ION GNSS 2010 Awards

The Institute of Navigation’s (ION) Satellite Division awarded Ali Broumandan of the University of Calgary its Bradford W. Parkinson Award at the ION GNSS Conference last month in Portland, Oregon. Dr Todd Walter received the Johannes Kepler Award for his contributions to space-based augmentation systems. The Bradford W. Parkinson Award is granted annually to recognise an outstanding graduate student in the field of Global Navigation Satellite Systems (GNSS), and is presented in honour of Bradford W. Parkinson for his leadership in establishing the US Global Positioning System and for his work on behalf of the Satellite Division of The Institute... (read more)

Improved GNSS Coverage

Veripos announces a major enhancement of its services with an increase in transmission power from Inmarsat’s Atlantic Ocean East Region satellite, resulting in fully redundant High-Power delivery of GNSS augmentation data throughout Europe, Africa and Brazil regions. Running in parallel with Veripos’ existing High-Power satellite delivery service, the upgrade enables enhanced service reception in addition to significantly improved levels of availability and redundancy. The power increase also ensures improved flexibility and independence for users, who now no longer need be reliant upon vessel-borne Inmarsat reception terminals or mini-domes for accessing data from the satellite; instead, small omni-directional antennas can be...

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)

GNSS and Hydrography

A precise navigation system that has been fully operational only since 1995, yet has had such an impact on hydrography… it looks as if the future of these systems will make interesting reading. GNSS stands for Global Navigation Satellite System and has been dominated by GPS. All hydrographic surveyors will know how this has improved their productivity in the last decade. Today GNSS includes GPS and, to a lesser extent, Glonass. In the future it may well include modernised GPS signals, further Glonass, the European-funded Galileo system, and other satellite-based augmentation services. Not only does this scenario mean ‘more of... (read more)

Brazilian RTK GNSS Receiver

GEO TAG Engenharia (Brazil) has introduced the new multi-constellation RTK GNSS receiver GEO TAG MT.Pro. A pair of Trimble's Maxwell 6 chips provide most accurate and precise positioning and navigation and capable of receiving GPS, GLONASS and Galileo (-ready) satellite signals. The MT.Pro receiver is created for professional and precise positioning applications include land/marine surveying, construction and machine control, agriculture and infrastructure monitoring.   The GEO TAG MT.Pro receiver is designed to allow centimetre-level positioning and dual-antenna inputs for precise heading.   Other key features are high-precision, differential positioning accuracy subfoot-level and subdecimetre-level with OmniSTAR; heading accuracy up to 0.05°;...

Entry-level GNSS Antenna

Hemisphere GPS introduces the affordable A325 GNSS Smart Antenna. This new design incorporates professional-level centimetre and sub-metre positioning accuracy powered by Hemisphere GPS’ Eclipse receiver technology and includes L-band and Bluetooth communications support. A325 is a great fit for a variety of applications including robotics, marine, survey, and GIS. A325 accuracies are software scalable to be custom configured for the customer’s specific needs and budget. Users can take advantage of free SBAS sub-meter accuracy or decimetre-level L-band support. For more precise needs such as hydrographic surveying, customers can activate the centimetre-level RTK feature with robust GPS and GLONASS positioning utilising... (read more)
