  Detecting the X-ray radialization of pulsars and obtaining the photons' time
of arrival are the foundation steps in autonomous navigation via X-ray pulsar
measurement. The precision of a pulse' s time of arrival is mainly decided by
the precision of photon arrival time. In this work, a silicon drift detector is
used to measure photon energy and arrival time. The measurement system consists
of a signal detector, a processing unit, a signal acquisition unit, and a data
receiving unit. This system acquires the energy resolution and arrival time
information of photons. In particular, when background noise with different
energies disturbs epoch folding, the system can acquire a high signal-to-noise
ratio pulse profile. Ground test results show that this system can be applied
in autonomous navigation using X-ray pulsar measurement as payload.
