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)

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)

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)

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)
