For instance Apollo 10's S-IC was 30.188 deg N, 74.207 deg W while Apollo 11's was 30.212N, 74.038W. I don't know how big an area a location to that accuracy would cover. Those are pretty accurate locations. At the equator, 0.001 degree is about 100 meters, and it is less than that at those locations - if they are rounded properly and not converted from less-accurate minutes and seconds. And if they're actually accurate. i.e. we don't know the CEP. And that could make a difference. -- Greg D.

Well, they are certainly precise. We might assume accuracy. The timelords over in comp.protocols.time.ntp often point-out the distinction between precision and accuracy when discussing time and I suspect the same applies for location. rick jones -- A: Because it fouls the order in which people normally read text.

Quoting from the bottom "Theoretical impacts compiled from Saturn V launch vehicle flight evaluation reports, and Apollo/Saturn V postflight trajectory reports." This is what they calculated theoretically. |
