  8. Activity Report Milestones, Tasks, and Health Report

  9. MILESTONES - STRUCTURES • Finalize 3-D model and run analysis • To complete this Milestone: • 3-D model including every parts of the structure must be completely assembled. • Finalize the design with respect to the requirements from NanoRacks and ISS. • Run the structural analysis. • Fabricate parts and assemble structure • To complete this Milestone: • Finalized drawings must be sent to Howe Welding & Metal fabrication • All parts must be fabricated within NanoRacks tolerances • Hard anodize (Liberty anodizing)  and assemble the structure.

  10. Task Breakdown - structures

  11. Milestones - Communications • Assemble, test, and Provide Data for a Ground Station and radio To Complete this milestone: • Provide data from orbital simulations • Work with ground station staff and HABET to assemble ground station • Perform tests with both radio and Ground station • Complete all regulation work To complete this milestone: • Finish all regulation work on time • Stay in touch with all regulatory bodies • Be prepared for any new forms

  12. Task Breakdown - Communications

  13. Milestones - electronics • Have Circuit Boards fully fabricated and flight ready. • Use KiCad to complete the design. • Have the boards populated once the components have been manufactured and delivered. • Have the Solar Arrays fully fabricated and flight ready. • Use KiCad to complete the design • Have the solar panels manufactured by a third party • Have the Payload completed and integrated into CySat-I  • Work with a team of CompE students to complete the development of the Payload • Have the Electronics Team integrate the Payload into CySat-I

  14. Task Breakdown - Electronics

  15. Project Health Report • Green, Yellow, Red. This is an honest assessment on how the project is doing currently

  16. Design Review - Structures Led by Mohammad Reza

  17. Design Overview - structures • Finalized design is within tolerances • Rail edges, standoffs, etc. • Finalized Solar panel layout • Materials for fabrication in stock (Al 6061-T6) Stowed view

  18. Design Overview - structures • EnduroSat antenna and Radio added • No need for Burn Wire (old) • Simplify Antenna Deployment • Antenna Added to Top Plate • Placement due to EnduroSat images • Ease of integration to current design Deployed View

  19. Design Overview - structures Exploded View

  20. Design Review - structures Constraints

  21. Design Constraints - structures RBF

  22. Design Review - structures Current Design

  23. Current Design - structures • Meets requirements • Confirmed from CAD fit with Nanoracks Deployer • All parts are designed • Currently running analysis • Supports other subsystem • TrisolX solar wings ​ • Spectrolab UTJs • ISS cells​

  24. Current Design - structures Z X Y

  25. Current Design - structures                                                                Dimensions (mm)

  26. Design Review - structures Proposed Changes

  27. Proposed Changes - structures • Threaded Rods are reduced in length. • To avoid major change on bottom plate • Payload antenna braces added • Newly added as not previously created • It consists of back plate and four front braces with bolts securing them • SDR Braces consist of four brackets • Four braces holding the SDR board in place • This will be fastened with M2 bolts

  28. Design Review - structures Design Risks

  29. Design Risks - structures

  30. Design overview - communications Led by Sam Ruhlin

  31. Radio • Commercial Off the Shelf (COTS) • Endurosat UHF Transceiver II • Data transferred at 9600 baud • GMSK modulation

  32. Ground Station • Responsible for all communication between CySat-1 and CySat team • Working with ISU staff for specific design • Rotor-antenna design maximizes communication time • STK scenario that models the orbit of CySat-1 • This scenario plots when we can talk to Cysat-1

  33. Design Constraints- communications

  34. Design Constraints - communications • Data cannot be encrypted/altered in any way • No images can be sent • Radio is limited to a frequency of 436.375 MHz • Data can only be sent in limited range • Directionally dependent antenna must be used

  35. Design Review - communications Current Design

  36. Current Design - communications • Commercial off the shelf radio produced by Endurosat • Currently going through ISU purchasing • Data will be transferred at 9600 baud • GMSK modulation • Ground station will use a pointer and a radio

  37. Design Review - communications Proposed Changes

  38. Proposed Changes - communications • Moving all required STK files to flash drives  • No major changes can be made to design due to COTS radio

  39. Design Review - communications Design Risks

  40. Design Risks - communications • Radio does not connect with ground station (High) • Mitigation: Regular testing of radio and ground station • Radio is not delivered on time (Medium) • Mitigation: staying on top of ISU purchasing and communicating with EnduroSat • Regulation documents are not successfully completed (Low) • Mitigations: Staying on top of new documents sent to us • Writing Documents thoroughly and promptly • STK files do not load properly (Low) • Mitigation: Files saved to a flash drive

  41. Design Review - electronics Led by Josh Gilmore

  42. Design overview - electronics • ADCS • Altitude Determination and Control System • Purchased from CubeSpace • Control's the stability of the satillite • Place below slide 44 electronics design overview

  43. ADCS Higher Level task list

  44. Design overview - electronics • Solar Panels • 3 types of solar cells • TrisolX solar wings  • Spectrolab UTJs • ISS Cells • Directly connected to the EPS • Covers outside side panels of CySat-I

  45. Design overview - electronics • Electrical Power System (EPS) from EnduroSat • Lithium Polymer Batteries recharged by solar arrays • Activated via RBF pin

  46. Design overview - electronics • Flight Computer / Motherboard • Duel STM32 system • FRAM provides radiation safe memory storage • Important GPIO can be switched between CPUs for redundancy • Made in M2I lab

  47. Design overview - electronics • Software Design Radio (SDR) • Picozed SDR 2X2 • Programmed to be used as a radiometer.

  48. Design overview - electronics • SDR Antenna • Scans the Earth's soil to detect moisture • Communicates to the SDR via a LNA board that will amplify the signal picked up by the antenna • Fabricated in M2I lab

  49. Design Review - electronics Constraints

  50. Design Constraints - electronics • Must fit within structure • Endure Low Earth Orbit environment • Must point towards Earth to broadcast information • Careful consideration of power budget and link budget to operate all components
