Carrier rocket task planning method for rapid spacecraft rendezvous

Abstract

The invention discloses a carrier rocket task planning method for rapid spacecraft rendezvous, and relates to the technical field of aerospace. The method comprises the following steps of S1, determining a longitude adjustment value of geographic longitudes of ascending nodes of a tracking spacecraft according to a propellant reserved by a carrier rocket; S2, calculating a geographic longitude interval in which the tracking spacecraft can rendezvous with a target spacecraft after the tracking spacecraft enters an orbit according to the longitude adjustment value and a plurality of selectable launching sites of the carrier rocket; S3, determining the geographic longitudes of the theoretical ascending nodes and a selected launching site of the carrier rocket according to the geographic longitude interval and the geographic longitudes of the ascending nodes of all circles of the target spacecraft orbiting the earth in one day; S4, calculating theoretical launching time according to the selected launching site and the geographic longitudes of the theoretical ascending nodes; and S5, launching the carrier rocket at the selected launching site and the theoretical launching time to enablethe tracking spacecraft to enter a rendezvous orbit. According to the carrier rocket task planning method, at least one launching moment can be ensured in one day, so that the tracking spacecraft canrendezvous with the target spacecraft rapidly.

Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to a launch vehicle mission planning method for rapid rendezvous of spacecraft. Background technique [0002] With the development of aerospace technology, the rendezvous technology between tracking spacecraft and target spacecraft has become relatively mature. At present, the demand for space emergency rescue and cargo transportation tasks in emergency situations is becoming more and more urgent. Therefore, the construction of my country's space emergency system is of vital significance to my country's promotion of the construction of space stations, the protection of the safety of astronauts, and the steady advancement of my country's space exploration and the construction of an aerospace power. [0003] In related technologies, although the traditional rendezvous mode can realize the rendezvous and docking of the tracking spacecraft and the target spacecraft, it has relativel...
