Autonomously managed spacecraft information system and method of operation thereof

Abstract

The invention proposes an autonomous-management spacecraft information system and an operation method thereof. The system employs a ground and spacecraft combined working mode to execute the autonomous task management. The system comprises five hardware subsystems: a task subsystem, a propulsion control management subsystem, a looped heating management subsystem, an energy source management subsystem, and a load management subsystem. The task subsystem is used for carrying out the task analysis, task planning and task evaluation for a spacecraft, and carrying out the real-time monitoring of each subsystem. The propulsion control management subsystem, the looped heating management subsystem, the energy source management subsystem and the load management subsystem are used for task execution and the feedback of a task execution result. Therefore, the invention provides a solution for the design of a spacecraft information system which is used for the long-time and superlong-distance spacecrafts and meets the requirements of hiding performances and high real-time performances. Meanwhile, the system reduces the manual control of an astronaut, effectively reduces the task cost, and provides a technological base for the subsequent autonomous or semi-autonomous formation cooperative work among the spacecraft.

Description

technical field [0001] The invention belongs to the field of aerospace telemetry and remote control and space data, relates to spacecraft information system design engineering, in particular to a self-managed spacecraft information system and its operation method, which uses the joint work mode of ground and spacecraft to perform autonomous task management, and spaceflight After receiving the mission information injected once or in batches, the sensor autonomously executes the mission and sends the telemetry information and mission execution results back to the ground periodically or after the mission is completed. Background technique [0002] The spacecraft information system realizes the acquisition, transmission, processing and utilization of spacecraft data. As one of the five pillars of the spacecraft (structural mechanism, heat and environment, control, energy, and data), it is the brain and nervous system of the spacecraft. [0003] The traditional spacecraft informa...

Problems solved by technology

If human participation is to be considered, a lot of development costs need to be increased to address many risk factors such as radiation

In addition, due to the long distance of the spacecraft performing deep space exploration missions, the traditional telemetry and remote control mode cannot meet the real-time requirements of the mission, which puts forward the demand for the autonomy of the mission management of the spacecraft.
