[0002] Satellite development is divided into three major stages: final assembly, integration, and testing and experimentation. The most critical of these is the testing and experimentation stage, which accounts for the largest proportion of the satellite development process. After the satellite is developed at the manufacturing plant, it enters the factory state and will be transported from the manufacturing plant to the launch site.
