Call it 1 part in > 2000! This is not consistent with the data on the accuracy of modern inertial navigation systems which were discussed on this list approx two years ago. The discussion had ballistic missiles in the title, but it was mostly about inertial navigation. Some data from manufacturer advertisements were posted. They are worse by orders of magnitude, if I remember correctly. Perhaps we had a regress in this technology since the times of Nautilus:-) Alex.
