Launch vehicle mission planning method for rapid rendezvous of spacecraft

Abstract

The invention discloses a carrier rocket mission planning method for fast rendezvous of spacecraft, relates to the field of aerospace technology, and includes the following steps: step S1, according to the propellant reserved by the carrier rocket, determining the longitude adjustment of the geographic longitude of the ascending node of the tracking spacecraft value; step S2, according to the longitude adjustment value and multiple optional launch sites of the launch vehicle, calculate the geographic longitude interval that the tracking spacecraft can rendezvous with the target spacecraft after entering orbit; step S3, according to the geographic longitude interval and the target spacecraft orbit Carry out the geographic longitude of the ascending node of all circles of the earth in one day, determine the geographic longitude of the theoretical ascending node and the selected launch site of the launch vehicle; step S4, calculate the theoretical launch time according to the selected launch site and the geographic longitude of the theoretical ascending node; step S5, with Select the launch site and the theoretical launch time to launch the carrier rocket, so that the tracking spacecraft enters the rendezvous orbit. The invention can ensure that there is at least one launching moment in a day, so that the tracking spacecraft can quickly rendezvous with the target spacecraft.

Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to a mission planning method for a launch vehicle for rapid rendezvous of spacecraft. Background technique [0002] With the development of aerospace technology, the rendezvous technology between the tracking spacecraft and the target spacecraft has become relatively mature. At present, the need for space emergency rescue and cargo transportation in emergency situations is becoming more and more urgent. Therefore, the construction of my country's space emergency system is of vital significance for my country to promote the construction of the space station, ensure the safety of astronauts' lives, and steadily promote my country's space exploration and the construction of a space power. [0003] In the related art, although the traditional rendezvous mode can realize the rendezvous and docking of the tracking spacecraft and the target spacecraft, it has high requirements on the l...
