and published ‘An Introduction to Inertial Navigation Systems’ (IMCA S 022) produced for the association by Gordon Johnson under the direction of the IMCA Offshore Survey Division Management Committee. The document provides a broad overview of INS technology currently in use in surface and subsurface positioning solutions, giving a general overview... (read more)

Technology in Focus: How Does Inertial Navigation Work?

No Longer Dependent on External Signals
In hydrography, we are used to working underwater where no positions are available from satellite navigation systems. In other professional fields, experience has shown that position updates from satellites may not always be available, or are potentially incorrect: examples are unintentional jamming of the extremely weak GNSS signals and signal reflections leading to erroneous positions. With a few exceptions, the future of back-up terrestrial positioning systems is uncertain. And there are also applications for which position updates are necessary at higher frequencies than satellite systems can provide for. The integrity and availability of position updates benefit from inertial navigation technology,... (read more)

Positioning Buoys without Need of Seabed Array

Pre-spud buoy sets have traditionally required an LBL array for a relative positioning accuracy of better than 1m or 3ft. Using Zupt’s inertial navigation system, accurate buoy sets can be delivered without the need to deploy or calibrate an array on the seabed, thus saving significant vessel time. Using a known coordinate from a nearby subsea structure (manifold) Zupt’s INS will stab into a receptacle and align. After this alignment the INS can begin to accurately position buoys relative to this coordinate. Pre-set Subsea Receptacles Zupt has deployed subsea receptacles installed onto simple frames with known offsets that can butt... (read more)

Technology in Focus: Inertial Navigation Systems

Bridging the Positioning Gap
Inertial Navigation Systems (INSs) are a great help in applications where either position stability is of great importance or where bridging (small) positioning gaps is a requirement. To understand INS, imagine you are standing blindfolded in the centre of a long hallway. Then you start walking. You may proceed quickly at first, compensating as needed and covering ground with confidence. Eventually, however, you begin to lose your sense of alignment. This ability to successfully navigate when denied a visual frame of reference, even for a relatively short amount of time, represents our own basic human form of inertial navigation. An...
