We present the timing system and the performances of the three payloads onboard the Insight-Hard X-ray Modulation Telescope (Insight-HXMT). Insight-HXMT carries three main payloads onboard: the High Energy X-ray telescope (HE, 20-250 keV), the Medium Energy X-ray telescope (ME, 5-30 keV) and the low Energy X-ray telescope (LE, 1-10 keV). We have reported the results of time-cumulative pulse profiles and period evolution using long-term monitoring data of the Crab pulsar. To compare the measurement of the time of arrivals (ToAs) on Crab pulsar, we use the quasi-simultaneous Crab observation with the X-ray Timing Instrument (XTI) on-board the Neutron star Interior Composition Explorer (NICER). The systematic errors of the timing system are determined to be 12.1 {mu}s, 8.6 {mu}s, and 15.8 {mu}s for HE, ME and LE respectively. The timing offsets are delayed with respect to NICER about 24.7 {mu}s, 10.1 {mu}s and 864.7 {mu}s for HE, ME and LE respectively.
We present the calibration of the Insight-Hard X-ray Modulation Telescope (Insight-HXMT) X-ray satellite, which can be used to perform timing and spectral studies of bright X-ray sources. Insight-HXMT carries three main payloads onboard: the High Ene
As Chinas first X-ray astronomical satellite, the Hard X-ray Modulation Telescope (HXMT), which was dubbed as Insight-HXMT after the launch on June 15, 2017, is a wide-band (1-250 keV) slat-collimator-based X-ray astronomy satellite with the capabili
The hard X-ray detector (HXD) on board the X-ray satellite Suzaku is designed to have a good timing capability with a 61 $mu$s time resolution. In addition to detailed descriptions of the HXD timing system, results of in-orbit timing calibration and
The Nuclear Spectroscopic Telescope Array (NuSTAR) mission is the first focusing X-ray telescope in the hard X-ray (3-79 keV) band. Among the phenomena that can be studied in this energy band, some require high time resolution and stability: rotation
The Hard X-ray Imager (HXI) onboard Hitomi (ASTRO-H) is an imaging spectrometer covering hard X-ray energies of 5-80 keV. Combined with the hard X-ray telescope, it enables imaging spectroscopy with an angular resolution of $1^prime.7$ half-power dia
