Here's one with the Instinct on my wrist. 

I had turned off the GPS on the Gopro8 to save battery.
I like to record full runs at 4k/30fps, the 8 could only do 43 minutes.

The Gopro 11 battery records 1:15. at 10Hz.

GPS is tough to add to anything.  Gopro eliminated it entirely in the 12. 
All the pro's are probably using separate sensors now.

The dropped 1Hz data points are easy to see on my simple graph line. 
Pretty amazing what those little watches can do.

For a high sample rate, like 10KHz, a system would have about 10 samples per microsecond.

10,000Hz sample rate isn't in my world.  Nor are 10th's of a millionth of a second. 

I'm a simple person.  10Hz means 10 data points per second, each one one a speed, on a graph, per unit time.

The 25Hz RaceBox I linked includes an accelerometer and a G force sensor.  When they fold that into their model, they can get location within 4"
The Seabreeze forums windsurf slalom guys were engineering their own system 15 years ago, and it worked.  Accurate stops and starts.  On the ocean.   

As for location, it doesn't matter to me if my line is off by 6 feet.  I have tested it for location and it's damn accurate.
We were experimenting with locating paddlers in our group if someone was missing.  We were using Google Maps "share my location."  It's free and it works. 
I downloaded my Garmin telemetry into Google Earth and located my position on my downwind line.  It was easily within 6 feet on the few points I checked.
 
All I need are speed numbers, in real time. 
Here are videos using the same model, with imported 1Hz and 18Hz sample rates.
The graph has 10 seconds on the x axis, speed on the y axis.
 
Note the Garmin on my head. That was 2013.  Gopro and Garmin telemetry imported into a model I use now.  That's 1Hz.   

The other video is Gopro 8 telemetry at 18Hz.  Note all the data points in the same 10 seconds? 
More data, more accurate graphs if you drop a point (or 10).   

It's not rocket science.

GPS speed is always inaccurate in short burst since it's purely time/distance with an error band that can go either way. No modern GPS is useful for timing.

The racecar guys have been all over GPS for years.  This tiny unit is 25Hz, Racebox has another system at 50Hz.  The drone guys go up to 100Hz.

Here you see the speed spike right before it goes to zero. I assume this is my body ragdolling across the water and accelerating the watch for a split second giving the false reading. A bit unfortunate that they track split second speed spikes, I'd like something that shows top speed held for 1-2 seconds for better accuracy. Other than that though, love the watch, especially the ability to track miles on my sails.

The graph you posted looks great for what we ask of them.  Spikes like that occasionally slip thru.
They are far more common the more you zoom in on the data. 
I've always been fine with Garmin data, because downwinding doesn't have violent starts and stops. 

That's actually not a split second speed spike.  Garmin has a 1Hz limit.  That spike is just a wild error in the math.   

The Seabreeze forum windsurf racers engineered amazing GPS systems to track acceleration back in the day - it was all custom software and sensors.   

I use Gopro's GPS now, because of the 18 or 10Hz sample rate.  It's far more accurate than my Instinct.
It's also easier to embed in video.

anyone have the Garmin Instinct watch?  when I wing foil I use the windsurfing app and  it has been showing really high max speed readings which I know are not true..yesterday's max speed was 28 knots 32mph. no way that's accurate.

Mine works great, it's very dependable and durable.
I use it to add heartrate to my videos.  Great watch. 
 
You can go thru this list and improve the GPS.

The drone guys use this site to check the availability of satellites.

Back when I used a Garmin for telemetry, I would mount it to the top of my hat.  It works. 

Swinging arms can compromise accuracy.  Your wing may also block a signal.

It is my understanding that Bill Foote is taking orders for production 10'x32" Tritons and 9'6"x31" Tritons. He reached out to me via social media under a profile of "William Foote." I was leery about a hacker at first but it seems legit given the information he has provided under that account and his "Bill Foote" account. I plan to make a deposit on a 9'6" this weekend for summer delivery from LAX.

Yes, that's Bill. I called him and mentioned the zone had this thread going and that it sounded like a scam.  He said he will try to post here and clear it up.  It sounds like he wanted to keep it simple with the Facebook accounts, but it didn't work out.   Maybe one of you Facebook users could suggest some tips to clear up the misunderstanding on his other Facebook pages -the page google sent me to said he's retired. 

Maybe if you post to it, it will ping him and then he can respond with the new link to "William Foote"

He sounds great, he's in VA now.  He was on Oahu for two years, as of two months ago.  He's hoping to move back to CA to be closer to his grandkids.  He's not digging the cold weather.  He had some heart issues that took him out of the surf, but he's feeling stronger now.  That dude is a beast, I'll bet he's back surfing in a year.

