LOCATACORPORATION TechnologyBrief 1.LocataTechnologyOverview Locatahasinventedanew,completelyautonomouspositioningtechnology.Itcreatesterrestrial networksthatfunctionasa“localground-basedreplica”ofGPS-stylepositioning.Locataisnot designedtoreplaceGPS;itisalocalextensionandexpansionofGPS.ItworkswithGPS,butcanalso operateindependentlywhenGPSisnotrobustorcompletelyunavailable.Insteadoforbitingsatellites, Locatautilizesanetworkofsmall,ground-basedtransmittersthatblanketachosenareawithstrong radio-positioningsignals.Becauseitisterrestriallybasedandprovidespowerfulsignals,Locatacan workinanyinternalorexternalenvironment. NotonlydoesLocataintegrateseamlesslywithGPS,itsimultaneouslyeliminatesmanyGPSdeficiencies.
