Spared no expense…

Kinda seems like it was the right call if it survived an implosion

Yeah, but 512 GB? That’s gotta be overwriting some data. The amount of data generated by sensors is massive.

What sensors do you think this was recording?
Show threadGeodadOct 19
Depth, pressure, location, etc.

It’s not going to have location data. GPS doesn’t work under even very shallow water.

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

U mean starfish?

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

Just because you set the sub to a set knot speed, doesn’t mean it’ll actually cover that distance in that time. There are ton of currents going in all different directions.

Dead reckoning. Usually hit or miss on the surface. Probably worse under the water.

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.
