Members:

• Anthony Vareberg (Team Lead)
• Elizabeth Janson
• Sarah DeMatteis
• Vanessa Whitehead
• Zachary Anderson

Goals:

• Redesign the CAD model to accommodate new solar panels
  • Redesign structure rails
  • Redesign support brackets
  • Redesign payload brackets
  • Redesign spacers
• Fabricate new structure components
  • Rails
  • Support brackets
  • Payload brackets
  • Spacers
• Test EPS battery cells
• Assembly of the satellite with new hardware
  • Hardware refers to tested EPS, new solar panels, and fabricated structure components
• Assist with programming tasks for integration and testing purposes

Deliverables:

• Completed CAD model of the satellite
• Fully assembled satellite
• EPS and solar panel test data

Milestones and Tasks:

• Completed CAD model of the satellite
  • This semester, the team has been able to nearly complete the CAD Model, including:
    • Designing new sun sensor boards
    • Importing the new solar panel CAD models
    • Resizing the rails and bracket mounting locations to accommodate the new solar panels

• Fabrication of new rails, support brackets, and payload brackets for the structure
  • Spacers have been designed, printed, and installed throughout the stack for structural stability
  • The team is currently working with a metal fabrication shop to create new pieces that are made of aluminum

• Procurement of new EPS battery cells and solar panels
  • New solar panels have been chosen
    • The team is currently awaiting funding for these components
  • New EPS battery cells have arrived and are awaiting certification testing
    • A new EPS structure was designed, printed, and implemented to accommodate the new cells
• Assembly of the satellite
  • The stack has been assembled without exterior structural components
    • The team is awaiting correspondence from the metal fabrication shop about creating the necessary parts before beginning the full assembly

Mid April Progress Summary:

Thus far, the SolidWorks model was completed with new rails, brackets, spacers, sun sensor PCBs, and a new EPS case model. The spacers and EPS case were 3D printed, and the rails and brackets are awaiting fabrication by our manufacturer. The sun sensor PCBs, solar panels, and radiometer components will be ordered shortly as funds come in. Further, the battery cells have arrived and will be tested per NanoRacks procedures. In terms of overall assembly, the satellite is currently constructed with all components minus the payload, support brackets, and solar panels with accompanying sun sensors. Full assembly will likely occur in the summer due to pushbacks with funding procurement. Ultimately, the team has made great progress with the structures and systems for the satellite, and it is expected to be ready for handover in August.
