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)

Universal GNSS Receiver

Hemisphere GNSS (Canada) has launched the R330 GNSS receiver, developed as a versatile positioning system. The device delivers positioning through a variety of differential correction methods including SBAS, L-Band, Beacon and RTK. The R330 GNSS receiver combines the functionality and front panel display of all previous R-series products. Customers can start with sub-metre positioning accuracy and upgrade the receiver with subscriptions that add functionality and improves performance capability to centimetre-level accuracy. To provide the most reliable solutions, R330 is capable of tracking multiple frequencies and multiple constellations including GPS and GLONASS. According to Hemisphere, users can switch between the various... (read more)

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)

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)
