| Abstract: | Several significant applications of pulsar timing have been introduced.The brief definition of pulsar time scale is proposed.The ensemble pulsar time integrated by four millisecond pulsars has been produced based on the observational data observed by Parkes Observatory in Australia.Its stability is compared with atomic time.Four factors influencing the ensemble pulsar time and its effects on timing precision are discussed. |
| Keywords: | astrometry time pulsars general |
