Partitioning Spacecraft into Subsystems

How To Partition Spacecraft Into Subsystems

Purpose of the guide

  • This guide is for a space engineer who is designing and building a spacecraft and needs guidance on partitioning the spacecraft into subsystems.

Step 1: Identify the main functions of the spacecraft

  • Define the primary mission objectives.

  • Evaluate any additional mission functions which may be required.

  • Identify any safety requirements.

  • Analyze the environment in which the spacecraft will be operating.

  • Determine the resources needed to achieve the mission objectives.

Step 2: Divide the spacecraft into structural and functional subsystems

  • Identify all of the major components of the spacecraft.

  • Divide the components into structural and functional subsystems.

  • Consider any existing subsystems which may need to be modified or replaced.

  • Develop a system architecture to ensure that all components are correctly connected and interact with each other correctly.

Step 3: Assign components to subsystems

  • Assign components to subsystems based on their function and purpose.

  • Ensure that all components are assigned to a suitable subsystem.

  • Consider the size, weight, power, and other requirements of each component when assigning it to a subsystem.

  • Ensure that redundant components are assigned to different subsystems to increase reliability.

Step 4: Assess the necessary components for each subsystem

  • Evaluate the performance requirements of each component.

  • Determine the number of components required for each subsystem.

  • Estimate the total cost of all required components for each subsystem.

  • Consider any potential risks associated with each component and its subsystem.

Step 5: Analyze the interaction between subsystems

  • Analyze how each subsystem interacts with other subsystems on the spacecraft.

  • Identify any potential conflicts between subsystems or between components within a subsystem.

  • Determine if any additional changes or modifications need to be made to ensure smooth operation of all subsystems.

  • Develop a detailed timeline which outlines the expected order of operations between subsystems.

Summary of main points

The main points of this guide are: 1. Identify the main functions of the spacecraft. 2. Divide the spacecraft into structural and functional subsystems. 3. Assign components to subsystems. 4. Assess the necessary components for each subsystem. 5. Analyze the interaction between subsystems.