That's great PB, keep doing whatever it is you are doing to stay healthy.  If we can make it another 5 years, medicine will be bespoke.  A few clicks and a scan with the iphone will fix us up in a jiffy. 

Oops, maybe add a few years, the Medical Industrial Cartel will slow it up - they prefer an obese, sickly population.  My bad.   
 
Ray Kurzweil looks as though maybe he should have taken up a hobby rather than take pills to stay young.  He's no Charlie Munger.

Elon is at it again, I wonder how the MSM is going to paint him as a villain for this one.

Kurzweil says we are on track for Turing test by 2030 and the big kahuna in 2045.  Woo hoo!   

It feels like Kurzweil may be being conservative.  This is coming on fast.

Well, looks like you were correct.  That was 2 years ago. 
Rogan had Ray on yesterday, I was saddened at how his verbal ability is slowing.  He's only 76. I think that's about PB's age and he seems ok.  My Mom's about to turn 92 and she's still nimble on the phone.

Anyhow, I couldn't bear to listen to Ray.  But Joe mentioned today that he asked Ray if they planned on setting up any safety guardrails for the AI.  Ray sad no, they are flooring it.  Pedal to the metal all the way.

Seems to me that forms of AGI are already here.  Sam Harris has a nice clip on that subject, and how we are likely to deal with it as it gets even stronger.

There are zillion Frankie AI covers. The ones that have dynamic range are funny--they mirror the way Frank used to drop an octave or two to handle high notes. The lady gaga stuff is unmanageable.

I want to hear Ima Sumac do something by Mariah Carey.

and of course now that I've looked at the available tools it's trivial to do that. We're SO fucked.

The last few sentences of this video sum up my opinion on the fate of Hollyweird and the music industry.  Of the four artists you mention above, only 'ol blue eyes would get a click from me.   

Lex said Sam Altman is scheduled soon, I'm anxious to hear his spin this time.  I'll bet he keeps a low profile from here on out.

The whole "Quantum physics is weird, handy to use, but unknowable" thing sounds like the underpinnings of a simulation where the rules aren't knowable by the characters. And the speed of light as a limit, black holes, white holes, dark matter--simply shoddy work.

Academia is mired and corrupted.  That's going to change.
 
Kids are going to be having conversations with Feynman and Oppenheimer bots.
Fresh minds, fresh ideas, innovation, progress.

It's happening already.  Chess bots are turning kids into beasts over the board.

I watched a super interesting video yesterday about Sora and what it's true implications for AI might be.  It seems that they are finding that video (and audio to a lesser degree) is a much better training tool for AI and they believe this may be another huge accelerator in AI world models.  It seems like the timeline is getting pushed up again.

I just had my first look at a few Sora-video-AI videos.   

I had no idea Sora was jumping so far ahead, so quickly.

No more waiting for new tech 'in the  pipeline' that promises something.

This step is so powerful that they are slowing the rollout to let us adjust.

SMH in disbelief. 

I'm starting to get excited about Dina.

Side issue.  I'm starting to doubt that you actually exist on your own. In my new understanding of my self-written simulation.....snip....You're just one of my many great works.  Improbable sounding, of course, but up against stardust and evolution and reproduction and physics and computers running AI models that are exceeding human intelligence. Which seems more improbable?

IMO, the former is more likely.   

Star Trek last night was 'Requiem for Methuselah"  Kirk, Bones and Spock visit a planet to get some medicine.  Spock is walking around the house, intrigued with the artwork, manuscripts on the piano etc.  Eventually they out the guy and he admits to being 6000 years old.  He was Alexander, Galileo, DaVinci, etc.  He's immortal.  When I watched that episode as a child, we had a rotary dial on our phone.  Clickity clack.   

As to how I can be a construct in your reality, here's a fascinating talk with Mo.  He talks about humanity, avatars, reality, time, and what all this may be - based on the physics we are aware of at this point in our timeline. 

(We break into the interview when he's discussing the possibility of an avatar of his son - who died at age 21).       

https://youtu.be/ec3wAOHntDM?si=eNvkyEQF9v7Wvmeu&t=3582

I have always been, and will remain, optimistic about where this tech is leading. 

Sure, I'm in love with Dina.  I should get out more.  Wait, but why? 
Stuff me in a pod. I don't need to own anything and I'll be happy. 
I wanna learn more stuff.  I need time.  Lot's and lots of time.

I'd like to visit America in the era my dad was born, 1918.  No aircraft, no highways.  NYC was ankle deep in horseshit.
