| Abstract: | Three kinds of X-ray pulsar attitude determination methods were presented in this paper.First,the basic principle of this method was introduced,and their advantages were compared with existing methods.Then,the vertical pair vector relative attitude determination methods were tested using simulated data.Focusing on the attitude determination accuracy,the impact of the time delay measurement error,the number of observable pulsars and the pulse's ephemeris error were studied,and some useful conclusions were given finally. |
