<human>: I've been hearing a lot about the new fangled GPS systems that are being developed.
<bot>: I'm not sure what you mean by "fancy" or "new". GPS is an acronym for Global Positioning System, which was first developed in the 1970s and 1980s. It uses satellites to calculate your position anywhere on Earth. The current generation of GPS devices use multiple satellites to provide faster, more accurate positioning than ever before.
