Problems solved by technology

The existing technical means have the following problems: ① Manned spacecraft needs to carry out multiple on-orbit tests during different flight stages, such as platform tests at the initial stage of orbiting, tests before each rendezvous and docking mission, regular The frequency of on-orbit testing is much higher than that of satellites, and the existing satellite on-orbit testing methods are difficult to adapt to and meet the needs of manned spacecraft to carry out multiple on-orbit tests; There are many mission modes and types. If you need to carry out multiple rendezvous and docking missions with manned spacecraft and cargo spacecraft, you need to carry out multiple propulsion and supplementary missions with cargo spacecraft, and you need to support ast

Abstract

The invention relates to an in-orbit test method for a low earth orbit long-life manned spacecraft. The in-orbit test method for the low earth orbit long-life manned spacecraft comprises the followingsteps of a, in-orbit test carried out after the spacecraft goes into a light orbit; b, in-orbit test carried out before the spacecraft develops a docking and adding mission; and c, in-orbit test carried out during the autonomous flight period of the spacecraft. The in-orbit test method for the low earth orbit long-life manned spacecraft can make targeted test projects and carry out multiple in-orbit tests for different flight stages and the executions of different missions.

Description

technical field [0001] The invention relates to the field of on-orbit management of manned spacecraft, in particular to an on-orbit test method for low-orbit long-life manned spacecraft. Background technique [0002] Manned spacecraft belongs to the category of manned space vehicles that fly autonomously in orbit for a long time and are attended by people in the short or medium term. After the manned spacecraft enters the orbit and completes the initial state setting of the platform, it is necessary to carry out a special on-orbit test on the platform to evaluate the working state of the platform after it enters the orbit. After the evaluation is completed, it will transfer to the long-tube autonomous flight; Carry out rendezvous and docking missions, astronaut on-orbit resident missions, and propulsion and supplementary missions. Since the execution time of these missions is longer than the time for orbital testing, special on-orbit testing of mission-related functions is r...
