The re- sults from the two different types of experiments show that the VLBI is more stable than GPS but is slightly noisier than two new two-way techniques (TW(DPN), ETS8(TCE)), and VLBI can measure the correct time difference as same as ETS8(TCE).All VLBI data products are archived in IVS Data Centers and are publicly available.Conference ContributionOpenAccess
