Guidelines for GNSS ­Positioning

A joint OGP & IMCA Revision of the 1994 UKOOA Guidelines
The original UKOOA Guidelines for the use of differential GPS in offshore surveying, published in 1994, were widely used within the offshore survey industry. In 2005, the International Oil & Gas Producers Association (OGP) took over the custodianship of the guidelines from Oil & Gas UK (formerly UKOOA). At that time it was recognised that the original guidelines needed updating in order to reflect the rapid technical advances in satellite navigation technology of recent years and to maintain the purpose and relevance of the original guidelines. OGP and the International Marine Contractors Association (IMCA) agreed to work together on the... (read more)

Community-sourced Positioning Project

The TeamSurv consortium offers sailors and powered boaters the opportunity to join a community that collects and shares depth information recorded by vessels' existing depth sounder equipment. Depth data, along with the vessel's position, are automatically logged and stored in real time, either by a software utility running on a Windows PC or using a dedicated hardware logging device. At the end of the voyage, the logged data is uploaded to the TeamSurv website. Submitted data are combined and processed, using unique algorithms, by TeamSurv and are corrected for actual or predicted water levels and other factors so as to... (read more)

LBL Underwater Positioning

Long baseline (LBL) positioning has many applications both commercially and in research, from surveying a ship hull to positioning offshore platforms in deeper waters. The technique consistently provides accuracies in the order of decimetres over large areas, independent of depth. Recent advances include the integration with other acoustic techniques or with inertial navigation systems for greater levels of accuracy. Since navigation by GPS isbased on electromagnetic signals that cannot penetrate water, subsea positioning requires a different approach. As sounds waves travel through the sea they alternately compress and decompress the water molecules; these compressions/decompressions are detected as changes in pressure.... (read more)
