A new explorer mission for soft X-ray timing - Observation of the Crab pulsar

We discusse the current X-ray observation results of Crab pulsar obtained with the Time-resolved soft X-ray spectrometer, X-ray pulsar navigation 1 satellite launched on Nov. 10, 2016, summarize the 162 observations of the TSXS from MJD 57709 to MJD 57872, and introduce the propositional method of data reduction. We compare these observation results in the 0.5-9.0 keV energy band with the radio timing parameters by folding the profiles with radio timing ephemerides derived from Jodrell Bank and estimating the phase delay results. The statistical error of post fit time correction is 55.94 μs (root mean square). These achievements verify the effectiveness of the Time-resolved soft X-ray spectrometer and laid the foundation of the future work of the X-ray pulsar navigation 1 mission.
