| Oct 28, 2015 at 1:23 | comment | added | CuriousOne | IMHO, that would be more than enough, but I would say that it's probably just a backup system to much finer resolution readily achieved by the drive mechanism. Don't get me wrong, but the Hyperloop, so far, strikes me still as the product of people who like to sing in the shower but have very little (if any) experience with the design of large systems. This "problem" and its ad-hoc solution in the specification (a document which is NOT supposed to have a fixed solution to the demands that it makes) is one of those little hints that are giving this away. | |
| Oct 28, 2015 at 1:19 | comment | added | michaelsnowden | @CuriousOne The updated hyperloop tube spec says "Every 100 feet, a 2-inch wide reflective circumferential stripe will be applied to the inner circumference of the tube." under the navigation system. Do you think this will suffice for determining the velocity? | |
| Oct 28, 2015 at 1:11 | comment | added | CuriousOne | The linear induction system can and almost inevitably will have periodic structures which will allow you to derive very precise location information from the track. I wouldn't worry about this "problem", at all, the folks who will design that part of the system will take care of that for you. | |
