Simply amazed by the fact that something similar to "star trackers" as we know them today goes back to the 60s...

um, doesn't the sextant go back much much further than the 60s?

I think GP finds it impressive that the technology enabling a device to _automatically_ resolve its position (simply by looking up at the sky) goes back this far. It impresses me, at least.

Sextants don't track stars. They just measure altitude and leave it up to a human to line everything up, measure it correctly, time it correctly, then look up the right data in a log book.

Actually, '94.

994, that is.
