If you visit http://www.navcen.uscg.gov/pubs/gps/sigspec/gpssps1.pdf you can get the formal definition of the GPS signal. If you go to page 32, you will find a table that describes the meaning of the various parameters. The only unit of length mentioned is "meters". ELsewhere in the document there are other references to lengths, all of which are in "meters". In addition, the document references the WGS-84 grid - also a metric creation.
