GPS is sooo yesterday.

[capnsensible]

Coming soon...ish, quantum navigation. Coz satellites are vulnerable.

In the words of Private Fraser in Dad's Army... We're doooomed.

Love the example that a train can get lost in a tunnel.

All those paper charts I have onboard, and the frequent practice in using my 2B pencil, will not go to waste.

I'm just imagining all those gnss devotees realising they are as dinosaur as a hand bearing compass fix.

Oh by the time I am sailing I won’t need to buy and learn how to use a gps

Nothing really new, just better inertial platforms. How do you get a supercooled laser on the boat, let alone in your pocket. If you are going to rely on external signals, they are vulnerable in the same way as any such transmission is.

What is new is engineering it towards manageable size. Its happening. Loads on line about it.

High-Tech Quantum Sensors: Navigating When GPS Goes Dark

One of loadsa articles. This one talks about shoebox size. Like everything, if its possible to flog gazillions, they will do it.

must of been in 1992/3 a boat turned up in Vigo had come all the way fro France on his mobile phone(navigation wise)……I still cannot remember the sequence you press the buttons,would Siri or Alexa tell me where I am

But make sure you have a pencil sharpener!!

Garmin watches already do inertial nav with their 9axis sensors and it’s pretty accurate when GPS is lost in tunnels or when swimming. The MEMS might make it more accurate but is only an improvement on the sensor so minor upgrade. The inclusion of gravity maps is clever and again improves incrementally. I don’t think any of us are devoted to GNSS so much as electronic position finding in general. While I take a keen interest in how the position is derived I don’t actually care as long as it’s reliable and accurate.

I cruised the Baltic once with a skipper who had recently navigated his way round the far east using a road atlas. Apparently as it had showed the main lighthouses he was happy with that. Yes....we were boarded by the Russian Navy on that Baltic trip

Reminds me of my maths teacher: " You won't walk around with a calculator in your pocket when you're in work".

I've seen so many versions of this over the years. Calculators, Spellcheck, Internet, now AI. Even ballpoint pens were frowned upon in primary school as they may affect the handwriting in a bad way! The Luddites always try, and they always fail eventually. Planck's principle is so true, change doesn't happen because you convince people of a new idea, it happens because the next generation has different views. Sailing is slow to change because people don't really retire from it so much as to it.

And quite frankly their advice has rung true for me. The ability to do mental and hand written arithmetic has served me well in my career. Often quicker than reaching for a calculator.

 

[lustyd]

I've had the opposite experience. I sit in front of a massive calculator all day so there's nothing to reach for, and my job is helping customers process billions of rows of data daily, which would take more than a lifetime every day to do in your head, although most of the sums are well beyond mental arithmetic. Thankfully I didn't listen to the old teachers

My job for quite a while now has been to sail boats. My old teachers were Brill!

That explains why you get Lat and Long wrong. (-;

Aah as my QS said, Monkey Maths! Basically you work out the approximate answer you expect, as said, the ability to do mental maths. Some of us had to do to work out the decimal point when using a 'calculator ' - for those of an age who remember, the slide rule, gave you the figures but no decimal point.

I’m not saying computers and calculators are wrong, just that we need to select the best tool for the job at hand and sometimes old stuff works just fine
