Rich Felker@khm @aburka @gleick Correct me if I'm wrong, but my understanding of a Kessler Syndrome situation is that GPS would fail gradually via inability to replace, not suddenly. So my naive view is that we'd have time to deploy replacements that don't depend on access to space. Something GPS-like should be possible with constellations of "weather balloons" tracking their precise positions relative to earth optically.
