Cobham Aerospace Connectivity announces that it has been awarded a contract by the UK MOD’s Defence Equipment and Support (DE&S) to research Advanced Anti-Jam techniques for the protection of navigation signals received from the Global Navigation Satellite Systems (GNSS).  

The contract will see Cobham conduct research to develop means to provide assured and resilient Position Navigation and Timing (PNT) information derived from the GNSS multi-constellation. Cobham was best placed to address the UK MOD’s needs through its extensive background in advanced antenna technology and sophisticated signal processing capabilities. 

GNSS navigation signals 

The research is set against a backdrop of increasing reliance on GNSS navigation signals in the nation’s critical infrastructure and national security and the frequent interruptions of the signals either accidentally or intentionally.

This contract award recognizes Cobham’s status as a major UK provider of anti-jam systems"

The more sophisticated interruptions involve the falsification of the navigation signal information for nefarious reasons such as piracy, civil disruption and military advantage. 

The DE&S-backed research feeds into the company’s goal of taking already developed Anti Jam capability, and developing a miniaturized system capable of providing advanced means of protection of the navigation signals received from the GNSS multi-constellation network.  

CRPA antenna technology 

The anti-jam system will combine the use of advanced Controlled Radiation Pattern Array (CRPA) antenna technology with intelligent digital signal processing techniques not only to ensure reliable and assured navigation information, but also to derive important signal intelligence and domain awareness information regarding the source and nature of the interference and the best means of mitigation. 

Neil Tomlinson, Vice President Sales and Business Development at Cobham Aerospace Connectivity commented, “This contract award recognizes Cobham’s status as a major UK provider of anti-jam systems as well as our long history and deep experience in the areas of navigation antennas and satellite connectivity. We look forward to working with DE&S in this initial phase and subsequent work on this exciting project.”

Which security technology is most misunderstood, and why?
Which security technology is most misunderstood, and why?

The general public gets much of its understanding of security industry technology from watching movies and TV. However, there is a gap between reality and the fantasy world. Understanding of security technologies may also be shaped by news coverage, including expression of extreme or even exaggerated concerns about privacy. The first step in addressing any challenge is greater awareness, so we asked this week’s Expert Panel Roundtable: Which security industry technology is most misunderstood by the general public and why?

Lessons Learned with Vanderbilt: How have you adapted to the COVID-19 pandemic?
Lessons Learned with Vanderbilt: How have you adapted to the COVID-19 pandemic?

With the postponement of tradeshows and events due to the effects of COVID-19, Vanderbilt and ComNet have taken their high quality, innovative solutions online, directly to their customer base. Through an Online Events and Training resource, you can stay connected with the brands’ top resources and products, as well as join upcoming product webinars hosted by their in-house experts. With a majority of the world currently working from home, businesses must respond to this changing landscape. As such, Vanderbilt and ComNet have turned to online resources to share new product demonstrations and other company news. One cornerstone of the ACRE brands approach was the launch of their Online Events and Training resource page. Ross Wilks, Head of Marketing Communications at Vanderbilt, credits this online resource as the anchor to their communicative success with customers at present. “Through weekly webinars delivered by our in-house experts, Vanderbilt and ComNet have embraced more virtual opportunities to continuously communicate to our customers regarding our latest and most relevant products,” he says. “To date, our webinars have covered a wide range of industry topics such as Why Physical Security and Cloud go together, and The most recent developments in card cloning and reader hacking. Attendance to these online events has proved popular and effective in keeping communication with our customer base open and engaging.” Each webinar ends with a Q&A section, as well as follow-up articles on the most asked questions, plus recordings of the webinars being made available to attendees. As such, the webinar approach has proven a receptive approach for Vanderbilt and ComNet. The Online Events and Training resource acts as a one-stop-shop for all virtual information. Overall, the page outlines the brands’ value-added resources for customers, including the ability to request a remote product demonstration, the availability of free online training, 24/7 access to the Vanderbilt webshop, plus the aforementioned weekly webinars. Vanderbilt and ComNet’s business mantra is built on a foundation of customer-focused core values such as empowerment, collaboration, and high performance and Wilks credits this mentality with their ability to keep information flowing to their base during the present pandemic. “The ACRE brands moved early to kick-start online webinars and ramp up awareness of their already existing online training and shopping options. Now more than ever, it is important to keep customers up to date on the latest offerings,” Wilks explains. “Our commitment has always been to make their customer’s security journey the best possible experience, and that is what this Online Events and Learning page primarily focuses on,” he concludes.

What’s new with video management systems (VMS)?
What’s new with video management systems (VMS)?

Video management systems (VMS) have been around almost since the advent of IP cameras. During those years, VMSs have evolved from software that provides basic functionality to more user-friendly systems offering a growing list of capabilities, many of them related to analysing data as well as recording and displaying video. But the evolution is far from over. We asked this week’s Expert Panel Roundtable: What’s new with video management systems (VMS), and what are the new opportunities?
