GNSS and Hydrography

Multi-interview (1)
None of us can anymore imagine hydrographic work without satellite positioning. Improvements in performance since the first launch at the end of the70s have made it suitable for more and more applications and developments are ongoing. A GPS modernisation programme is upgrading both satellite performance and ground infrastructure, the Russian Glonass modernisation programme will upgrade performance to GPS level, Galileo test satellites GIOVE A and B are performing well and due to become available in a few years, and there is increasing augmentation system coverage. Time for Hydro International to question some experts on these developments in relation to our... (read more)

Upgradeable GNSS Receiver

The C-Nav3050 GNSS receiver has been designed to uprade the C-Nav3050 from a single-frequency receiver to a powerful geodetic instrument. The C-Nav3050 performance upgrade path allows users to adapt to changing requirements via simple software upgrades avoiding the need to purchase costly additional hardware.   C-Nav3050 is powered by the new 66 GNSS channel Sapphire circuit board making the receiver uniquely suited for real-time applications including precise positioning, offshore surveys and engineering, DP input, hydrography (exceeds highest IHO standards), coastal and military applications, marine airborne reconnaissance and survey.   Interference suppression (both in-band & out-band), multipath mitigation, and measurement accuracy...

Apex GNSS Positioning Service

Veripos has extended its range of services with the introduction of Apex, a new high-accuracy positioning solution. Complementing the company's existing Ultra service, Apex similarly uses precise point positioning (PPP) methods for correction and/or modelling of GNSS error sources. Each service operates independently, providing continuous decimetre-level accuracies. For delivery of the Apex service Veripos operates its own orbit and clock determination system (OCDS) which derives real-time corrections for all GPS constellation satellites using proprietary algorithms. Data is taken from the company's global network of more than 80 reference stations, with multiple and redundant OCDS systems running in parallel from two... (read more)

Veripos GNSS Visualisation Software

Veripos, UK, has extended its range of proprietary software with the introduction of Quantum, a suite of visualisation modules providing a user interface for delivery of next-generation services and features. Designed to operate with all current Veripos positioning options including its latest Apex5 multi-constellation PPP service, the software has been developed with significant input from a wide range of users by way of simplifying any system configuration while easing methods of interpretation. Other advances include integral diagnostic functions for simple identification of any operational problems together with indications of likely solutions. Visualisation modules can also be operated independently without affecting... (read more)

GNSS Antenna Patent

Hemisphere GPS was awarded a patent for the Broadband Aperture Coupled GNSS Microstrip Patch Antenna (U.S. Patent 7,429,952). "What makes this antenna design unique is its use of dielectric layers," states Dr. Michael Whitehead, Chief Scientist for Hemisphere GPS. By using dielectric layers, Hemisphere are able to reduce interference from external sources, such as radio frequency (RF) signals and improve multipath mitigation.   Hemisphere GPS customers are already enjoying the benefits of this innovation. This technology is currently employed in the A20 and A30 antennas as well as in the A100 Smart Antenna. These antennas all boast superior accuracy, sensitivity,... (read more)

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)

Training and GNSS Handbook

During the Oceanology International event in the UK, Skilltrade and N-Sea welcomed professionals and students at morning survey training sessions. Skilltrade also received several questions about certification and competence, as the market seems to be becoming increasingly aware of the new requirements. GNSS Handbook As the GPS Handbook had completely sold out, Skilltrade decided to create a fully revised edition: the GNSS Handbook. Back in 2007, only GPS was fully operational whereas nowadays there are also Glonass, Galileo and BeiDou. The first part of the revised handbook focuses on the general layout of GNSS, its errors and its practical use.... (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)
