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)

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)

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)
