Actually, if Earth would disappear with all its mass, GPS would
get unusable, as the satellites would continue out of their
tracks due to the lack of gravity pull.

Yeah, but they'd work longer than a pressure altimeter so I think we should
still adopt GPS altimeters in case this ever actually happens.

Good idea! It's always smart to be prepared. I always carry a
towel with me whenever I fly. Just in case.
