  • Align on Big Quad 2025

  • Create a new arch doc for this, cloned from 2023 arch document (90% is unchanged)

  • Objectives & Timelines

    • Plans for peggy 2

      • Are we moving the electronics over or using all different ones?

        • If moving everything takes a long time we will have no working pegasus-sized drone

        • Buy parts to fill in the gaps on peggy 2, creating a second drone

        • Can compare pegasus 1 and 2 in real world performance

        • Could use peggy 1 as pilot training drone

        • Would need two more motors and a pixhawk 6X as major components

        • Mech make a new pixhawk mount for peggy 2

      • EE has to do wiring

        • Message on discord and coordiante time to complete this

      • Timeline for this, discuss in discord

      • Avionics cover still in R&D phase

        • Research by end of month, start construction end of July

    • Any other major planned changes to the pegasus platform?

      • Angled landing gear? - gonna test out the new landing gear on Peggy 2 and then decide most likely

        • Not much of a benefit

      • Proper waterproofing - thermoforming might be possible

        • Built into avionics cover

        • No carbon fibre to avoid radio blockage

  • Discussion of airside vs groundside compute

    • Compute

      • Raspi 5 8GB on airside

      • Powered via USB, EE needs to make harness/set up power source for 5V@5A

      • All airside compute

    • Sensors

    • Telemetry and control links

      • Try to get LTE working reliably on raspberry pi

      • Get a hat with a quectel modem

      • Phone is 210g, LTE hat is 70g

      • Could use phone just as internet connection, turn on USB/ethernet tethering and stop using AndrUAV

      • Streaming logs is possible over ELRS too

      • Test one ELRS link with mavlink-rc (SuperG and Iflight), add another Airport link (ranger and EP1) for logs and autonomy

    • Autonomy goals and timelines, what support is required

      • Aiming for two weeks after midterms
