I expect starlink to eat that industry shortly. Not sure how they'll make the strategic steps though. Mandatory location data for cell phones to talk with star-link? Wait for whatever satellite septentrio uses to EOL and offer a deal to use star-link instead?
Also possible use cases: Drones, Drone attacks on individuals with smartwatches, tracking of dissidents, these days you have to think about all possible angles.
I imagine a system where several devices broadcast their coordinates to each other, and this way each device knows how far it is from a device and approximates its location based on the distance and coordinate of the other device, then matches it with its own GPS to narrow its coordinate even further.
Just one more piece of the behavior recognition and total sensor fusion puzzle. This can also be used to train passive RF based sensing techniques to be more accurate.
Even with the stationary requirement, this is pretty neat.
One could imagine cheap turn-key devices that self locate and provide an accurate beacon for real time triangulation.

Not cheap.
Theres also services like this: https://www.septentrio.com/en/learn-more/insights/gnss-corre... that offer correction information.

> centimetre-level precision over four hours with a stationary setup
Ok, so does this really mean the smartwatch should not move for four hours?
Yes.
I mean it does demonstrate you can do it with something as small as a smartwatch
Cheap positioning for construction projects.
Precision is not accuracy. I wouldn’t use this on a construction project without first setting a control point.
while researching links to back up me calling this a nothing burger, I found this: https://m.youtube.com/watch?v=twqqak3XVuY which upgrades this to Puff Piece.
it gets worse- the overseeing professor mentioned here, and in the video, is the author of the paper linked in the description- from 2018. (https://link.springer.com/article/10.1007/s00190-018-1192-5)
See: https://www.u-blox.com/en/technologies/high-precision-positi... for information thats not one guy stroking his... ego.
Also, PPP-RTK is another keyword.
How can this support the panopticon of public safety?
