Assumptions:

• Assume payloads are selfie-sat and qeynet

Goal:

• Space-ready firmware by S25

High-level overview

• Admin

  • FMEA - F24
  • Requirements - W25 - Depending on when payload gets figured out

• Ground Station

  • Architecture design - F23
  • Communication stack (functional wireless comms) - F24
  • v1 Backend - S24 June Terminal MVP F24
  • v1 Frontend - S24 W25

• Firmware

  • EPS
    • MPPT - W25 - Mainly blocked by BMS
    • Load switch - F23 April F24
    • BMS - F23 W24 March W25
  • Comms
    • CC1120 TX/RX testing - F24
  • GNC
    • VN100 - W24
    • Motor feedback control (speed/position) - W24 - Not a requirement since rxn wheels will have that built-in
    • Control algo integration - depends on GNC
      • Earliest probably F24 S24 S25 for all algos integrated
    • Control algo testing - depends on GNC
      • Earliest probably F24 - Leave for GNC? Earliest S25 after control algos integrated
    • Other drivers (none have been sourced):
      • GPS - W24 S24 - talk to GNC not sourced W25/S25
      • Sun Sensors - S24 - Sourced W25 validated but F24 have smth written
      • Rxn Wheel - S24 S25 - 2 months once sourced
        • https://satsearch.co/products/cubespace-gen2-cube-wheel-cw0017
      • Magnetorquer - S24 S25 - Can be done as soon as sourced
  • CDH
    • Thermal - W24 - March - F24
    • State management - S24 W24 - March - F24/W25
    • UART Bootloader - F23
    • OTAP - F24 - August - S25
    • Telemetry management revamp - S24 - July W25
  • Payload
    • Qeynet (beacon and pointing) - unknown
    • Camera driver - W24 - April F24

• Infra

  • SIL - S24 S25 side quest- Scope out by March and determine feasibility
  • HITL - Scope out by March and determine feasibility - W25
    • Remote flashing - F23 - February
    • General infrastructure - W24
      • Depends on ground station comms progress
    • Test for each requirement - ongoing, but starts after infrastructure put in place

• Post space-ready side quests:

  • FPGA for EPS/GNC
  • More MCUs to split the workload and add redundancy
    • Inter-MCU protocol
  • New payload
  • Explore microSD alternatives
  • Publish a paper
    • Ideas:
      • Design of a HITL system for CubeSats
