Lessons Learned Implementing Multi-Mission Sequencing Software

This paper will describe the software and its uses to provide context for its criticality. The different approaches that have been taken to implement the software in a multi-mission format will be outlined. The advantages and disadvantages as well as the lessons learned during development and maintenance of these different architectures will be discussed, Finally. the use of multi-mission software in operations and the lessons learned from using it will be discussed.This paper will provide valuable information to organizations exploring the use of multi-mission software. regardless of whether the change is to minimize spacecraft ground software development time or cost reduction. Similarly. the paper will provide insight into some of the steps that can be taken during software development and operational use that will minimize difficulty later.
