Sometimes we need to give awesome tools to creative people and see what they come up with, even when we don't understand the implications ourselves.

I think millimeter accurate GPS is one of those tools. It has the power to enable so many things. Things we cannot imagine without using the tool itself.

40 cm vs 1 mm is the difference between landing a quadcopter smoothly or crashing it into the ground.

20 cm vs 1 mm is the difference between a robot navigating through a door or crashing into the wall.

20 cm vs 1 mm is the difference between mowing the lawn or cutting through your flower bed.

Unfortunately it doesn't look like we'll be getting millimeter accurate GPS anytime soon. The Genesis satellite might be a prerequisite though.

The government artificially limits civilian gps resolution. Millimeter gps would be a boon for hellfire R9X type explosive free ballistics.

This hasn’t been true for 24 years. Selective Availability was discontinued in May of 2000.
