VLBI has been used for high precision EOP measurements since 1980. The typical formal error for current routine monitoring of polar motion is ~80 µas. A program for continuous EOP observations using VLBI is being incrementally implemented. There are unexplained differences between EOP values derived from simultaneously observing networks.
