I'm not convinced that the ship that crashed was a good design. When GPS fails, it seems logical to switch to dead reckoning only if there is no human available to take over. If you've got a human crew available, it seems like a better choice to just stop the ship and let them handle it.
- lnguyen 17y agoThe design issue in this case is not making it blatantly and unavoidably obvious that the GPS had failed. The dead reckoning system should probably also give an error range instead of keeping any appearance of the same "pinpoint" accuracy.
- ars 17y agoThe system was self steering (i.e. driving the ship) - there was no one to give an error range to. No one was watching it because it normally works so well that there is no reason to double check it. An error indicator is no help if no one goes to look at it.
