  3. User Notes • You may reformat this to fit your design, but be sure to cover at least the information requested on the following slides • This template contains all of the information you are required to convey at the CDR level. If you have questions, please don’t hesitate to contact me directly: rocksatx@gmail.com

  4. Purpose of CDR • Confirm that: • Design is mature enough to move into the fabrication phase • Final analysis on systems that weren’t prototyped or needed further analysis is complete and accurate • Results of prototyping suggest the system will meet project requirements • Manufacturing plan is in place • Testing plan is in place and sufficient to ensure system functionality and performance in-flight • Project meets requirements of RockSat-X user’s guide • The project is on track to be completed on time and within budget

  5. CDR Presentation Outline • Section 1: Mission Overview • Section 2: Design Description • Section 3: Subsystem Design • Section 4: Prototyping/Analysis • Section 5: Manufacturing Plan • Section 6: Testing Plan • Section 7: User Guide Compliance • Section 8: Project Management Plan

  6. 1.0 Mission Overview Name of Presenter

  7. Mission Overview • Mission statement • What do you expect to discover or prove? • Who will this benefit and/or what will your data be used for?

  8. Theory and Concepts • Give a brief overview of the underlying science concepts and theory • What other research has been performed in the past? • Results?

  9. Mission Requirements: • Project requirements  derived from mission statement • Break down into mission objectives, system level objectives • Please show traceability and linkages • See example on following slide crestock.com

  10. Mission Requirements: crestock.com

  11. Success Criteria: • Define Minimum Success: What is the least amount of data you can collect that will still constitute a success? • Comprehensive Success: Under ideal conditions, what would constitute comprehensive mission success?

  12. Expected Results • This is vital in showing you understand the science concepts • Go over what you expect to find • Ex. What wavelengths do you expect to see? How many particles do you expect to measure? How well do you expect the spin stabilizer to work (settling time?)? How many counts of radiation? etc

  13. Concept of Operations • Based on science objectives, describe what the payload will be doing during flight and highlights areas of interest • Include all significant events during your flight • RS-X 2012 Mission timeline included on following slide for guidance • You may used the example on following slide updated with your mission events • Complete your Timer Events Matrix in xls format and submit • Include screen shot of this matrix in your presentation

  14. Concept of Operations • Example of Timer Events Matrix for presentation

  15. Example ConOps Altitude t ≈ ??? Altitude: ?? km Event B Occurs t ≈ ??? Altitude: ?? km Event C Occurs t ≈ ??? Altitude: ?? km Event A Occurs Apogee t ≈ 199.7 sec Altitude: ≈153 km t ≈ ??? Altitude: ?? km Event D Occurs End of Malemute Burn t ≈ 28.7 sec Altitude: 17.2 km t ≈ 454.9 sec Chute Deploys -G switch triggered -All systems on -Begin data collection t = 0 min t ≈ 876 sec Splash Down

  17. 2.0 Design Description Name of Presenter

  18. Actions from PDR • Please update me on your actions assigned during PDR

  19. Changes Since PDR • What major changes have you made since PDR? • Why were these changes made? • Do these change any of your mission objectives/requirements?

  20. Design Overview: Functional Block Diagrams • Functional block diagram • Show all major and minor subsystems and how they are interconnected • Show voltage levels and data lines • Show all power and data storage • Show mechanical and electrical inhibits • Show Wallops interface (power/telemetry) • Example on following slide • I will spend a lot of time on this diagram with each team and it will be referred to all the way up until launch so make it good

  21. Example Functional Block Diagram

  22. Mechanical Design Elements • Give me a brief overview of your final mechanical design • Mechanical drawings should be included • Solid models (labeled) with many views should be included • Any stress/strain analysis? • Material choices?

  23. 3D image of our payload

  24. Electrical Design Elements • Give me a brief overview of your final electrical design • Overall electrical schematicsshould be presented • Sensor specification and how they meet your requirements

  25. System Electrical Diagram

  26. Software Design Elements • Give me a brief overview of your final software design • Software flow diagram should be included • Could include State diagrams • Could include function overviews (input/output)

  27. De-Scopes and Off-Ramps • If there are portions of your project with lots of risk, do you have “off-ramps” in case you run into schedule/budget constraints? • Describe these “De-Scopes” and “off-ramps” that may be used in the future

  28. 3.0 Subsystem Design Name of Presenter

  29. Subsystem Design • Start with your organization chart with each of your subsystems labeled • Detail each subsystem’s final design • Each subsystem should be separated on to its own slide • Each subsystem should cover: • Drawing • Power and data • Mechanical and Electrical Interfaces • Weight • Critical technology used and current issues grandpmr.com

  30. Organizational Chart • What subsystems do you have? • Who works on each subsystem? • Leads? • Don’t forget faculty advisor/sponsor(s) Project Manager Shawn Carroll System Engineer Riley Pack Faculty Advisor Chris Koehler CFO Shawn Carroll Safety Engineer Chris Koehler Faculty Advisory Emily Logan Sponsor LASP Testing Lead Jessica Brown EPS David Ferguson Riley Pack STR Tyler Murphy Aaron Russert DEP Aaron Russert Shawn Carroll PM Kirstyn Johnson Elliott Richerson
