autonomous flight from 100,000ft

Hello all,I'm working on a 3 stage project that's focusing on getting a drone into LEO (lower Earth orbit). I'm basically going to use a helium weather balloon to elevate a hybrid rocket 70-100k ft in the air. I'm going to have the rocket equipped with GPS as well as gyroscope's and a Micro controller to guide the rockets flight path. Id have the rockets engines ignite Once the balloon pops at max alt. Assuming all that goes perfectly once the rocket reaches its max alt I'd have another automated system release the rockets payload which would be a solar powered micro drone equipped with camera and transmitter. My questions are would it even be able to transmit any signals from such a distance and would it be possible for me to preprogram an autonomous flight path for the drone instead of have it tumbling around out there?PS-I'm going to try it whether its possible or not soo I need optimistic rather than pessimistic advice.

  • Fun idea!

    My first recommendation is to research a bit on what others have done. David Windestal (formerly Flite Test) flew an FPV glider to 100,000 ft and there are some interesting insights you can gain from that. LINK, and DETAILED ARTICLE

    As you can see from his video, communication was a big big issue. I'm not a digital signal processing (DSP) engineer, but to accomplish your mission I recommend that either you become an expert on DSP, or find someone who is. That's going to be one of your biggest challenges.

    Side note: If I was going to pick an off-the-shelf transmitter/receiver for this project, I would pick an OpenLRS Tx/Rx, which are open source transmitters and receivers. Open source is awesome!

    Some things to note:

    - There is not a lot of air at 100,000 ft, so that micro drone will have a tough time maintaining altitude - and more likely will fall spectacularly back to earth, unless it has some gigantic propellers. Do these calculations or some ground experiments to determine whether it can maintain altitude.

    - To maintain attitude control (your second question, I think) you must have some kind of attitude control system. As is said above, propellers will most likely not work for this. Compressed air and a series of valves and nozzles is the cheapest bet. That's what the SpaceShipOne guys in Mojave did for their flight to... (see "Vehicle Description")

    Anyway, best of luck to you, and do keep us in the loop and updated - that's what the community is here for!

  • I'm curios about this if any one could answer it :)
