Question: This seemed like a couple of mistakes, but I'm not a technology expert: First of all, if the aliens are interfering with Earth's satellites, how are cellphones able to work [so well]? Secondly, how is Dave able to triangulate Connie's position? He sticks some kind of device on his roof, and presumably uses a satellite. Regardless of the satellite problem, I thought triangulation (as the name implies) needed at least three points for determining location.

Answer: Cell phones do not use satellites, they use towers on the ground in each area and land lines to link each area. So as long as the towers and lan lines are still there the cell phones will work. He triangulates her position using a signal from the cell towers on earth, and you do need 3 points, but those points are just 3 towers on earth, no satellites involved.
