“…However, its positioning accuracy is only to hundreds of metres, which limits its application in the orbital spacecraft navigation area. To increase the accuracy, several methods can be adopted, such as refining the phase prediction model (Deng et al, 2012; Zhang et al, 2016; Wang and Zhang, 2017), improving time measurement of pulsar signals (Ning et al, 2018; Huang et al, 2009; Sheikh et al, 2007) or increasing additional information (Liu et al, 2010; Qiao et al, 2009; Wang et al, 2017; Liu et al, 2015; Ning et al, 2017). Among these methods, increasing additional information is an interesting candidate.…”

X-ray Pulsar Navigation (XPNAV) uses the Time Difference of Arrival (TDOA) of the pulsar signal between the spacecraft and Solar System Barycentre (SSB) to determine position. In this paper, a novel method to improve the performance of XPNAV via exploiting the pulsar position vector is proposed. First, the field of view of the collimator is utilised to find the pulsar orientation direction. Then, a searching strategy based on the modified Powell method under given coordinate frames is proposed. We also mathematically prove the existence of the extreme value of the searching strategy. Subsequently, an observation model based on the pulsar radiation vector is presented and applied to formulate the observation function together with pulsar time transfer function. Finally, an Adaptive Divided Difference Filter (ADDF) algorithm is introduced to iteratively estimate the position and velocity of the spacecraft. Numerical simulations show that the vector searching method is feasible and the pulsar radiation direction can improve the navigation performance by 75%. The simulation results also show that the ADDF performs better than Unscented Kalman Filtering (UKF) and DDF in position estimation.

“…This leads to high noise in velocimetry. To reduce the error, the solar Doppler difference navigation method was developed in 2015 [21]. In this navigation method, the Doppler difference velocity is obtained by comparing the direct solar spectrum with the reflected spectrum from Mars.…”

“…These works show that an accuracy of only several hundred meters can be obtained using the state-of-the-art technology. Some improved methods, which employ additional resources such as the Sun or stars, have been proposed (Ray et al, 2002;Liu et al, 2015). These methods require a subsystem to deal with the additional inputs, which increases the complexity and burden of the navigation system.…”

X-ray pulsars offer stable, periodic X-ray pulse sequences that can be used in spacecraft positioning systems. A method using X-ray pulsars to determine the initial orbit of a satellite is presented in this paper. This method suggests only one detector to be equipped on the satellite and assumes that the detector observes three pulsars in turn. To improve the performance, the use of incremental phase in one observation duration is proposed, and the incremental phase is combined with the time difference of arrival (TDOA). Then, a weighted least squares (WLS) algorithm is formulated to calculate the initial orbit. Numerical simulations are performed to assess the proposed orbit determination method.
