Innerspace Delivers Survey System

Innerspace Technology has delivered a personal watercraft survey system (PWSS) to the United Kingdom Ministry of Defense and Royal Marines. This PWSS consists of Yamaha XLT800 watercraft Innerspace 455 survey depth sounder Northstar 941XD GPS and TSS DMS25 motion compensator. Integral wiring is via quick disconnects so electronics can be easily removed for use on other vessels. Read More

NovAtel Developing Galileo Receivers

January/February 2003 issueNovAtel Inc. has announced a 220000 euro (US$ 235400) contract award for the initial development phase of the ground reference receiver for the European Galileo program. Work is to be completed by February 2003.The contract was awarded by the European Space Agency (ESA).Galileo is the European Unions global navigation satellite system expected to be in operation by 2008 with up to 30 satellites orbiting the earth. NovAtel and ESA are working toward replacing this interim agreement with a full contract worth 500000 euros. Work under the additional contract would be completed by the end of 2003. Read More

NovAtel Announces OmniSTAR HP Receiver

On July 30 2002 NovAtel Inc. announced its new ProPak-LB global positioning engine the first engine to have access to OmniSTARs new High Performance satellite service. (See IDR June 2002 page 8 OmniSTAR HP Getting 6-Inch Accuracy)The ProPak-LB coupled with the GPS-600-LB antenna delivers decimeter-level accuracy autonomously with the OmniSTAR HP service.This new technology gives the real time kinematic (RTK) user a fully portable system. This is ideal for applications like geographic information systems (GIS) data collection precision agriculture and unmanned systems said Pat Fenton chief technology officer (CTO) for NovAtel.

Boskalis Standardizing on Aquarius

Royal Boskalis Westminster NV has purchased an Aquarius2 GPS receiver and five Aquarius receivers from Thales Navigation Carquefou France for use in their dredge positioning and hydrographic survey operations. Read More

OmniSTAR HP Achieving 6 Inches

OmniSTAR Inc. is in the final testing stages of a new wide area differential GPS service that has been achieving consistent six-inch horizontal accuracy in its test receivers. Named OmniSTAR HP (high performance) the system will be available to users by subscription. The HP GPS correction signals will be broadcast by several geostationary satellites to users throughout the world.This level of wide-area real-time accuracy is a goal toward which the industry has been striving for quite some time. said John Pointon director of sales and marketing for OmniSTAR.

C-Nav System Provides Corrections

Globally Corrected GPS (GcGPS) is a technique for improving the accuracy and stability of the Global Positioning System (GPS). This technique was developed for NASA because they had a requirement for decimeter accuracy in outer space. As a result a totally new concept for differential needed to be developed so they could operate at great distances from any reference sites. The result of this research has proven to be of value to the marine market which does not always have a reference site nearby. It is of particular value to the international operators that prefer to use one system worldwide. This reduces hardware and training costs plus it improves flexibility and safety. The compact hardware design works well for the dredging industry because they operate both large barges and small survey boats on the same project. The cost of spare hardware is reduced because the same system can be used for various positioning needs on a project. This allows an operator to move from vessel to vessel or to another country and still be comfortable with the positioning system. Since base-stations are not required manpower is reduced as well. This system is called C-Nav and it has proven to be a great asset in many areas of the marine market. Read More

EU Votes to Fund Galileo

The European Union is developing a satellite navigation system called Galileo that is expected to be more advanced more powerful and more reliable that the U.S based global positioning system (GPS). After several years of discussion and study the European Council agreed unanimously on March 26 to fund the $3 billion project. Read More

Trimble was one of the founders of Trimble Navigation Limited and served as president and chief executive officer from 1981 to 1998. He guided Trimble to a dominant role in the GPS information technology market. Read More

American Uses GPS for Rock Placement

American Construction Company used a system of three GPS receivers to accurately cover a 2:1 slopt with armor rock. The real-time positioning system is a modification of Lyman Burk's WinOps program. the clamshell dredge |!|Mukilteo|!| with 50-foot beam on a 120-foot barge used a rock skip to place a precise amount of stone in each placement area on the template in the Blair Waterway Tacoma Washington.
