    IMCA publishes introduction to inertial navigation

    Publications // May 1, 2015

    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 used offshore.

    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.

    Jane Bugler, IMCA’s Technical Director explained: “This new document provides a broad overview of INS technology currently in use in surface and subsurface positioning solutions, giving a general overview of the technologies, the applications and a number of important considerations in their use. This is very much a developing area and, as ever, proper planning, preparation and risk assessment is critical to ensuring the successful use of these systems. 

    “IMCA S 022 does not attempt to provide the reader with an in-depth understanding of the algorithms behind inertial navigation systems, but covers the main components of such solutions and some of their strengths and weaknesses.”

    Sections in the 34-page publication look at INS technology. Application of INS technology for positioning; INS aiding techniques; current limitations of INS solutions; future developments; and there is a useful glossary and definitions section as well as appendix containing details on inertial measurement units (IMU) types, export licensing, and references and further reading.

    IMCA S 022 can be downloaded free of charge for members and non-members alike from the IMCA website at www.imca-int.com and printed copies are available at £2.00 for members and £40.00 for non-members from publications@imca-int.com and from IMCA at 52 Grosvenor Gardens, London SW1W 0AJ, UK.
