This invention discloses a method for analyzing the configuration stability of a high-precision space measurement constellation based on decoupled state transition tensors, belonging to the field of space technology. The method involves: decoupling the influence of different perturbations on configuration stability; establishing a mapping relationship between the spacecraft's orbital state and configuration stability indices; substituting the obtained orbital state transition tensor expression for perturbation decoupling into the method to obtain the state transition tensor expression for the configuration stability indices; analyzing and obtaining the influence of different perturbations on configuration stability, thereby supporting the optimization of the high-precision space measurement constellation configuration, improving the performance of the high-precision space measurement constellation system, and increasing detection accuracy. This invention has the advantages of high accuracy and high efficiency in analyzing the configuration stability of high-precision space measurement constellations, which is beneficial for the rapid iterative optimization of high-precision space measurement constellation configurations and for improving the stability and detection performance of high-precision space measurement constellation configurations.

This invention relates to a method for verifying a structured startup module for spaceborne software, belonging to the field of space technology. The invention verifies the structured startup module of spaceborne software, checking whether the software's operating state is consistent with the design under conditions such as initial power-on, reset, system disconnection, and power-off, whether it can transition to the normal operating process, and whether it can guarantee the normal operation of the spacecraft. This invention verifies, on the one hand, the rationality of the software design and whether it can achieve the expected results; on the other hand, it verifies the correctness of the software logic, verifying the operating logic of the computer upon initial power-on, as well as the correctness of fault logic and process jumps, ensuring the stable operation of the spacecraft in orbit.

This invention relates to the field of space technology experiment evaluation, and more particularly to a method for analyzing the necessity of on-orbit verification of payloads based on the space environment. The method includes acquiring experimental requirement data for the space technology to be verified, including environmental parameter requirements, on-orbit operational requirements, manned spacecraft on-orbit platform resource requirements, and cost and risk data related to the experiment. Based on the acquired experimental requirement data, a comprehensive index of environmental irreplaceability is calculated. N E Human-loop dependency comprehensive index D H Platform compatibility comprehensive indicators A P and comprehensive benefit gain indicators G B Based on the four calculated indicators, and according to the preset three-level judgment rules, the necessity judgment conclusion for the on-orbit test of the manned spacecraft is output. This invention quantifies the unsimulability of the multi-factor coupled environment, the irreplaceability of human-machine collaboration, and the platform matching degree, providing objective decision support for test planning and optimizing the on-orbit resource allocation of manned spacecraft.
