Shameless liesSPARC cannot replace GPS or what it does, even the company isn't putting forward that claim. Anyone claiming that SPARC can replace GPS does not understand what GPS does or what SPARC does or how either of them work. Someone making this claim is either lying or unable to read and think critically. Don't take tech advice from someone who can't even change the time on a mechanical clock and is scared of having a flush toilet in their house. Utter drivel.
