A large portion of the hydrographic community came together at the thirteenth Kongsberg FEMME conference in Trondheim, Norway. Participants exchanged thoughts, ideas and experiences on hydrographic-related topics and Kongsberg subsea...

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...

The wide-band high-resolution multi-beam EM 2040 was released at FEMME 2009 user conference in Lisbon (Portugal). The EM 2040 is designed to meet all requirements for shallow water mapping and...

The Mobile & Marine Robotics Research Centre describe their motivation for building their own Smart ROV based on previous survey experience and the preparations they are now undertaking to integrate...

The alignment of the motion reference unit (MRU) is important for the accuracy of a multi-beam survey. The patch test is mostly used to solve angular offsets between the multi-beam...

With increasing accuracies of positioning and multi-beam systems, alignment of the motion reference unit (MRU) is becoming increasingly important. Although most (if not all) multi-beam surveyors use the patch-test to...

The Student Autonomous Underwater Challenge – Europe (SAUC-E) is an annual event providing an opportunity for student-led teams to design and build a small autonomous underwater vehicle (AUV) to compete...

This article is about my thesis project, which I did in collaboration with Auke van der Werf at the Dutch Nautical Academy at Terschelling (the Netherlands). The research for the...

Survey specifications such as the Land Information New Zealand (LINZ) require a specified number of hits on a given target size and a specified overlap in Special Order areas. In...

Kongsberg Seatex, the position reference systems division of Kongsberg Maritime celebrated a significant achievement in the development of its Motion Reference Unit (MRU) today (March 11th 2008) by presenting Subsea...
