摘要：

Considering　the　deficiency　of　GPS　common-view　method　in　terms　of　comparison　precision,　two　way　satellite　time　and　frequency　transfer　technology(TWSTFT)was　adopted.　The　comparison　precision　of　TWSTFT　could　approximately　reach　0.　3ns.　According　to　the　theory,　the　satellite　ground　station　was　constructed　to　complete　time　and　frequency　transfer.　When　the　data　was　primarily　processed,　the　coherence　of　the　final　computation　results　with　the　Physikalisch　Technische　Bundesanstalt(PTB)　data　indicated　that　the　system　was　reliable　with　the　influence　of　path　delay.　The　system　for　time　and　frequency　transfer　has　been　successfully　applied　to　timekeeping　and　time　service　of　National　Institute　Metrology(NIM).
