Study Notes

Space Mission Analysis and Design Process

  • The key to the space mission analysis and design process is to define broad mission objectives and constraints at the beginning.
  • The primary focus when designing a space system is to achieve overall objectives such as communication, navigation, or observation.

Procurement Plans for Space Systems

  • A common problem in procurement plans for space systems is that detailed technical specifications are often substituted for broad mission objectives.
  • This substitution can lead to inefficient use of resources and ineffective system design.

Achieving Overall Objectives

  • To achieve overall objectives, it is essential to focus on the key performance parameters and allocate resources accordingly.
  • The text emphasizes that overall objectives such as communication, navigation, or observation will remain generally the same.

Optimizing Performance and Cost

  • To get the most performance for the money spent on space systems, it is essential to optimize system design and resource allocation.
  • The text suggests that achieving the most performance for the money involves defining broad mission objectives and constraints at the beginning of the design process.

Initial Step in Space Mission Analysis

  • The initial step in the space mission analysis and design process is to define broad mission objectives and constraints.
  • This step is important because it sets the foundation for the entire design process and helps to ensure that the system meets its intended objectives.
