Abstract The longterm variations of a variety of GPS receivers’ DCB were analyzed based on the DCB published by the Center for Orbit Determination in Europe during 2001—2009. The results show that there are periodic behaviors in the timeseries of the change receivers’ DCB, among then the monthly and yearly periods are the most predominant. In addition, certain fluctuations underlying the longterm behaviors in GPS receivers’ DCB can also be found, and some of the GPS receivers may suffer the deterioration of DCB stability, or even somewhat deviation.
