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.
