   @khm @aburka @gleick You can do surveying & construction without GPS. Maybe minor cost increase but no harm/danger. You can do farming without GPS, but it breaks some of the current large-scale automation. It can be replaced with locally operated triangulation or legacy LORAN-like. I'm not qualified to speak on the air and sea traffic but making them more expensive sounds good for climate...

     @khm @aburka @gleick For populated areas, non-GPS-based positioning based on wifi, etc. probably already outperforms it anyway (but is fragile, vulnerable to spoofing, etc.)

     @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.

     @dalias @khm @gleick you can get a debris cascade, so it would be gradually and then all at once, exactly the type of problem humans are calibrated to avoid solving until it's too late :/
