Other than global positioning system, what else does GPS stand for?

Answer 1

It depends on the context - for example, in a fabric store it could mean "green polyester strands".

An alternative question in the context of GIS and geospatial technology would be, "What is an alternative and more inclusive acronym for GPS?"

Which would be GNSS, or Global Navigation Satellite System. GPS is the satellite constellation created by the United States - so GNSS would include GPS (United States), GLONASS (Russia), Galileo (European Union), Beidou (China), QZSS (Japan) and so on.
