Britain has signed a £900 million ($1.135 billion) deal to buy a part share of satellite operator OneWeb, a low-Earth orbit constellation in-the-making, designed to provide global high-speed broadband services. There had been speculation that the government intended thereby to generate its own satellite-based navigation signals, as it has been shut out of Galileo security signals by its Brexit move. Some satnav experts quickly dashed that notion, but others demonstrated that it just may be possible.

Since 2015, controlled reception pattern antennas (CRPAs) have come onto the market for civil applications where the need to counter increasing GNSS signal jamming and spoofing has grown exponentially. Highly classified and previously available only to authorized military users, these powerful — and unfamiliar — components expand protection for critical infrastructure. All systems incorporating them should be tested for revamped vulnerabilities. This is how.
A free webinar on Wednesday, March 25 from 1:00 PM – 2:30 PM Eastern Daylight Savings Time addresses the topic “GNSS Vulnerability Testing and the Controlled Reception Pattern Antenna (CRPA).”

Previously, controlled reception pattern antennas (CRPAs) were only in the military domain, and highly classified. The need to counter increasing GNSS signal jamming and spoofing in the civil realm has brought CRPAs into limited use there as well. How to test for their efficacy in product design and development?
A free webinar on Wednesday, March 25 from 1:00 PM – 2:30 PM Eastern Daylight Savings Time addresses the topic “GNSS Vulnerability Testing and the Controlled Reception Pattern Antenna (CRPA).” This technically rich, educational event is sponsored by Spirent Communications and Inside GNSS.
