Aircraft navigation method based on earth high orbit-earth and moon libration point heterogeneous constellations

Abstract

The invention provides an aircraft navigation method based on earth high orbit-earth and moon libration point heterogeneous constellations. The aircraft navigation method comprises the following steps of firstly, utilizing a pulsar detector and intersatellite ranging observing equipment to obtain the corresponding pulsar and intersatellite ranging observing amount, so as to realize the autonomous navigation of the earth high orbit-earth and moon libration point heterogeneous constellations; after the heterogeneous constellation realizes the autonomous navigation, arranging the intersatellite ranging observing equipment on the aircraft, and observing the heterogeneous constellations to obtain the corresponding position information; using a corresponding navigation method to determine the self position and speed, so as to realize the autonomous navigation of the aircraft. Compared with the navigation method based on a ground measuring and controlling system, the aircraft navigation method based on the heterogeneous constellations has the characteristics that the communication delay is little, the signal attenuation is little, the positioning accuracy is high, and the navigation efficiency is high.

Description

technical field [0001] The invention relates to a navigation method for a spacecraft, in particular to a navigation method for an Earth-Moon space spacecraft based on a heterogeneous constellation of Earth's high orbit-Earth-Moon translation point. Background technique [0002] Navigation and positioning is one of the key technologies in deep space exploration missions. At present, the navigation information of the spacecraft is mostly provided by the ground measurement and control system. However, for deep space spacecraft, the large communication delay makes it impossible to obtain navigation information in real time; the great weakening of the signal also reduces the positioning accuracy of deep space spacecraft. In order to reduce operating costs and improve the autonomy and survivability of spacecraft, it is necessary to realize autonomous navigation of deep space spacecraft.

[0003] Among the existing invention methods, the patent application No. 201310377058.3 proposes a beacon layout and autonomous navigation method for the deep space autonomous navigation system. This method only explains how the beacons of the deep space autonomous navigation system are spatially configured. The autonomous navigation method of the beacon and how to apply it are not specified; the patent application number 201010144459.0 proposes a multi-information fusion formation spacecraft autonomous relative navigation method, which uses pulsars to provide absolute position information for the formation spacecraft. The pulse arrival time is used as an observation quantity, and its observation quantity is an absolute observation, with low positioning accuracy and large positioning error. Another Chinese patent 201510824899.3 discloses a Lagrangian navigation constellation and its construction method that seamlessly covers the lunar space. This constellation only explains the configuration of the navigation constellation, but does not explain how the navigation constellation itself realizes navigation
