Data centricity is an architecture formed from participants that communicate only with the data infrastructure. Data-centric communication systems contrast with object-oriented systems (where objects communicate), message-oriented systems (where participants send messages to each other), and service-oriented architectures (where participants connect to services).

Participants in data-centric systems are decoupled from all other participants in time, space, and flow. Data-centric connectivity is also called a “databus,” defined by the Object Management Group (OMG) Data Distribution Service (DDS) standard.

Databases are also data centric. However, a database implements data-centric storage, while a databus implements data-centric communication. The key difference: a database searches old information by relating properties of stored data. A databus finds future information by filtering properties of the incoming data.

Thales Exec: Connected Aircraft and the New Cyber Vulnerabilities | Via Satellite

As commercial aircraft increasingly become connected to the larger Internet of Things (IOT), the potential for safety risks also rise, the head of Thales’ business operations in the United States said on Wednesday.

There have already been hacks of aircraft and aviation-related systems, including In-Flight Entertainment (IFE) systems, data communications between pilots and ground-based controllers, and airline operations systems that in one case in Europe caused flight cancellations, Alan Pellegrini, president and CEO of Thales USA, said.

Airlines Grapple with New Customer Demands on Connected Aircraft | Via Satellite

The world of In-Flight Connectivity (IFC) is entering a new era as airlines and suppliers prepare to grapple with new customer demands. David Bartlett, Chief Technical Officer (CTO) of Panasonic Avionics, told the Passenger Experience Conference in Hamburg, Germany this week that the traditional ways of providing content to airlines is changing.

“The traditional way with a server on the plane doesn’t scale. So a cloud based solution is the way to go. We can tailor content for every flight. We want to provide a predictive capability. The industry is moving very fast. People’s preferences are moving very fast. The important thing is we have to learn more cohesively as a industry,” he said.

Free-space optical communication systems complement traditional Radio Frequency (RF) solutions, bringing the internet speeds of terrestrial fiber optics to space.

Using laser technology, optical communication systems offer a much narrower and more focused beam than traditional RF links, resulting in higher data rates, more capacity, greater security and smaller, lighter and more affordable terminals.

Triggering the new forever war, in cyberspace | Military & Aerospace Electronics

Since cyber forces are in “persistent engagement” with one another, U.S. Cyber Command must dive into the fight, actively contesting adversaries farther forward and with more agility and operational partnerships.

The vision, however, ignores many of the risks and how to best address them.

Most importantly, the vision does not even recognize the risk that more active defense – in systems and networks in other, potentially friendly nations – persistently, year after year, might not work and significantly increases the chances and consequences of miscalculations and mistakes.

Military Drones Prove Vulnerable to GPS Jamming

Maritime security experts have warned for years about the hazards that simple GPS jamming methods could pose to merchant shipping. According to American defense officials, the Russian military is deploying a weaponized form of GPS jamming that is effectively blocking some U.S. drone aircraft operations over Syria – and is even affecting drones equipped with anti-jamming technology. As more and more operators contemplate the deployment of autonomous vessels and aircraft in the maritime space, the vulnerability of high-specification military hardware to GPS jamming may pose a cautionary tale.

So far, the attacks have only affected small surveillance drones, four officials told NBC News, not the U.S. Air Force’s armed Predator and Reaper models. They declined to discuss whether any of the small aircraft had gone down as a result of jamming. High-end drones like the Global Hawk, Predator and Reaper are equipped with inertial navigation systems, which do not depend upon external signals for positioning, in addition to their GPS receivers.

The past year revealed the dark side of social networks and brought the largest government-sponsored attacks to date. It also has shown that blockchain and quantum computing are neither immediate threats or panaceas for security, said experts.

“The threat picture is getting darker,” said Kirstjen Nielsen, Secretary of the U.S. Department of Homeland Security (DHS), in a keynote at the event that attracted nearly 50,000 registrants. “In each morning briefing, I see digital threats multiplying faster than we can keep up.”

Test Tool Finds Ethernet Wiring Errors | EE Times

Because you need to connect to both ends of a cable to test it, the LANSeeker needs two devices: an active base (which, of course, is portable) and passive remote.

The remote module attaches to the base unit for safekeeping, sliding off to the top. That’s convenient for storage and transport of the tester — it becomes one piece.

I’ve used other cable testers that are two separate pieces, and this design is better because you’re less likely to misplace the remote unit. Pulling the remote from the base was, however, a little harder than I expected, though reattaching it was smooth. Figure shows the remote receiver separated from the base transmitter unit.

Book on GPS History Reveals Innovation, Test Challenges | EE Times

The history of GPS development, in less-technical terms, provides meaningful insight into this fortuitous blend of disparate technologies and the people who made it happen.

It’s easy to be unaware of the difficult path behind “how we got here” when there’s a technical advance that so quickly becomes a routine, fully accepted part of daily life. This is true of the Global Positioning System (GPS), which took only a few decades to go from a just-proven concept to a key building block for both countless mass-market and highly specialized applications. (Note that the first launch of the “official” GPS system satellite occurred about 40 years ago in June 1977.)

That’s why I enjoyed the recently published book “Pinpoint: How GPS is Changing Technology, Culture, and Our Minds” by Greg Milner, with its interesting history and perspective into the development of GPS

PM Narendra Modi Served An Uncomfortable Message By IMF Boss Christine Lagarde

Christine Lagarde said she had told Prime Minister Narendra Modi that he did not mention the women of India enough in his speech to the summit and “it’s not just a question of talking about them”.

“I was hoping he would have said a bit more. Wish he had talked a bit about girls and Indian women,” she had then told NDTV.
