Abstract

The requirements for GPS time transfer accuracy are more drtMnding than ever before. The Operatio~l Cont~d Segment kcrs respond& providing a u m s k t d y accurate signal to the user community. lhis paper presents a sumof GPS Tinu Thznsfer performance for 1996 and offos severcrl theories for the continued improved Pcrfarmance. Rrfrned techniques in the arms of MCS sateUite c W estimation and mnifor station clack performance assessment are Wo arms with significant impact to GPS time. As histoticd perspective, 1995 time trarrrfer performance is compared to the current gear's data.
