What Does PFU Stand For?
PFU stands for Proto Flight Unit
The Proto Flight Unit (PFU) is a preliminary version of a spacecraft or satellite designed for testing and validation before the final production model is developed. The PFU undergoes rigorous evaluation to ensure that all systems function correctly and meet operational requirements, serving as a critical step in the aerospace development process. It allows engineers to identify and address potential issues early, thereby reducing risks and enhancing the reliability of the final design.
