Usually, satellite orbits are approximated with smooth functions, currently, their accuracy is about 2-3 cm. Unlike ephemerides satellite clock biases are not approximated with any function, also clock series are being processed not as a continuous time series but as daily fragments, which leads to jumps at 00:00 UTC.
