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)

Challenging GNSS Vulnerability?

Or better not?
The reasons for GPS vulnerability due to interference are explained and reasons behind the system being designed as it is today discussed. In addition, consideration is given to why some new developments in future satellite signal structures must meet certain constraints due to United States and NATO national security issues. The impact of GPS on all maritime operations is immense; one would hardly know what to do were it ever to fail in what it generally does. But unlike in many fairy tales, real life may be a little harsher than ideal; a simple little box may deny our access... (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)

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)
