GLONASS, GPS and GALILEO Present and Future Aspects

Global Navigation and Hydrography is the theme of this issue. GALILEO has received a ‘green light’, GPS has planned some important improvements and GLONASS has entered on a significant development programme. Time for HI to ask experts involved in each GNSS for their opinion on certain topics and finally to put the question: ‘What is in it all for us surveyors?’ The experts interviewed are: Dr Vidal Ashkenazi (GALILEO), Dr Keith McDonald (GPS) and Dr Boris Shebshaevich (GLONASS). The planned GALILEO-system involves some discussion in connection with already present GNSS systems and some of our questions had a political aspect.... (read more)

Motion Sensor Performance

Direct Comparison Using 2005 Common Dataset
Integral components of a swathe bathymetry system are the motion and heading sensors. The current trend is to offer a system that combines both components in one package, either as an aided inertial sensor or as two sensors linked by component software. The quality of these inertial sensors has a direct effect on the quality of the final survey. This paper compares five leading available sensors, concluding that they produce markedly differing results. Most surveyors when purchasing or specifying a particular inertial system for a project will base their decision on information generated by the manu-facturers, which often shows all... (read more)

The Rocknes Casualty 2004

A Chartmaker’s Retrospect
The MV Rocknes (about 17,000 GRT (Gross Register Tons), draught approximately 10.5m, see Figure 1), en route from Eikefet, Norway to Emden, Germany, hit a shoal in Vatlestraumen, Norway on 19 January 2004. The vessel carried a pilot from the Norwegian Coastal Administration (NCA). Soon after the grounding the ship capsized with the loss of 18 crew. 12 crew were rescued. Norwegian Hydrographic Service (NHS) was blamed for not publishing its knowledge of a presumed new shoal in the Vatlestraumen. Three subsequent lawsuits were necessary to establish a credible explanation of the accident’s root causes. 10 years after the serious... (read more)

Satellite Navigation

Over the last twenty years Global Positioning System (GPS) receivers have revolutionised navigation. Integrated devices are capable of providing time, position, height, direction, heave and attitude, to accuracy of a few nanoseconds time, 1cm position or 0.01-degree heading. This article explores the future development and implications of Satellite Positioning. Satellite Positioning dominates navigation at sea, in the air and on land and is now available in our cell phones and wristwatches. How it currently works was explored in the October 2006 issue of Hydro international in an article titled ‘Satellite Positioning’ (pp 35-39). But how will it work in the... (read more)

Fugro's CEO: “Working for a Safer and More Sustainable World”

Interview with Mark Heine
Mark Heine is chairman of the board and CEO of Fugro, with the headquarters in the Netherlands. Fugro is the leading and largest specialised survey company in the world, serving the full lifecycle of assets, and calls itself a Geo-data specialist. For the avid mountaineer Heine, challenges are never too high to take on, not even heading up a multinational in transition, from a company largely dependent on the oil and gas industry to one that wants to co-create a sustainable and liveable world. We talked to Mark Heine about leadership style, strategies for finding new employees, and Seabed 2030. About this ambitious project, Heine says ‘Commercial companies need to work together with NGOs and academia to make this happen.’ Mark Heine is chairman of the board and CEO of Fugro, which is headquartered in the Netherlands.

Sea Level Rise Modelling

In a Caribbean Small Island Developing State
In 2009, a research project was implemented to study the potential socio-economic impacts of climate change upon coastal communities in Canada and the Caribbean. Grande Riviere in Trinidad and Tobago, one of the study sites, is an important nesting site for leatherback turtles. Turtle watching, part of eco-tourism conducted in that part of the country, is an important source of income for the community. Any significant rise in mean sea level may negatively impact the turtles’ nesting sites and consequently negatively impact Grande Riviere’s socio-economic wellbeing. Hydrographic and topographic surveying techniques and GIS were used to construct spatial models that... (read more)

Ocean Survey - The World Market

Over the past thirteen years Douglas-Westwood Limited has produced a series of occasional techno-economic studies of the Ocean Survey industry. This latest, The World Ocean Survey Report 2004-2008 aims to review the most significant recent developments, value markets and provide a forecast for the period 2004 to 2008. In practice, it is very difficult to precisely define the boundaries of the subject of ocean survey as for example some definitions may include survey of the major navigable waterways. Furthermore, commercial survey & positioning (S&P) contractors’ activities range into other areas, including the operation of assets in non-survey tasks, such as... (read more)

Hydrography in the Far East

Interview with Associate Prof. Dr Mohd Razali Mahmud
There is much current activity on the hydrographic scene in the Far East region; the area was hit by the Tsunami, 26th December 2004. The region is also on the doorstep of China, a country undergoing enormous economic growth and a consequent growing market for hydrographic surveying. Have developments in China any other consequences for the hydrographic community in the Far East? Associate Professor Dr Mohd Razali Mahmud, Head of Hydrography, Institute for Geospatial Science and Technology of the Universiti Teknologi Malaysia (UTM) agreed to be interviewed by Hydro international (HI) on the matter. Please give our readers a summary... (read more)

The Conference was held in the main hall of the Auditorium Ranier III in Monaco from 23 to 27 April 2012 which had been conceded to the IHB by the Government of the Principality. In that same building were put in place two exhibitions: the IHO Member States (IHO MS) cartographic exhibition (27 exhibitors) and the Hydrographic Industry Exhibition (27 Exhibitors including UKHO). Responding to the invitation of the IHB, the following MS sent their research vessels: China (RV Qian Sanqiang), Russia (RV Donuzlav), Spain (RV Tofiño) and the United States (RV Bruce Heezen). France sent the Frigate La Fayette.... (read more)
