Deze spreuk an afbeelding van prins Hendrik der Nederlanden zag ik in het Koninklijk Instituut voor de Marine (KIM), waar marineofficieren worden opgeleid.

Prins Hendrik (1820-1879), de derde zoon van Willem II, werd op zijn sterfbed nog bevorderd tot admiraal, zo lees ik op Wikipedia.

Royal Navy HMS Prince of Wales breaks down off south coast

The Royal Navy aircraft carrier HMS Prince of Wales is limping back to shore after breaking down shortly after embarking for exercises in the US.

It states that, unless the problem can be resolved at sea enabling the warship to continue its journey to the US, it might need to go into dry dock at Rosyth in Scotland early, ahead of a planned inspection in 2023.
The Nato flagship(!) was sailing to undertake training exercises with the US Navy as well as the Royal Canadian Navy and United States Marine Corps.
The warship, built at Rosyth at a cost of £3bn, had a colourful send-off on Saturday as it passed thousands of revellers at the Victorious Festival on Southsea Common.

Nato is not amused ;-)

It is easy to be swept up in news about the #economy, especially these days. In 2020 the world saw the biggest economic contraction since the #GreatDepression; today we are dealing with the highest #inflation since the 1980s. People rarely have time to think about the very biggest questions in #economics. Why did the industrial #revolution begin in the 18th century—and why in western #Europe? Why do so many countries remain poor when some are fabulously rich? And what is work like today compared with the past? All the issues improve your understanding of the news. For the answers, you need to turn to economic #history. Here are five resources to help you understand why we are where we are.

Bizarre #Drone #Swarms That Harassed #Navy Ships Demystified In New Docs "A major release of documents provides the highest level of detail yet about mysterious drone swarms involving U.S. Navy ships off California." ( by Adam Kehoe and Marc Cecotti )

The U.S. #Navy #Seabees with #Naval Mobile Construction Battalion (#NMCB) 5 can now receive #acupuncture #treatments as part of battlefield auricular acupuncture (#BFA). NMCB-5 is the first U.S. Navy deployable command to perform BFA.

Lt. Jeffrey Moy, NMCB-5’s medical officer, and several corpsmen at NMCB-5 can provide auricular acupuncture, which consists of inserting small gold #needles in the ear to treat #pain, #post-traumatic stress disorder (#PTSD), #nausea, and #addiction–such as tobacco cessation.

Gladys West Modelled the Earth So That We Can Have GPS

image

The name Gladys West is probably unfamiliar, but she was part of creating something you probably use often enough: GPS. You wouldn't think a child who grew up on a sharecropping farm would wind up as an influential mathematician, but perhaps watching her father work very hard for very little and her mother working for a tobacco company made her realize that she wanted more for herself. Early on, she decided that education was the way out. She made it all the way to the Naval Surface Warfare Center.

While she was there she changed the world with -- no kidding -- mathematics. While she didn't single-handedly invent satellite navigation, her work was critical to the systems we take for granted today.

Flying High

West had a passion for satellite altimeters. We think of a satellite being a certain height over the surface of the Earth, but that's not really accurate. The Earth's surface isn't a smooth ball. Passing over a hill or a valley means that the exact distance from the surface to the satellite changes almost constantly. Passing over water is another problem. If you want to be precise, all these things matter. And if you want to build a Global Positioning System, you want to be precise.

West modeled the Earth's exact shape based on data from the GEOS satellite. She later became the project manager for SEASAT, which used radar to measure the ocean surface. Her interest led her to work with the IBM 7030 computer to refine models of the Earth known as the geoid. This takes into account things like tidal forces and gravity to compute the true shape of the Earth, rather than simply assuming that it's a perfect sphere. An accurate geoid is an important part of today's GPS and similar navigations systems.

Full Ride

Her family did not have the money to send West to school, so she worked hard to earn a full scholarship. The top two graduating high school students got a full ride and through discipline and her intellect, graduated valedictorian in 1948.

She was excellent in all her subjects but elected to major in math. After a brief tenure teaching, she went back for a Master's degree. Even with an advanced degree, though, teaching didn't pay very well. Despite her trepidation in moving to Virginia during the 1960s, the Navy job offered her a better wage and she stayed in that job until retirement over four decades later.

Legacy

West received several awards during her time at work. In addition, she was inducted into the Air Force Hall of Fame in 2018. The Navy even produced a short video that you can see below.

Of course, many people worked on GPS -- known as NAVSTAR at its inception. It wasn't even the first system of its kind. That honor probably goes to the 1960 Transit project. But all of these systems needed accurate mathematical models of the Earth, and West was a key part of the team that made that happen. Making accurate clocks, keeping them in sync, and shrinking all the components down with a low cost have their own stories and heroes, but for the math, we can thank Gladys West.

We like knowing the stories behind the tech we use every day. We think Gladys West is even more inspiring because of her humble beginnings and the obvious determination and intellect she had to carry her so far. Gladys got her PhD after she retired, but we understand she still prefers to use paper maps.

Want to know more about GPS? We can help. Just want to use it? We've come a long way from $3,000 handheld GPS units.

Systematic data analysis reveals false vessel tracks

Source: https://skytruth.org/2021/07/systematic-data-analysis-reveals-false-vessel-tracks/

The results were alarming. Nearly a hundred U.S. and European naval vessels had track segments with the same AIS pattern as the false tracks of the Swedish navy ships near #Karlskrona. Over the past few months I dug into this data using all available sources to confirm vessel locations and identities. I confirmed false #AIS positions for 15 navy vessels from seven countries, with many more vessels suspected of having fabricated positions.
