pulsars: general  techniques: miscellaneous  Astrophysics -  Instrumentation and Methods for Astrophysics  Abstract: In this work, we report the in-orbit demonstration of X-ray pulsar navigation with Insight-Hard X-ray Modulation Telescope (Insight-HXMT) Satellite, which was launched on 2017 June 15. The new pulsar navigation method Significance Enhancement of Pulse-profile with Orbit-dynamics is adopted to determine the orbit with observations of only one pulsar. In this test, the Crab pulsar is chosen and observed by Insight-HXMT from 2017 August 31 to September 5. Using the five-day long observation data, the orbit of Insight-HXMT is determined successfully with the three telescopes onboard: High Energy X-ray Telescope, Medium Energy X-ray Telescope, and Low Energy X-ray Telescope, respectively. By combining all the data, the position and velocity of the Insight-HXMT are pinpointed to within 10 km (3ҩ and 10 m s-1 (3ҩ, respectively.

In order to match the intersectant targets' tab when these objects separate  a kind of method that makes use of fuzzy multi-parameter to match targets is proposed. Multi-parameters include the forecasted position after targets separate  target speed  target size and geometry shape  and different parameter corresponds to different influence coefficient  evaluate the integrated matching coefficient that every observation target corresponds to forecasted target  and the corresponding relationship that matching coefficient is the biggest is the best matching result. In order to locate the position and speed of forecasted target  a new method of track forecast is proposed  firstly  Hough transform is used to the object's track before objects intersect  by this  the object's positions that the warp between forecasted location and observation location is large enough is eliminated  then least square method is used for track forecast by the remainder valid positions  and get hold of the forecasted position when objects separate. The experiment results show: when tracking the bulky objects which intersect and separate  the right identification probability of traditional least square method is 87.5%  and the right identification probability of fuzzy match by multi-parameters can attain 96%  the reliability improves in evidence.
