But I don’t wanna.

It’s not going to have location data. GPS doesn’t work under even very shallow water.
Geodad@lemmy.world 3 weeks ago
Nobody said GPS (except for you). Location data does not mean GPS.

Ok, so tell me how you are going to get a location fix underwater, in the dark, with no landmarks to orient yourself, in constantly shifting currents?

Like on every ship ! by looking at the stars

You use your starting point as a baseline and keep track of the movement of the craft.

Yes and they use SINS, now this probably didn’t have an expensive SINS setup but they did have communication with the surface that was tracking them on sonar. They did have location data.

And what do you think that polling rate was to fill up a 512 GB SD card? It’s all speculation but this isn’t a supper collider, we shouldn’t need sub second polling of a vehicle that can only move 5.6 km/h.

And even if you sampled at 10 sps, and did 50 sensors at 10b, you would still only be looking 5000bps or 5.8x10^-7^ GBps, meaning that it would take roughly 26 years to fill up a 512GB SD card.
While I don’t know for how long the sub had been submerged, I doubt it was close to a quarter of a century. If that was the case, I believe that we would have been talking about that as well. Even if it was 500 sensors, at 100sps at 12b we’d be looking at 79days.
IMHO there’s only a few things a 512GB SD card would be used for. And I hope it was music, because I don’t think we should watch the final moments of these people’s lives.
