CubeSat Prototype Test Flight 1 – Debrief & Next Steps

Join the Discord: https://discord.gg/yeusgM75ys My #cubesat #prototype SN1 soared to the stratosphere and was recovered! But progress isn’t always smooth, and this flight had its fair share of challenges. In this video I share what went wrong, what worked, and how we’ll move forward from here. ## Update - Found the latitude offset bug (15:55): Latitude uses 2 digits for degrees, but longitude uses 3 – and I was parsing 2 digits as degrees for both 🤦🏻‍♂️ *Dev kit shop will be up in late 2025 / early 26* – get pinged: https://forms.gle/5a2UZdfcyUmFjTZd8 ## 🛰️ Support This Project If you are looking for a way to support this channel, leave a tip or become a member :) - Channel Memberships: https://www.youtube.com/channel/UCLf9aKlW-TbC8zbrl0OvKLQ/join - Patreon: https://patreon.com/buildacubesat - Ko-fi: https://ko-fi.com/buildacubesat - PayPal: https://tinyurl.com/bac-donate ## ⏱️ Timestamps 00:00 Intro 01:02 Test Flight 1 Recap 01:55 MCUs No LoRa / LTE Telemetry 02:17 CM5 Video Stream Problems 03:45 CM5 journalctl Log 06:38 CM5 Interconnect Failure 07:55 MCU1 Log 08:54 Future Vibration Testing 09:29 MCU2 Log 10:29 LightAPRS 11:56 Launch and Recovery 15:08 Test Flight 1 Data 22:09 Operational Learnings 24:20 Some stuff worked 25:30 Test Flight 2 Goals 27:32 Outro ## 📺 Relevant Episodes - CubeSat Prototype SN1 Integration – Part 1 of 2: https://youtu.be/rJpBSVUeIH4 - CubeSat Prototype SN1 Integration – Part 2 of 2: https://youtu.be/O2iDsUYIIP4 ## 🌐 External Links - Marimo: https://www.youtube.com/@marimo-team - APRS.fi: https://aprs.fi/ - QRP Labs LightAPRS W 2.0: https://qrp-labs.com/lightaprsw2.html - RaspberryPi APRS iGate Setup: https://www.regnatarajan.com/radio/create-aprs-receive-only-igate-raspberry-pi ## 🏔️ Repo Links - Test Flight Data: https://codeberg.org/buildacubesat-project/bac-software/src/branch/main/habSat-25.1/flight-data ## 🎥 Video Credits - @robinsonspace CubeSat Space Qualification Testing: https://www.youtube.com/watch?v=Uj0ofGOwHLw --- Need a friendly, non-corporate GitHub/GitLab alternative?
