Ghost ships, crop circles, and soft gold: A GPS mystery in Shanghai - MIT Technology Review, Nov 2019
"A sophisticated new electronic warfare system is being used at the world’s busiest port. But is it sand thieves or the Chinese state behind it?"

"Nobody knows who is behind this spoofing, or what its ultimate purpose might be. These ships could be unwilling test subjects for a sophisticated electronic warfare system, or collateral damage in a conflict between environmental criminals and the Chinese state that has already claimed dozens of ships and lives. But one thing is for certain: there is an invisible electronic war over the future of navigation in Shanghai, and GPS is losing."

What happens when a Royal Navy warship sees a NATO task force headed straight for it? A crash course in Morse • The Register, Jan 2019
Surely, in this day and age, I asked Cdr Harper, there's no need for such antiquated communication methods? The CO enthusiastically replied, referring to the Morse code signalling routine: "It's secure because it's line-of-sight only; we can encrypt it; it's very difficult to eavesdrop on it unless you're inside line-of-sight; it's a valuable naval skill."

He had a point. I got the distinct impression that the Royal Navy values Morse code highly as a matter of professional pride.

Cruising for Higher Throughputs - Northern Sky Research Aug 2018
"From 300 Mbps to MSC cruises announced by Marlink in June 2017 to the most recent 3.2 Gbps of throughput delivered to a Carnival Cruise Line Ship in May of 2018, there are few satellite sectors that are seeing such record levels of growth to a customer’s single location . With over 570 Gbps of throughput growth expected between 2017 – 2027 according to NSR’s Maritime SATCOM Report, what applications are driving this growth? "

July 2018 - Evolutionary Antenna Tech Inspires the Future of Satellite Constellations | Via Satellite June 2018
"Following seven years of development, Phasor’s electronically steered antennas began testing in commercial use cases this year. These antennas are barely 2.5 centimeters thick, and are designed to be conformal in order to look at a wider angle 180 degrees, with dual-beam technology making them LEO and GEO interoperable."

"LeoSat, for example, sees itself as a disruptor in the defense market — which has traditionally relied upon GEO systems."

"By their own admission, Phasor will never be at the bottom of the food chain. And, while the super yachts of the world number in the thousands, fishing boats number in the millions"

"Isotropic Systems aims to be one of the leaders working to connect smaller maritime vessels and flight routes in India, Africa and Latin America. One way to achieve that, they believe, is by reducing the price point of terminal systems by 70 to 90 percent."

Hacking, tracking, stealing and sinking ships | Pen Test Partners
Ship security is in its infancy – most of these types of issues were fixed years ago in mainstream IT systems.

The advent of always-on satellite connections has exposed shipping to hacking attacks. Vessel owners and operators need to address these issues quickly, or more shipping security incidents will occur. What we’ve only seen in the movies will quickly become reality.

Iridium breaks Inmarsat monopoly on maritime safety communications - SpaceNews.com
"The UN certified Iridium Communications to provide Global Maritime Distress Safety System (GMDSS) services, ending Inmarsat’s monopoly on the internationally required service for ships"

"The International Convention of the Safety of Life at Sea treaty requires ships of 300 gross tonnage or more have GMDSS equipment onboard for international trips. Inmarsat had been the sole provider of GMDSS equipment since 1999.

Iridium said it expects to begin GMDSS service in 2020."

LEO constellation rush not a threat to Iridium, CEO says - SpaceNews.com Apr 2018
"Large constellations of satellites planned for low Earth orbit (LEO) present little threat to Iridium’s business despite sharing the same orbit, CEO Matt Desch said April 26."

"Both Iridium’s legacy satellite constellation and its upgraded Iridium Next fleet that is mid-deployment operate using L-band frequencies. L-band is smaller swath of spectrum that can’t offer the same high throughputs as higher frequency spectrum like Ku- and Ka-band, but is known for its robust signal strength, often making it the frequency of choice for safety communications. Most large LEO constellations that have gained significant attention, including SpaceX, OneWeb, Telesat, LeoSat and Kepler Communications, are designing satellites in Ku and/or Ka-band."

"Iridium reported a 14-percent increase in revenue growth for the first three months of 2018 as compared to the same period last year. Money generated from Iridium subscribers, which numbered 996,000 as of March 31 and make up 75 percent of the company’s total revenue base, grew 10 percent."

"Desch said the majority of network traffic going through Iridium is now on the company’s Next satellites, of which 50 out of 66 are currently in orbit. "

"Iridium has since 2014 sought approval from the United Nations’ International Maritime Organization (IMO) to break competitor Inmarsat’s sole hold on emergency maritime communications."

UK to get TVWS regulations by the end of this year - PolicyTracker May 2015
"Ofcom intends to have a licence-exempt regime for use of TV white spaces (TVWS) by December, according to Claire Mack, regulatory affairs manager for spectrum, telecoms and post in Scotland." - "Ferries shuttling between the Orkney Islands have had Internet services via TVWS since September 2014, said CloudNet IT Solutions chief executive Greg Whitton. TVWS technology also links the Glasgow Science Centre to the Waverley paddle steamer, which allows the crew to access online services, said Andrew Stirling, chair of the Centre for White Space Communications. CloudNet's pilot led BAE Systems Maritime to the conclusion that TVWS technology can prove a viable, useful communications bearer in maritime regions, said Bob Willmot of BAE's naval ships division. Future applications could include commercial networks for harbours; offshore oil well monitoring; lifeguard surveillance; and support for search and rescue services."

Yacht Captain Dares Researchers to Trick His GPS, Gets Unwelcome Result | MIT Technology Review August 2013
"University of Texas researchers recently tricked the navigation system of an $80 million yacht and sent the ship off course in an experiment that showed how any device with civilian GPS technology is vulnerable to a practice called spoofing."
