Abstract

The invention relates to an X-ray pulsar navigation ground test system, which comprises a signal control sub-system, an orbital data generation sub-system, a navigation database sub-system, a pulse contour extraction sub-system, a navigation parameter estimation sub-system, a large-scale dynamic effect sub-system, an X-ray pulsar signal simulation sub-system, a detector sub-system and a navigation demonstration sub-system, wherein the orbital data generation sub-system comprises a Walker constellation satellite orbit module, a lunar exploration module and a Mars exploration orbit module; the large-scale dynamic effect sub-system comprises a large-scale space effect simulation module and an in-orbit dynamic effect simulation module; and the X-ray pulsar signal simulation sub-system comprises an X-ray generator and a vacuum channel. By realistically simulating the radiation characteristics of pulsar X-ray photon signals in a large-scale dynamic environment, the performance of a pulsar navigation probe is subjected to a closed loop test, the pulsar navigation algorithm is examined, and the feasibility of the scheme design of the pulsar navigation system is verified.

Description

technical field [0001] The invention belongs to the technical field of autonomous navigation of X-ray pulsar spacecraft, and relates to an X-ray pulsar navigation ground test system. Background technique [0002] The radiation of pulsars in the X-ray frequency band is mainly concentrated at 0.1~15keV, but due to the strong absorption of X-rays in this frequency band in the earth's atmosphere, the X-ray signals radiated by pulsars cannot be received on the ground; therefore, it is necessary to break through pulsars Key technologies such as analog source, large-scale space-time reference, high-stability pulse waveform modulation and time retention, etc., build a ground distributed, full-channel, semi-physical, closed-loop test and verification system to meet the ground test verification and program design of key technologies of the pulsar navigation system The demand for quantitative demonstration of feasibility lays the foundation for the space flight test of pulsar navigatio...
