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)

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 Compass Module

Canada-headquartered Hemisphere GNSS has launched its Crescent Vector H200 GNSS compass module, a high-performance receiver for heading, positioning, heave and attitude. Vector H200 is designed for professional marine, navigation and land applications in challenging and dynamic environments. Vector H200 uniquely processes L1 GPS and GLONASS signals to deliver heading, greater positioning reliability, and better performance in challenging environments. Through using two separate antennas, Hemisphere GNSS’ patented Vector technology computes the heading and pitch or roll angle while stationary or in motion. Vector H200 can compute heading accuracy to 0.02 degrees using a 5 metre antenna separation. A variety of differential... (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)

High-Performance GNSS Receiver

Magellan has showcased its latest dual-frequency GNSS receiver at the Oceanology International 2008. The latest advance from Magellan processes GPS and GLONASS signals via Magellan's patented BLADE technology to offer fast centimetre-level accurate performance for demanding high-precision applications.   With its new RTK solution, Magellan brings to the market a unique blend of technologies which increases RTK availability. They take advantage of currently available GPS, GLONASS, and SBAS signals, but also be comfortable knowing that you can upgrade your receiver to meet the evolution to future constellations (Galileo).   Magellan's BLADE (Baseline Accurate Determination Engine) technology employs a unique algorithm...
