Relative navigation using pulsar signals

摘要：

Pulsar navigation has shown its great potentiality in autonomous navigation for orbit satellite and deep space spacecraft. Relative navigation using pulsar signal has shown its benefit in recent years, and higher performance has achieved in some studies. The proposed method in this paper uses X-ray and radio spectrum of pulsars to implement the relative navigation and the DSN range measurement are employed to enhance the performance. We discusses and models the main influence factors for the performance such as high-order time transfer of pulsar signal, ionosphere transfer characteristic and range observation of DSN. Extended Kalman Filter is used to literately update the estimation of navigation parameters. The experiments are designed to explain the feasibility and performance.
