Information : Preferred Design Processes & Practices for Flight Hardware
The Advanced Digital and Power Subsystems Department of Sandia National Laboratories (SNL) developed two documents to provide standardization of processes and practices in space-based electronic payload design. These critical documents were compiled to capture personnel knowledge and expertise acquired during 30 years of development of electronic packages and power supplies for various satellite payloads. Using these documents has allowed SNL to train new personnel and provided an easier communication path to potential customers.
The documents encompass flight hardware for satellite payloads with sections on general guidelines/philosophies, preferred process phases such as system design, preliminary design, detailed design, implementation and test, integration and test, launch, and post-launch. The section on preferred practices addresses electrical, mechanical, environmental, robustness, safety, trouble-shooting, and documentation.
Training new personnel in technical aspects has required almost 90% less time by applying the information contained in these documents by focusing on previous problems identified from past experience and suggesting proven solutions. In addition, there is enhanced communication outside the department and standardization within it. These documents also provide a standard for performing quality reviews and reduce project costs by ensuring the job is done right the first time, and finally, the process is dynamic as new lessons from continuing experience are incorporated into the guideline documents.
